plugin.xml file is an XML document in the
http://apache.org/cordova/ns/plugins/1.0. It contains a top-level
plugin element that defines the plugin, and children that define the
structure of the plugin.
A sample plugin element:
<?xml version="1.0" encoding="UTF-8"?> <plugin xmlns="http://apache.org/cordova/ns/plugins/1.0" xmlns:android="http://schemas.android.com/apk/res/android" id="com.alunny.foo" version="1.0.2">
plugin element is the plugin manifest's top-level element. It
features the following attributes:
xmlns(required): The plugin namespace,
http://apache.org/cordova/ns/plugins/1.0. If the document contains XML from other namespaces, such as tags to be added to the
AndroidManifest.xmlfile, those namespaces should also be included in the top-level element.
id(required): A reverse-domain style identifier for the plugin, such as
version(required): A version number for the plugin, that matches the following major-minor-patch style regular expression:
engines and engine Elements
The child elements of the
<engines> element specify versions of
Apache Cordova-based frameworks that this plugin supports. An example:
<engines> <engine name="cordova" version="1.7.0" /> <engine name="cordova" version="1.8.1" /> <engine name="worklight" version="1.0.0" platform="android" scriptSrc="worklight_version"/> </engines>
Similar to the
version attribute, the specified
version string should match a major-minor-patch string conforming to
the regular expression:
Engine elements may also specify fuzzy matches to avoid repetition,
and to reduce maintenance when the underlying platform is updated.
Tools should support a minimum of
<engines> <engine name="cordova" version=">=1.7.0" /> <engine name="cordova" version="<1.8.1" /> </engines>
<engine> tags also has default support for all of the main platforms Cordova exists on.
cordova engine tag means that all versions of Cordova on any platform must
satisfy the engine version attribute. You may also list specific platforms and their versions
in order to override the catch-all
<engines> <engine name="cordova" version=">=1.7.0" /> <engine name="cordova-android" version=">=1.8.0" /> <engine name="cordova-ios" version=">=1.7.1" /> </engines>
Here's a list of the default engines that the '
- 'android-sdk' // returns the highest Android api level installed
- 'apple-xcode' // returns the xcode version
- 'apple-ios' // returns the highest iOS version installed
- 'apple-osx' // returns the OSX version
- 'blackberry-ndk' // returns the native blackberry SDK version
Specifying custom Apache Cordova-based frameworks should be listed under the engine tag like so:
<engines> <engine name="my_custom_framework" version="1.0.0" platform="android" scriptSrc="path_to_my_custom_framework_version"/> <engine name="another_framework" version=">0.2.0" platform="ios|android" scriptSrc="path_to_another_framework_version"/> <engine name="even_more_framework" version=">=2.2.0" platform="*" scriptSrc="path_to_even_more_framework_version"/> </engines>
A custom Apache Cordova-based framework requires that an engine element includes the following attributes:
name(required): A human-readable name for your custom framework.
version(required): The version that your framework must have in order to install.
scriptSrc(required): The script file that tells plugman what version of the custom framework is. Ideally, this file should be within the top level directory of your plugin directory.
platform(required): Which platforms that your framework supports. You may use the wildcard
*to say supported for all platforms, specify multiple with a pipe character like
android|ios|blackberry10or just a single platform like
plugman aborts with a non-zero code for any plugin whose target project does not meet the engine's constraints.
<engine> tags are specified, plugman attempts to install into
the specified cordova project directory blindly.
A human-readable name for the plugin, whose text content contains the name of the plugin. For example:
This element does not (yet) handle localization.
A human-readable description for the plugin. The text content of the element contains the description of the plugin. An example:
<description>Foo plugin description</description>
This element does not (yet) handle localization.
Plugin author name. The text content of the element contains the name of the plugin author. An example:
<author>Foo plugin description</author>
Plugin keywords. The text content of the element contains comma separated keywords to describe the plugin. An example:
Plugin license. The text content of the element contains the plugin license. An example:
<license>Apache 2.0 License</license>
One or more elements listing the files or directories to be copied
into a Cordova app's
www directory. Examples:
<!-- a single file, to be copied in the root directory --> <asset src="www/foo.js" target="foo.js" /> <!-- a directory, also to be copied in the root directory --> <asset src="www/foo" target="foo" />
<asset> tags require both
Web-only plugins contains mostly
<asset> elements. Any
elements that are nested within
<platform> elements specify
platform-specific web assets, as described below. Attributes include:
src(required): Where the file or directory is located in the plugin package, relative to the
plugin.xmldocument. If a file does not exist at the specified
srclocation, plugman stops and reverses the installation process, issues a notification about the conflict, and exits with a non-zero code.
