Checkout Jenkins Pipeline Git SCM with credentials?

You can use the following in a pipeline:

git branch: 'master',    credentialsId: '12345-1234-4696-af25-123455',    url: 'ssh://git@bitbucket.org:company/repo.git'

If you're using the ssh url then your credentials must be username + private key. If you're using the https clone url instead of the ssh one, then your credentials should be username + password.

To explicitly checkout using a specific credentials

    stage('Checkout external proj') {        steps {            git branch: 'my_specific_branch',                credentialsId: 'my_cred_id',                url: 'ssh://git@test.com/proj/test_proj.git'            sh "ls -lat"        }    }

To checkout based on the configured credentials in the current Jenkins Job

    stage('Checkout code') {        steps {            checkout scm        }    }

You can use both of the stages within a single Jenkins file.

If you want to use ssh credentials,

  git(       url: 'git@github.com<repo_name>.git',       credentialsId: 'xpc',       branch: "${branch}"    )

if you want to use username and password credentials, you need to use http clone as @Serban mentioned.

    git(       url: 'https://github.com/<repo_name>.git',       credentialsId: 'xpc',       branch: "${branch}"    )
