Could you provide actual version details of the used appcompat-v7 version? You currently use compile 'com.android.support:appcompat-v7:+'
which should get the newest version available. This breaks reproducible builds (since building at different times will use different versions) as well as normal builds if you depend on a specific feature. E.g. if the build host does not server the latest appcompat version you require, it still builds without errors, but might fail on run. Also if Google yet again decides to push incompatible (beta) updates, which was done in the preface of android-L, this might be a problem as well.
