not works with jenkinsFile

[fpitpit]

When i launch ./gradlew release in stage into jenkinsFile, I've got error message on pretagCommit task 👍

[Hillkorn]

Do you checkout via ssh and on the time gradle executes this it can pull/push? Does it run in a docker container and has no valid .ssh config there?

In general this error does not really seem to be jenkins pipeline related but rather an issue with the git command not working

[seenimurugans]

It does not work with Jenkins pipeline file. I tried running the ./gradlew release command enclosed within sshagent(credentials: ["xxx"]) but no luck.

Looks to me that it runs on a detached HEAD and therefore can't commit & push. Can you try to checkout a branch with your pipeline instead of a commit?

[seenimurugans]

I tried with explicit git checkout command(sh "_git checkout $GITBRANCH") and it works now.

I do not know how to configure Jenkins declarative pipeline to checkout to a specific branch rather than a detached HEAD(git checkout -f 12f3838aa6).

I added additional stage named checkout and switched to specific branch(git checkout $GIT_BRANCH).

So this plugin do not work with Jenkins pipeline without additional checkout step?

[Hillkorn]

It depends. How is your job triggered? Do you create releases manually or for every build?

I also have this problem right now. I want to use this plugin, but when Jenkins checks out the source code it uses a "detached HEAD" instead of the release branch as I expected. I'm at a loss of how to fix this. The work around that @seenimurugans mentioned could work, but why can't Jenkin's just use the release branch! I'll keep looking, but @seenimurugans let me know if you find a better way to make this work.

What I tried:

1. Created a Jenkins Multibranch Pipeline
2. Add git repository and credentials to scm section
3. Add Jenkinsfile to git repo in the release branch
4. Trigger build

I added additional stage named checkout and switched to specific branch(git checkout $GIT_BRANCH).

How were you able to pass the git credentials for checkout?

[Bragrel]

@craigtmoore You can try to add additional behavior to your Jenkins configuration. Your multibranch pipeline -> Configure -> Git -> Behaviours -> Add -> Check out to matching local branch. This worked for me.

[craigtmoore]

@Bragrel Hm.... that seems to have gotten past the 'HEAD detached at a11...', but now its asking for credentials again:

@craigtmoore I've added Jenkins' ssh-key to GitHub and using git@github.com:xxx/yyy.git format.

[craigtmoore]

Ah, I suppose I should use an ssh (rather than http) git url for it and use the keys so it doesn't prompt me for silly passwords. Thanks!

[craigtmoore]

Awsome, I got it to work. Thanks for your help Bragrel. For others, I followed this blog to generate the ssh keys, and add them to my gitrepo and to Jenkins: https://mohitgoyal.co/2017/02/27/configuring-ssh-authentication-between-github-and-jenkins/ After that, I selected them under the project's GIT settings.

I also forgot to include the '-Prelease.useAutomaticVersion=true' along with the gradle release so don't forget about that.

[abhishekhp]

Can this work with just https not having to switch to ssh as git token in used

[choweiyuan]

For those having trouble with Jenkins Pipeline.. I'm using Git Checkout via HTTPS, by adding the following additional Git Checkout property (Check out to matching local branch) would fix HEAD detached issue

The error that I initially have before setting the property: [2023-07-26T13:33:36.156Z] > Task :myProject-release:preTagCommit FAILED [2023-07-26T13:33:36.156Z] Running [git, push, --porcelain, origin, (HEAD detached from 1234e56dc4)] produced an error: [fatal: invalid refspec '(HEAD detached from 1234e56dc4)']
