Issues with maven-android-plugin with maven-proguard-plugin

[prenaud76 <pa...@ericsson.com>]

Hi all.


I am having all sorts of issues with maven-android-plugin together with
maven-proguard-plugin. I managed to sort out most of them, but I just can't
get rid of this final one. And I just don't understand what's happening
really.


It works well if I call android:dex separately from proguard:proguard. For
example, all is fine if I do:


% mvn proguard:proguard

% mvn android:dex android:apk


The end result is a nicely packaged .apk file including the obfuscated
classes. But if I do it this way, which is a simplification of the goals
invoked by the package phase:


% mvn proguard:proguard android:dex android:apk


Then I get the below error. I am under the impression that the proguard goal
might leave the environment in a not-so-good state, but I am not sure. And
even if it does, what can I do about it, other than report the problem and
hope for a fix.


Has anybody seen this issue before? And if so, have you been able to solve
it in one way or another? Any hint will be greatly appreciated.


Tx.