Where the file or directory should be located in the Cordova app, relative to the
wwwdirectory. Assets can be targeted to subdirectories, for example:
js/experimentaldirectory within the
wwwdirectory, unless already present, then copies the
new-foo.jsfile and renames it
foo.js. If a file already exists at the target location, plugman stops and reverses the installation process, issues a notification about the conflict, and exits with a non-zero code.
from having to add a
<script> tag for each file. While
tags simply copy a file from the plugin subdirectory into
<js-module> tags are much more sophisticated. They look like this:
<js-module src="socket.js" name="Socket"> <clobbers target="chrome.socket" /> </js-module>
When installing a plugin with the example above,
socket.js is copied
www/plugins/my.plugin.id/socket.js, and added as an entry to
www/cordova_plugins.js. At load time, code in
cordova.js uses XHR
to read each file and inject a
<script> tag into HTML. It adds a
mapping to clobber or merge as appropriate, as described below.
Do not wrap the file with
cordova.define, as it is added
automatically. The module is wrapped in a closure, with
require in scope, as is normal for AMD modules.

<dependency> tag allows you to specify other plugins on which the
current plugin depends. While future versions will access them from
plugin repositories, in the short term plugins are directly referenced
as URLs by
<dependency> tags. They are formatted as follows:
<dependency id="com.plugin.id" url="https://github.com/myuser/someplugin" commit="428931ada3891801" subdir="some/path/here" />
id: provides the ID of the plugin. It should be globally unique, and expressed in reverse-domain style. While neither of these restrictions is currently enforced, they may be in the future.
url: A URL for the plugin. This should reference a git repository, which plugman attempts to clone.
commit: This is any git reference understood by
git checkout: a branch or tag name (e.g.,
0.3.1), or a commit hash (e.g.,
subdir: Specifies that the targeted plugin dependency exists as a subdirectory of the git repository. This is helpful because it allows the repository to contain several related plugins, each specified individually.
In the future, version constraints will be introduced, and a plugin repository will exist to support fetching by name instead of explicit URLs.
Relative Dependency Paths
If you set the
url of a
<dependency> tag to
"." and provide a
subdir, the dependent plugin is installed from the same local or
remote git repository as the parent plugin that specifies the
Note that the
subdir always specifies a path relative to the root
of the git repository, not the parent plugin. This is true even if you
installed the plugin with a local path directly to it. Plugman finds
the root of the git repository and then finds the other plugin from
<platform> tag identifies platforms that have associated native
code or require modifications to their configuration files. Tools
using this specification can identify supported platforms and install
the code into Cordova projects.
and therefore installable on any and all platforms.
A sample platform tag:
<platform name="android"> <!-- android-specific elements --> </platform> <platform name="ios"> <!-- ios-specific elements --> </platform>
name attribute identifies a platform as supported,
associating the element's children with that platform.
Platform names should be lowercase. Platform names, as arbitrarily chosen, are listed:
<source-file> element identifies executable source code that
should be installed into a project. Examples:
<!-- android --> <source-file src="src/android/Foo.java" target-dir="src/com/alunny/foo" /> <!-- ios --> <source-file src="src/ios/CDVFoo.m" /> <source-file src="src/ios/someLib.a" framework="true" /> <source-file src="src/ios/someLib.a" compiler-flags="-fno-objc-arc" />
It supports the following attributes:
src(required): Location of the file relative to
plugin.xml. If the
srcfile can't be found, plugman stops and reverses the installation, issues a notification about the problem, and exits with a non-zero code.
target-dir: A directory into which the files should be copied, relative to the root of the Cordova project. In practice, this is most important for Java-based platforms, where a file in the
com.alunny.foopackage must be located within the
com/alunny/foodirectory. For platforms where the source directory is not important, this attribute should be omitted.
As with assets, if the
source-filewould overwrite an existing file, plugman stops and reverses the installation, issues a notification about the problem, and exits with a non-zero code.
framework(iOS only): If set to
true, also adds the specified file as a framework to the project.
compiler-flags(iOS only): If set, assigns the specified compiler flags for the particular source file.
Identifies an XML-based configuration file to be modified, where in that document the modification should take place, and what should be modified.
