Gradle 动态生成任务

Question

这是我第一次尝试使用 clojure，我试图在我的 build.gradle 文件中生成一些任务。我遇到了复杂性错误，例如:

* Where:

Build file '/Users/austin/Repositories/test/build.gradle' line: 47

* What went wrong:

A problem occurred evaluating root project 'test'. Cannot set the value of read-only property 'src' for task ':downloadDriverfirefox' of type de.undercouch.gradle.tasks.download.Download.

我相当肯定这只是我对 groovy 语言的缺乏经验，但我真的可以使用一些指示来指出我哪里出错了。

ext {
// The drivers we want to use
drivers = ["firefox", "chrome"]

driversSrc = [:]
driversSrc['firefox'] = 'https://github.com/mozilla/geckodriver/releases/download/v0.15.0/geckodriver-v0.15.0-macos.tar.gz'
driversSrc['chrome'] = 'https://chromedriver.storage.googleapis.com/2.29/chromedriver_mac64.zip'

driverDest = new File("${buildDir}/webdrivers")
}

import org.gradle.api.tasks.*
import de.undercouch.gradle.tasks.download.Download

driversSrc.each { driver, path ->
tasks.create(name: 'downloadDriver'+"${driver}", type: Download) {
    src = path
    dest ext.driverDest
    overwrite true
}
}

driversSrc.each {driver ->
tasks.create(name: 'unzipDriver'+"${driver}", dependsOn: 'downloadDriver'+"${driver}", type: Copy) {
    from zipTree(file('downloadDriver'+"${driver}").dest)
    into buildDir/'webdrivers'
}
}

我做过的事情:

清理 map 以存储数据

由于您正在使用此插件:https://github.com/michel-kraemer/gradle-download-task ，我必须确保正确使用任务

既然你有 tar，你必须使用 tarTree以及 zipTree

请试试这个:

buildscript {
  repositories {
    jcenter()
  }

  dependencies {
    classpath "de.undercouch:gradle-download-task:3.2.0"
  }
}

allprojects {
  repositories {
    jcenter()
  }
}
import de.undercouch.gradle.tasks.download.Download

apply plugin: "de.undercouch.download"

ext {
  driversSrc = [
          "firefox": "https://github.com/mozilla/geckodriver/releases/download/v0.15.0/geckodriver-v0.15.0-macos.tar.gz",
          "chrome" : "https://chromedriver.storage.googleapis.com/2.29/chromedriver_mac64.zip"
  ]
  driverDest = "${buildDir}/webdrivers"
}

driversSrc.each { driver, path ->
  def fileDest = new File(driverDest, new File(path).getName())

  tasks.create(name: "downloadDriver${driver}", type: Download) {
    src path
    dest fileDest
    overwrite true
  }

  tasks.create(name: "unzipDriver${driver}", dependsOn: "downloadDriver${driver}", type: Copy) {
    from path.endsWith("zip") ? zipTree(file(fileDest)) : tarTree(file(fileDest))
    into driverDest
  }
}

运行任务:

./gradlew unzipDriverfirefox unzipDriverchrome*
