Table Of ContentsA plugin is a (zipped) folder with the following structure:
- classes/
The classes of your plugin
- lib/
Third-party dependencies (JAR files) used by your plugin
- plugin.properties
File for plugin configuration and metadata
The plugin.properties file provides metadata of your plugin. Most importantly, the
properties give your plugin
an identifier and configure a Spring configuration class that will be registered with the
application context. These are the supported properties:
- plugin.id
The ID of the plugin, must be unique, for example,
MyPlugin(required)- plugin.version
The version of the plugin following the Semantic Versioning Specification, for example,
1.2.3or1.0.0-SNAPSHOT(required)- plugin.configuration-class
The Spring Configuration class, for example,
com.acme.myplugin.MyPluginConfiguration(optional; required for Java extensions but not needed for plugins that only provide resources)- plugin.provider
The provider/author of the plugin, for example,
ACME(optional)- plugin.dependencies
Comma-separated list of plugin IDs, for example,
some-plugin,some-other-plugin. See Section, “Plugin Dependencies” for details. (optional)- plugin.add-on-for
The plugin ID of the plugin that this plugin is an add-on for, for example,
some-plugin(optional)
Maven Plugin
To create a plugin with Maven, you can use the coremedia-plugin-maven-plugin.
To this end, the packaging type of the pom must be set to coremedia-plugin, and the
coremedia-plugin-maven-plugin has to be added with extensions set to true.
The plugin will then create a plugin-zip during the package phase.
It is possible to provide a custom plugin.properties file
or to generate one using the configuration from the pom.
Example
@Import("SomePluginBeansConfig.class") @Configuration(proxyBeanMethods = false) public class MyPluginConfiguration { @Bean public MyExtension myExtension(SomeBean someBean) { return new MyExtension(someBean); } }
Example 4.4. com.acme.myplugin.MyPluginConfiguration
public class MyExtension implements SomeCoremediaExtensionPoint {
public MyExtension(SomeBean someBean) {
...
}
...
}
Example 4.5. com.acme.myplugin.MyExtension
