Error accessing jar: java.util.zip.ZipException: zip END header not found

https://travis-ci.org/github/super-flat/lagom-pb/jobs/700952758

Hello geeks. There is something weird happening. I am able to locally test the application. Also when I checked the PR on travis it was good. However when I merge to the master branch the build keeps on failing.

Kindly assist

Thank you so much. I just set the jdk to 8 and everything seems working
