Hi Mark,

Thank you for looking into this.

I also run into the exact same error.

Currently, I just made a simple workaround with a few git command myself. 

I have tried: deleting the git folder, trying on a larget number of different slave nodes

 git version 2.18.0.windows.1

java version 

java -version
java version "1.8.0_171"
Java(TM) SE Runtime Environment (build 1.8.0_171-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.171-b11, mixed mode)

I also want to report that the error only happens for Bitbucket/multibranch pipeline.   single pipeline job with the exact same checkout(scm) command is completely fine.

This only started happening after we auto upgraded plugins last Friday 02/11/2018

The plugin version and their previous version is enclosed.

Thank you in advance!
