Workaround

Workaround #1

When pushing with jgit to Bitbucket use the --atomic flag with your command

And/or if you have not disabled Bitbucket Mesh and do not want to use the --atomic flag for every push you can add the following hosting.atomic-initial-push=false to the mesh.properties file located in BITBUCKET_HOME_DIR/mesh

Workaround #2

Use HTTPS when pushing to Bitbucket
