      Description

      Use of maven-release-plugin with the android-emulator-plugin fails because the logcat temporary log file is captured as a modified file in the maven workspace.

      I cannot easily work around this by adding a checkModificationExcludes entry into the release:prepare parameters because it does not take a wildcard filename (needed to match the logcat_*.log temporary filename).

      I have managed to workaround this by building a local copy of the plugin that uses a file suffix of .log~ (maven ignores that because it treats is as a backup file). Example patch snippet to do this below.

      -        final FilePath logcatFile = build.getWorkspace().createTempFile("logcat_", ".log");
      +        final FilePath logcatFile = build.getWorkspace().createTempFile("logcat_", ".log~");
      

      That is not a proper solution but it does work.

      I guess that the proper solution will involve generating a temporary file outside of the workspace somewhere on the build slave.
