I got the same error several times when mining different repos, is there any plan to release this bugfix in the near future? @tsantalis

@mo7aammd We will make a new release soon, but you don't have to wait.

You can make your own release from the latest commit.

If you use the tool as a maven dependency, the just change the version in build.gradle from 3.0.7 to 3.0.8 and run in command line gradle publishToMavenLocal This will make a new release in your local maven repository, which you can use it in your dependencies.

If you use the tool as command line, just run in command line ./gradlew distZip This will make a new version of the command line tool with all dependencies bundled.
