Expected Behavior

git-clone task succeeds

Actual Behavior

git-clone task fails

Steps to Reproduce the Problem

1. kubectl apply -f pipeline.yaml from the attached repro.zip
2. kubectl create -f pipelinerun.yaml from repro.zip
3. With git-clone version 0.7 it succeeds
4. With git-clone version 0.8 it fails

Additional Info

The failure occurs after this log line: [fetch-source : clone] + rm -rf /workspace/output//lost+found which I assume is because https://github.com/tektoncd/catalog/pull/1034 has git-clone executing as a non-root user.

Here is the code being executed at that time.

I tried working around this issue by tweaking the params in my pipeline.yaml:

    params:
    - name: deleteExisting
      value: "false"

But that just moves the error over to git-init:

[clone] + /ko-app/git-init '-url=https://github.com/bendory/mini-true.git' '-revision=' '-refspec=' '-path=/workspace/output/' '-sslVerify=true' '-submodules=true' '-depth=1' '-sparseCheckoutDirectories='
