I think there's some problem with IntelliJ when it generates the R.java file, which leads to a problem in AndroidAnnotations because it can't resolve the resource id for my layout.
Here's my activity:
package com.airlocksoftware.canvastest;
import android.app.Activity;
import android.os.Bundle;
import com.googlecode.androidannotations.annotations.EActivity;
@EActivity(R.layout.main)
public class MyActivity extends Activity {
/**
* Called when the activity is first created.
*/
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
}
What's weird is that even if I comment out the annotation, and do setContentView(R.layout.main), it works fine even though R.java is never imported.
By the way, the layout is just a simple "Hello World". Nothing weird going on there.
No matter what I do, I can't get AndroidAnnotations to generate CanvasActivity_.java. My pom.xml looks like this:

The annotation processing set up like shown in this screenshot.
Basically I setup the processor path to point to the jar files in my local maven repo, as described here.
The projects sources are set up like shown in this screenshot.
No matter how I make / rebuild the project, nothing ever shows up in gen/aa (and thus I can't reference CanvasActivity_.java) I ran mvn clean install from the project root, which fails with this stacktrace.

Honestly I'm at a loss now. If anyone has an idea of what to do, that would be amazing. Thanks!
EDIT: here's the stub R.java generated by IntelliJ.
