如何重构常见的Jenkins JobDSL代码？ [英] How to refactor common Jenkins JobDSL code?

问题描述

我有以下的JobDSL规范：

I have the following JobDSL spec:

job {
  steps {
    gradle('generateLock saveLock', '-PdependencyLock.includeTransitives=true', true) { node ->
      node / wrapperScript('${NEBULA_HOME}/gradlew')
    }
    gradle('check', '', true) { node ->
      node / wrapperScript('${NEBULA_HOME}/gradlew')
    }
  }
}

我想将通用代码重构成一个函数：

I'd like to refactor the common code, say, into a function:

def gradlew(String tasks, String options) {
  gradle(tasks, options, true) { node ->
    node / wrapperScript('${NEBULA_HOME}/gradlew')
  }
}

但是 gradle 函数在 gradlew 函数中是不可见的。什么是正确的做法？

But the gradle function isn't visible from within the gradlew function. What's the right way to do this?

推荐答案

大括号形成一个Groovy闭包。每个闭包都有一个方法调用指向的委托对象。代表可以通过代表属性进行访问。您可以将该委托传递给帮助函数以访问它的方法。

The curly brackets form a Groovy closure. Each closure has a delegate object to which method calls are directed. And the delegate can be accessed via the delegate property. You can pass that delegate to the helper function to get access to it's methods.

def gradlew(def context, String tasks, String options = '') {
  context.gradle(tasks, options, true) { node ->
    node / wrapperScript('${NEBULA_HOME}/gradlew')
  }
}
job {
  steps {
    gradlew(delegate, 'generateLock saveLock', '-PdependencyLock.includeTransitives=true')
    gradlew(delegate, 'check')
  }
}
