Gradle build sometimes fails

We are using gitlab-ci to run android tests. Building and testing done with gradle (2.10).

First we were using latest docker image (1.0.3). Every build fails with this error:

ERROR: Build failed with: wait: no child processes

According to this thread #989 (closed) we downgrade runner to 1.0.0 c308176c and add --no-daemon option to gradle.

At the moment builds and test are successfull, but bulding APK fails with same error.

Interesting that sometimes in fails and sometimes not.
