@breskeby Can you take a look? Seems like an issue with the java home we pull for building bwc distros, specifically on windows CI hosts.

Task :distribution:bwc:maintenance:buildBwcOssZip is also failing with the same error.

should be fixed by moving back to gradle 6.6.1 on master and 7.x branches. I'll close this once all ci builds have passed

I think another failure just popped up on CI: https://gradle-enterprise.elastic.co/s/evort4spsvx6g

[breskeby]

@jtibshirani that is a different issue you see which should also be fixed by now. I'm closing this as windows CI jobs are passing again after the gradle downgrade
