cannot compile with the latest Indigo branch from rosjava

I actually get the following error in catkin after a catkin_make (and following properly the instructions of the tutorials):

-- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Now, I managed to track down the crash at this line in the Catkin plugin:

https://github.com/rosjava/rosjava_bootstrap/blob/indigo/gradle_plugins/src/main/groovy/org/ros/gradle_plugins/CatkinPlugin.groovy#L167

The error is Caused by: java.lang.NoClassDefFoundError: org/codehaus/groovy/runtime/typehandling/ShortTypeHandling. It does not make sense as the rest of rosjava works fine with that plugin.

I am actually opening a bug because I believe something simpler is happening. rosjava got updated to the latest gradle in https://github.com/rosjava/rosjava_bootstrap/commit/7d47ee42b4a00dd4bbceac80785b6e210fcab9ec but not the android_* packages, cf https://github.com/rosjava/android_core/blob/indigo/build.gradle#L18. BTW, a new gradle actually got released today, cf https://github.com/rosjava/rosjava_bootstrap/issues/42

Thx !

Getting there...caught in the middle of getting it all upgraded last week after android studio made a huge leap. I'll update here once I've got it working.

[vrabaud]

take your time, that works is awesome and very well documented. rosjava_* was a breeze to install. I just wanted to make sure you guys were aware of it :)

Confirmed I got the same error with the current code.

Just merged in alot of the code brought in by @talregev in #226. Also updated the gradle wrapper and this error's gone. Everything compiling nicely...and seems alot faster than I remember too. :neckbeard:

Haven't got to the other android stacks, nor uploaded these artifacts to the rosjava maven repo yet though.

[vrabaud]

and I can confirm all the android_* packages compile. Thx a bunch @talregev !

[talregev]

@vrabaud you're welcome

[vrabaud]

and https://github.com/rosjava/android_apps/pull/41 works for me too ! Thx !
