Issue Summary

When a tag is deleted in Bitbucket and the repository and branch is checked out in Bamboo using source code checkout task. packed-ref folder under .git directory in the buildworkingdirectory still contains the reference to the deleted tag.

Steps to Reproduce

1) Create a plan in Bamboo and link it to a Bitbucket server repository.

2) Create a commit in anyone of the files in Bitbucket server repository and create a tag from this commit.

3) Run the plan in Bamboo and the plan should run successfully.

4) Delete the tag in Bitbucket server, this can be done from GUI or from the command line using the below 2 commands

git tag -d TAG_NAME
git push --delete origin refs/tags/TAG_NAME

5) Run the plan in Bamboo again.

Expected Results

1) The deleted tag should not appear under packed-ref folder under .git directory of the branch which was checked out under buildworkingdirectory

Actual Results

1) The packed-ref folder contains the reference of the deleted tag.

Example

1) In Bitbucket server I've create a tag named BAM-25769 for one of the commits, see below

2) I run the plan in Bamboo and check the packed-ref folder and can see reference of this tag which is good

# pack-refs with: peeled fully-peeled sorted 
ddc592b3a5e75b8c168764dddcb5a595dcfbd6fe refs/remotes/origin/master
ddc592b3a5e75b8c168764dddcb5a595dcfbd6fe refs/tags/BAM-25769

3) In Bitbucket server I go ahead and delete the tag and I can see no reference of this tag there, see below

root@bitbucket715:/var/atlassian/application-data/bitbucket/repositories/testrepo6# git tag
error: cannot run less: No such file or directory
BAM-25769
root@bitbucket715:/var/atlassian/application-data/bitbucket/repositories/testrepo6# git tag -d BAM-25769
Deleted tag 'BAM-25769' (was ddc592b)

 - [deleted]         TAG_NAME
root@bitbucket715:/var/atlassian/application-data/bitbucket/repositories/testrepo6# git tag
error: cannot run less: No such file or directory

4) If I check the packed-ref file in Bitbucket server for this Branch I will not find reference for this tag

# pack-refs with: peeled fully-peeled sorted 
dd44258f33f8b51ffd2f8583ab6bae5133543caf refs/remotes/origin/master

5) Run the plan again in Bamboo with Force cleaned build and Build directory cleaned, but the packed-ref file will contain the reference of the deleted tag.

# pack-refs with: peeled fully-peeled sorted 
ddc592b3a5e75b8c168764dddcb5a595dcfbd6fe refs/remotes/origin/master
ddc592b3a5e75b8c168764dddcb5a595dcfbd6fe refs/tags/BAM-25769

6) If you do a manual git clone in Bamboo for that particular branch packed-ref folder will not contain the reference of the deleted tag.

Workaround

Delete the cache of the affected repository in Bamboo server and agents post deleting the git tag in Bitbucket server as per Git cache removal in Bamboo.
This might increase the timing of the first build as Bamboo will retry to create the cache.
