Ant: Adding custom entries to project.javac.classpath

[Pierre-Yves Ricau]

Hi,

When using an annotation processor with Ant + Android, we need to configure the "compile" task so that the processor jar is part of "classpathref". We can't just simply put this processor within the lib folder, because the processor is a compile time lib and not a runtime lib, so we don't want the processor to be part of the APK.

We currently have two ways to do this :

* either copy the "compile" task and add a new path to the project.javac.classpath definition (see here)

* or backup "project.all.jars.path" value before compile, add a new path to it, and restore its previous value after "compile" (see here).

Things would be a lot simpler for us if we could extend "project.javac.classpath", either directly, or by having it use a custom empty entry that we can override.

What do you think about this?

I know the future build system will be Gradle, and I can't wait for that to happen. But we will still have to support Ant users...

Cheers,

Py

yes we should do something like this. If you were willing to contribute this, it should be easy to accept.
