break (so you don't end up with the same file included twice)

nice

Yeah, isn't it...

or java_files.sort()

Add comment about deleting .class files (similar to chromium-jars.xml)

Shouldn't this indet match the ' above?

[cjhopman, 2013/03/15 22:44:39]

Actually, I think it should match the 'j' or the 'v'... but that looks funny.

How about this?

[Yaron, 2013/03/15 23:13:46]

My vi says it should match the quote, but this is fine.

+      '-Xlint:unchecked',
+      '-source', '1.5',

[newt (away), 2013/03/15 03:25:04]

I thought we used 1.6, but I trust you here

[cjhopman, 2013/03/15 22:44:39]

So, currrently, we use 1.6 for libraries and 1.5 for apks... :/

I think this should be changed to match apks (1.5 is the default from Android's
build scripts and the Android java libraries are based on 1.5).

+      '-target', '1.5',
+      '-classpath', ':'.join(classpath),

[Yaron, 2013/03/14 23:03:51]

Can you add the description fields to each of these

[cjhopman, 2013/03/15 22:44:39]

Done.

+  parser.add_option('--input-jars-paths')

[Yaron, 2013/03/14 23:03:51]

Any reason not to rename this classpath?

[cjhopman, 2013/03/15 22:44:39]

Done.
