Eclipse "Build Automatically" not cascading

java eclipse eclipse-indigo

I have a project in Eclipse (Indigo but similar in Helios) which has files in src/main/resources which get processed to generate *.java source files in target/generated-sources/xyz. The project settings have "Build Automatically" enabled so whenever these resource files are edited and saved the corresponding *.java files are generated. I've added target/generated-sources/xyz to the projects Build Paths. This all works perfectly.

The problem is that the changes to the generated *.java files are inconsistently rebuilt. If I have one of those files open in the editor, then it notices that it changed and asks if I want to reload it. Reloading the *.java files is enough for it to recognize that it has changed and trigger a rebuild. If I don't have it open then it doesn't automatically pick up the changes.

Any ideas on what I can do to let Eclipse (Indigo preferably) know that these generated files are being updated? Or better yet tell it to monitor those folders directly?

Thanks.

Try configuring Eclipse to automatically refresh. I'm not sure about Indigo, but in Helios, it's in Preferences → General → Workspace → Refresh Automatically.

Here it is in Indigo:
