gradle - 如何创建和使用 gradle 任务工厂函数

问题描述

我如何创建一个创建函数的函数，或者我应该要求调用它

// cant use this method see comment tagged ERROR further down
def webRollbackFactory(parentTask) {
  tasks.create(name: "webRollback.${parentTask.name}", type: Copy, dependsOn: [webBackup]) {
    onlyIf { patentTask.state.failure != null }
    from(zipTree("${webPublishPath}/../${getWebBackupName()}")) { include '*' }
    into webPublishPath
    doLast {
      println "\nwebRollback.${parentTask.name}.doLast"
    }
  }
}

// this task which do the same works with out problems
task webRollback_webPublish(type: Copy) {
  onlyIf { webPublish.state.failure != null }
  from(zipTree("${webPublishPath}/../${getWebBackupName()}")) { include '*' }
  into webPublishPath
  doLast {
    println "\nwebRollback.webPublish.doLast"
  }
}

task webPublish(type: com.ullink.Msbuild) {
  dependsOn msbuild, webBackup
  projectFile = "${webPublishProjectDir}/${webPublishProjectFileName}"
  targets = ['Publish']
  parameters = [PublishProfile: webPublishProfile]
  configuration = BUILD_TYPE
  parameters.maxcpucount
  doLast {
    println '\nwebPublish.doLast'
  }

  // ERROR: fails with: Could not find method webRollbackFactoy() for arguments [task ':webAccessTest'] on task ':webAccessTest' of type org.gradle.api.tasks.Exec.
  //finalizedBy webRollbackFactory(webPublish)

  // the version that works
  finalizedBy webRollback_webPublish
}

我在 Gradle 4.8

解决方案

你得到这个错误的原因是因为被评估的闭包没有找到在主文件中声明的函数。

尝试将您的函数更改为闭包作为变量引用，然后它应该可以工作。 webRollbackFactory = { parentTask -> tasks.create(name: "webRollback.${parentTask.name}", type: Copy, dependsOn: [webBackup]) { onlyIf { patentTask.state.failure != null } from(zipTree("${webPublishPath}/../${getWebBackupName()}")) { include '*' } into webPublishPath doLast { println "\nwebRollback.${parentTask.name}.doLast" } } }
