Jenkins“java.lang.NoSuchMethodError：没有这样的 DSL 方法”对于 groovy lib 中定义的函数

Question

管道：

// ./vars/tools.groovy
@Library('my-lib') _

pipeline {
  ...
  post {
    failure {
      script {
        tools.findErrors(currentBuild.rawBuild)
      }
    }
  }
}

tools.groovy

：

def action1(rawBuild)
{
  println("-- action1 --")
  def res = []
  ...
  res.each{ println(it) }
  return res
}

def action2(List res, String line)
{
  println("-- action2 --")
  ...
}

def findErrors(rawBuild)
{
  def errors = action1(rawBuild)
  def res = []
  errors.each{ action2(res, it) }
}

输出：

-- action1 --
error: ...
error: ...

Error when executing failure post condition:

如何解决这个问题？

Answer 1

按照这个答案中的建议，我将

action2

更改为：

def action2(res, line)
{
  println("-- action2 --")
  ...
}

异常消失了。
