How can I override a service implementation in an IntelliJ plugin?

How can I override the default service implementation of, say, FrameTitleBuilder in my intellij plugin?

I am using IntelliJ 12.1.4, I have correctly configured the environment for creating plugins.

Now I tried to add this to my plugin.xml in a new plugin project:

 <extensions defaultExtensionNs="com.intellij"> <applicationService serviceInterface="com.intellij.openapi.wm.impl.FrameTitleBuilder" serviceImplementation="com.my.package.MyFrameTitleBuilder" overrides="com.intellij.openapi.wm.impl.FrameTitleBuilder" /> </extensions>

However, it is not:

 org.picocontainer.defaults.DuplicateComponentKeyRegistrationException: Key com.intellij.openapi.wm.impl.FrameTitleBuilder duplicated

Can anyone suggest some tips?

Thank you in advance!

The "overrides" attribute is logical (in IntelliJ 13 anyway), set it to true and the old implementation will be deleted first.

 <extensions defaultExtensionNs="com.intellij"> <applicationService serviceInterface="com.intellij.openapi.wm.impl.FrameTitleBuilder" serviceImplementation="com.my.package.MyFrameTitleBuilder" overrides="true" /> </extensions>

Since I could not find a way in plugin.xml so that my plugin redefined the service implementation, I had to "replace" it manually through PicoContainer.

Take ApplicationManager.getApplication().getPicoContainer() and MutablePicoContainer it to MutablePicoContainer , and then you can unregister / reregister the component.

I would still like to know the correct format for this with plugin.xml , if possible.
