Sometimes when I use instant-run I get this error (mainly after layout.xml changes):
FAILURE: Build failed with an exception.
What went wrong: Execution failed for task ':wear:transformClassesWithNewClassShrinkerForDevDebug'.
java.lang.IllegalArgumentException
Try: Run with --stacktrace option to get the stack trace. Run with --debug option to get more log output.
Now my project needs a rebuild otherwise wont run and continues on giving me the same error.
But if instead of rebuilding it again I use the cmd with ./gradlew :wear:assembleDevDebug the :wear:transformClassesWithNewClassShrinkerForDevDebug builds just fine and I'm able to run it again, though instant-run was lost.
So it fails when I try instant-run but it doesn't when cmd is used? Why is this happening?
Thanks.
EDIT: Opened an issue in google code here
EDIT 2:
To reproduce this error in the cmd I had to change my layout.xml, like commenting a view, and then run :wear:transformClassesWithNewClassShrinkerForDevDebug.
The output:
FAILURE: Build failed with an exception.
What went wrong: Execution failed for task ':wear:transformClassesWithNewClassShrinkerForDevDebug'.
java.lang.IllegalArgumentException
Try: Run with --info or --debug option to get more log output.
