Eclipse is notorious for "the Eclipse way" to do things.

For example, when compiling Java classes, Eclipse insists on using its own compiler that is a lot less strict (in particular with generics) than javac. But Eclipse's compiler also violates the Java specifications: it does not run annotation processors as part of the compilation process as mandated, but simply ignores that requirement. It is possible -- on a project by project basis -- to configure the use of specific annotation processors. But that still fails most of the time because they are only run in case of full builds -- when Eclipse's default mode is to build the code incrementally.

This project demonstrates how to add a custom builder to your project that other developers will inherit when checking out your project. The relevant change is labeled "Add the extra builder required by Eclipse's violating the Java specs".
