I'm trying to package a library (that depends on an AAR) as a jar.
I create a Jar task that has the javaCompile task's source, and I collect
all the dependencies. For any dependencies that are an AAR, I extract the
AAR, keeping only the sources and classes.jar. I then extract classes.jar
into it's parent folder (where the AAR source is), and this directory is
added as a source for the jar task. However, the packaged jar still doesn't
contain the sources from the AAR.
Does anyone have a better way to tackle this?
