Android Studio can't compile, but gradle cli CAN compile

Question

I have strange error with Android Studio 0.5.7 on Mac. I can't compile my project with gradle and ndk-build. It fails with this error:

FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':SKG:ndkBuild'.
A problem occurred starting process 'command 'ndk-build''

BUT, when I run ./gradlew compileArmDebugJava from CLI, project is sucessfully compiled.

error in android studio:

    Executing tasks: [:SKG:compileArmDebugJava]

Parallel execution with configuration on demand is an incubating feature.
Relying on packaging to define the extension of the main artifact has been deprecated and is scheduled to be removed in Gradle 2.0

Answer 1

Solved, removed last '/', changed line from this:

commandLine 'ndk-build', '-C', file('src/main/jni/').absolutePath

to this:

commandLine 'ndk-build', '-C', file('src/main/jni').absolutePath
