CircleCI Java 11 build fail - maven

Question

I have a small spring boot rest api. It was built in java 8, recently I switched to java 11 and have the following problem. It builds localy and works fine, but it can not build on circleci.com. It can not find tools.jar, because it isn't part of jdk since version 9. How can I find the dependency that triggers this?
I'm using intellij 2018.3. I tried looking at maven dependency tree, but there is no search option.
Once again, it works localy.
CircleCI error:
#!/bin/bash -eo pipefail

Answer 1

The problem was with cobertura plug in. It does not support java 11.