Two file types that have been tested for modification with this
config-file element only allows you to append new children to an
XML document tree. The children are XML literals to be inserted in the
Example for XML:
<config-file target="AndroidManifest.xml" parent="/manifest/application"> <activity android:name="com.foo.Foo" android:label="@string/app_name"> <intent-filter> </intent-filter> </activity> </config-file>
<config-file target="*-Info.plist" parent="CFBundleURLTypes"> <array> <dict> <key>PackageName</key> <string>$PACKAGE_NAME</string> </dict> </array> </config-file>
It supports the following attributes:
The file to be modified, and the path relative to the root of the Cordova project.
The target can include wildcard (
*) elements. In this case, plugman recursively searches through the project directory structure and uses the first match.
On iOS, the location of configuration files relative to the project directory root is not known, so specifying a target of
If the specified file does not exist, the tool ignores the configuration change and continues installation.
parent: An XPath selector referencing the parent of the elements to be added to the config file. If you use absolute selectors, you can use a wildcard (
*) to specify the root element, e.g.,
parentdetermines under what parent key the specified XML should be inserted.
If the selector does not resolve to a child of the specified document, the tool stops and reverses the installation process, issues a warning, and exits with a non-zero code.
This is outdated as it only applies to cordova-ios 2.2.0 and
below. Use the
<config-file> tag for newer versions of Cordova.
<config-file target="config.xml" parent="/widget/plugins"> <feature name="ChildBrowser"> <param name="ios-package" value="ChildBrowserCommand"/> </feature> </config-file>
Specifies a key and value to append to the correct
file in an iOS Cordova project. For example:
<plugins-plist key="Foo" string="CDVFoo" />
resource-file and header-file Elements
Like source files, but specifically for platforms such as iOS that distinguish between source files, headers, and resources. iOS Examples:
<resource-file src="CDVFoo.bundle" /> <resource-file src="CDVFooViewController.xib" /> <header-file src="CDVFoo.h" />
<resource-file src="FooPluginStrings.xml" target="res/values/FooPluginStrings.xml" />
Like source, resource, and header files, but specifically for platforms such as BlackBerry 10 that use user-generated libraries. Examples:
<lib-file src="src/BlackBerry10/native/device/libfoo.so" arch="device" /> <lib-file src="src/BlackBerry10/native/simulator/libfoo.so" arch="simulator" />
src(required): The location of the file relative to

Identifies a framework (usually part of the OS/platform) on which the plugin depends.
<framework src="libsqlite3.dylib" /> <framework src="social.framework" weak="true" /> <framework src="relative/path/to/my.framework" custom="true" />
src attribute identifies the framework, which plugman attempts
to add to the Cordova project, in the correct fashion for a given
weak attribute is a boolean indicating whether the
framework should be weakly linked. The default is
custom attribute is a boolean indicating whether the framework is one that is included as part of your plugin files (thus it is not a system framework). The default is
Additional information provided to users. This is useful when you require extra steps that can't be easily automated or are beyond plugman's scope. Examples:
<info> You need to install __Google Play Services__ from the `Android Extras` section using the Android SDK manager (run `android`). You need to add the following line to your `local.properties` android.library.reference.1=PATH_TO_ANDROID_SDK/sdk/extras/google/google_play_services/libproject/google-play-services_lib </info>
In certain cases, a plugin may need to make configuration changes
dependent on the target application. For example, to register for C2DM
on Android, an app whose package id is
require a permission such as:
In such cases where the content inserted from the
plugin.xml file is
not known ahead of time, variables can be indicated by a dollar-sign
followed by a series of capital letters, digits, or underscores. For
the above example, the
plugin.xml file would include this tag:
plugman replaces variable references with the specified value, or the
empty string if not found. The value of the variable reference may be
detected (in this case, from the
AndroidManifest.xml file) or
specified by the user of the tool; the exact process is dependent on
the particular tool.
plugman can request users to specify a plugin's required variables. For example, API keys for C2M and Google Maps can be specified as a command-line argument:
plugman --platform android --project /path/to/project --plugin name|git-url|path --variable API_KEY=!@CFATGWE%^WGSFDGSDFW$%^#$%YTHGsdfhsfhyer56734
To make the variable mandatory, the
<platform> tag needs to contain
<preference> tag. For example:
<preference name="API_KEY" />
plugman checks that these required preferences are passed in. If not, it should warn the user how to pass the variable in and exit with a non-zero code.
Certain variable names should be reserved, as listed below.
