Great to see progress!  Which git repo do those files end up in after
you check out with repo?  There might need to be some kind of
'android-sdk-gradle-helper' package that just puts the build.gradle into
/usr/share/... for the other packages to find.

We've been using the full git repo names as the naming convention for
source packages, so this one should be:

  android-platform-tools-base

after the git repo:

  https://android.googlesource.com/platform/tools/base/

These probably should be built as part of another source package.  Do
you know which git repo those are built from?  Or maybe we need to
rethink the source package approach for the Java stuff if there is a
reliable place to get the sources.  With the C/C++ stuff, there is no
upstream source package besides the git.

Fully supporting maven would be good here, but it is optional for now.
It is something we can come back later to, like as part of the GSoC work
this summer.  Also, our goal is to fully replace the androidsdk-tools
source package with common approach across the whole Android SDK.

Great progress, thanks for the update!  Your lombok troubleshooting
sounds correct to me.  Also, upstream has been somewhat responsive to my
emails, so its worth trying.  I just emailed the addresses in the git
commits.
