It took much time.

I found the answer from here.

1. Uninstall git client plugin
2. Restart, it would be automatically executed
3. Install git plugin, not git client. Git client is installed automatically too.
4. Confirm git is available and name it "default" on Manage Jenkins > Configure System

Enjoy!

[memo] this parser does not support specification null version null digester

Update your xercesImpl.jar!!! old xercesImpl.jar can not handle setXIncludeAware method.
2.9.1 helps you.

Thank you Coding in Color!!!
