This will be fixed in 1.130.

In the meantime, you can work around the issue by adding this to the body of the GvrBuildProcessor class:

#if UNITY_2018_1_OR_NEWER
  public void OnPreprocessBuild(BuildReport report) {
    OnPreprocessBuild(report.summary.platform, report.summary.outputPath);
  }
#endif

Fixed in v1.130.
