在 Jenkins 管道中签出标签

Question

Tried using

checkout scm: [$class: 'GitSCM', 
  userRemoteConfigs: [[url: '${repoURL}']], 
  branches: [[name: 'refs/tags/${tag-version}']]],poll: false

This fails with an Authentication error. Is there any way other than using

withCredentials

to checkout tag in a Jenkinsfile

Answer 1

After spending, hours got here

Correct way to use GitSCM in declarative pipeline is

checkout scm: [$class: 'GitSCM', userRemoteConfigs: [[url: repoURL, credentialsId: credential]], branches: [[name: tag-version]]],poll: false

Not like I found in most places in web

checkout scm: [$class: 'GitSCM', userRemoteConfigs: [[url: repoURL], [credentialsId: credential]], branches: [[name: tag-version]]],poll: false

I also have to quote the credential id

stage('checkout') {
    steps {
        checkout([$class: 'GitSCM', branches: [[name: tagVersion]],
                  userRemoteConfigs: [[url: 'ssh://git@repo',
                                       credentialsId: 'my-user-id']]
                ])
        }
    }

Annoation

'my-user-id' is the id of the entry you will find on the credentials page.

But it's not the title you see in the dropdown select box in the gui.

Answer 4

我希望它像普通分支一样工作，您是否尝试过不使用“refs/tags/”前缀？

Answer 5

The authentication error has nothing to do with the tag - seems like 2 different issues.

You should add a credentialId to the userRemoteConfigs part, as such:

checkout scm: [$class: 'GitSCM', userRemoteConfigs: [[url: '${repoURL}'], [credentialsId: '${credential}']], branches: [[name: '${tag-version}']]],poll: false

Also, you can use the following format for variables:

checkout scm: [$class: 'GitSCM', userRemoteConfigs: [[url: repoURL], [credentialsId: credential]], branches: [[name: tag-version]]],poll: false

Answer 6

If one don't want to fiddle around with the cryptic syntax, I've been using this solution to switch to a dedicated tag or branch, especially if it's a job parameter and not clear if the given value is a branch or a tag:

git(
    credentialsId: '<your-cred-id>',
    url: "<your-repo-url>"
)
sh(script:"""
    git checkout \$(git rev-parse --verify ${GIVEN_BRANCH_OR_TAG})
""")

The result will be in detached head mode but for most cases that's not a problem anyway.
