我有一个Jenkinsfile，它既可以用于带参数的触发作业，也可以用于通过Webhook启动的作业。通过Webhook启动的Jenkins工作非常完美。但是，触发的Jenkins作业会引发一个奇怪的错误：
hudson.remoting.ProxyException: groovy.lang.MissingMethodException: No signature of method: org.jenkinsci.plugins.workflow.job.WorkflowJob.getItem() is applicable for argument types: (java.lang.String) values: [<NAME OF THE TRIGGERED JENKINS JOB (I changed the name)>]
Possible solutions: getName(), getAt(java.lang.String), asItem(), delete(), getACL(), getApi()

Jenkinsfile的基本代码如下。
def isMasterBranch(gitBranch) {return gitBranch == 'master' }
def label = "slave-pod-${UUID.randomUUID().toString()}"
def podName = "jenkins-slave-build"
podTemplate(label: label, name:podName , yaml: """
k8 goodness
"""
) {
node(label) {
stage('Prepare') {
scmVars = checkout scm
commitHash = scmVars.GIT_COMMIT
commitBranch = scmVars.GIT_BRANCH
//FAILS ON THE NEXT LINE WITH THE MANUALLY TRIGGERED JOB
if (isMasterBranch(commitBranch)){
// WE GET TO THIS LINE WHEN WITH THE JOB KICKED OFF VIA WEBHOOK
}
}
}
"""
请注意，我关闭了已触发作业的轻量级scm签出，因为我正在让某人传递分支名称作为构建参数之一。
任何对此事的见识都将受到赞赏。
