It seems like the newer 6 version series of jgit is published against newer versions of JDK 8. 5.13.0.202109080827-r is the latest version that still supports JDK 8. I verified that this solves the problem locally but if you want to confirm that this solves the JDK 8 issues then merge https://github.com/scoverage/sbt-coveralls/pull/252 and then rebase main ontop of this PR.
