Hi:

I'm facing the following exception when building a project:

* Exception is:

It only happens when there's still no build directories. Once I get the error next time I do the build it works perfectly fine.

The only workaround I found if I wanted to execute a clean build was to execute:

gradle generateDebugSources && gradle build

Any ideas ?

The only reference I found about this issue was this one:

https://code.google.com/p/android/issues/detail?id=78090

Plugin Version

com.android.tools.build:gradle:0.14.2
me.champeau.gradle:gradle-groovy-android-plugin:0.3.4

Thanks!!
Keep Grooving :)

@mariogarcia Are you still seeing this issue with the latest release?

[mariogarcia]

Sorry I forgot completely about it. I've just tried and I'm still getting the same problem. I'll try to speak to the rest of the guys from the project in case they had more info about it.

[jaredsburrows]

0.3.6?

[mariogarcia]

I've narrowed the problem. The thing is that it only fails using Gradle 2.3. If you're using Gradle 2.2 to 2.2.1 everything works perfect. It seems that maybe is just a Gradle regression problem.

@mariogarcia I'm closing this issue since it appears to be a gradle problem. Please feel free to re-open if you are seeing it with the latest versions of gradle, android plugin, and the latest version of this plugin.
