Hi. Apologies for the super-late reply.
Is there a way to get the model that the android gradel plugin introduces?
In your project configurator, you can query any models you want (see the argument of the init() method) via the Tooling API. In your case, I can imagine that your plugin depends on the android plugin jar, queries the Android TAPI model defined in the jar and sets up the returned source folders on the target projects.
Also it does not look like the Gradle Container for Android projects ever resolves dependencies as none show up as they do for the Java projects I have.
I’m not sure about the correct behavior, but it might be that there are configuration scopes missed in the configuration. Buildship resolves the eclipse.classpath.(plus|minus)Configurations scopes and assigns them to the project. You could adjust the configuration with an init script that is injected via the invocationCustomizers extension point.
I took a look at the WTP Configurator but that just basically adds the missing deployment items. In the ecllipse Maven project you could configure based on the existance of a particular plugin (i.e. android-gradle-plugin)
You can do the same in ProjectConfigurator.init().
If the project configuator is not the appropriate extension point can you point me to a couple of other examples that might get me going?
It’s definitely the project configurator where you should contribute to Android support.
Again sorry for the late reply and let me know if I help with anything more.
