Retrieving android.jar from a local repository

[Eric Hall]

Hey Guys,
I've put the android.jar in our local repository and I am trying to
retrieve it from there during the initial build instead of priming the
cache in the .m2/repository/... like what is done in your install
script. This is causing problems during the [aapt:compile] phase as for
some reason the android.jar doesn't get downloaded before this point.
If I do prime the cache with just the jar file and nothing else, during
the [compiler:compile] stage the android.pom that is in the local
repository does get downloaded correctly along with the other
dependencies for that project and everything succeeds.

Did you run into this problem as well and is that why you have that
helper script? If not can you think of any reason why the dependencies
don't seem to get resolved for this project until after the aapt compile?

I hope this question makes sense, I'm still pretty new to Maven and
haven't learned all the terminology yet.
Thanks for your help,
Eric

Here is the error :

Here is th snippet of my pom, with some of our project information taken
out.

Hey Guys,
Using the info I found here
http://docs.codehaus.org/display/MAVENUSER/Mojo+Developer+Cookbook
I was able to modify the aapt compiler to resolve the android.jar
dependency. Here's a patch let me know what you think.

I added  @requiresDependencyResolution compile to the aapt plugin. See if that solves your problem.

[Eric Hall]

That did it. Thanks! 

BTW as a newcomer to maven one of the things I have been struggling with is the documentation.    I've been wandering around on the  maven  homepage, and I've seen the "Better Builds with Maven" book.  But they don't usually seem to answer my questions. Do you have any good pointers?

Thanks again,
Eric

I think your best bet is: http://www.sonatype.com/book/ It's updated frequently.
