<resolved>Fail to build JVB

about one week ago, it was working well.

this morning when I compile it again, it report below error.

jdk version:
openjdk version “11.0.4” 2019-07-16

Use java 8, and if you retry do you see same error. If so try deleting your ~/.m2 folder and try again.

Do you still experience the issue? My best guess is that this was a
temporary github failure.

I have resolved it.

at first this is a git issue. then I downgrade the jdk from 11 to 8. everything good!

thanks!!
I have resolved
