get details of source repository from Jenkinsfile

问题

A Jenkinsfile uses a checkout scm command to retrieve the most recent commit from a linked Bitbucket respository.

What specific syntax needs to be added to the Jenkinsfile in order for the Jenkinsfile to be able to extract the repositorySlug, and projectKey from the source repository as variables, and then print out those variables as console output?**

Sample Jenkinsfile:

I tried to incorporate ideas from the Jenkins Pipeline SCM Step Documentation in the following example Jenkinsfile whose resulting logs will be shown further below:

node {
    // Clean workspace before doing anything
    deleteDir()

    try {
        stage ('Clone') {
            def commitHash = checkout(scm).GIT_COMMIT
            sh "echo 'Commit hash is: ${commitHash}'"
            println commitHash

            def repName = checkout(scm).repoName
            sh "echo 'Repository Name is: ${repName}'"
            println repName

            def rep = checkout(scm).repo
            sh "echo 'Repository is: ${rep}'"
            println rep

            def nm = checkout(scm).name
            sh "echo 'Name is: ${nm}'"
            println nm
        }
    } catch (err) {
        currentBuild.result = 'FAILED'
        throw err
    }
}

Current Output:

Here is the console output that Jenkins generates when running the preceding Jenkinsfile:

Note that the projectKey and the repositorySlug are available in the logs above in the form of:

http://<bitbucket-ip-on-lan>:7990/scm/JSP/jenkinsfile-simple-repo.git

Restated Question:

For the data above, what specific syntax would need to be added to the Jenkinsfile in order for the resulting Jenkins logs to print out the following:

The projectKey is: JSP
The repositorySlug is: jenkinsfile-simple-repo

回答1:

This should work, but there might be a simpler way I'm presently not aware of.

Basically, it retrieves the full URL returned by the SCM plugin, splits it by / and extracts the parts you need.

def repoUrl = checkout(scm).GIT_URL
def key = repoUrl.tokenize('/')[3]
def slug = repoUrl.tokenize('/')[4]
slug = slug.substring(0, slug.lastIndexOf('.')) //Remove .git
echo "The projectKey is: ${key}"
echo "The repositorySlug is: ${slug}"
