Gradle动态生成任务

Question

这是我第一次尝试使用clojure，并试图在build.gradle文件中生成一些任务。我现在遇到复杂的错误，如：

*其中：

构建文件 '/Users/austin/Repositories/test/build.gradle' 行：47

*出了什么问题：

评估根项目“测试”时发生问题。 无法为de.undercouch.gradle.tasks.download.Download类型的任务'downloadDriverfirefox'设置只读属性'src'的值。

我相当肯定这只是我的经验不足与Groovy语言，但我真的可以使用一些指针，以我要去错在何处。

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' 
} 
} 

Answer 1

我所做的事情：

• 荡涤地图存储数据
• 由于您使用这个插件：https://github.com/michel-kraemer/gradle-download-task，我必须确保任务是正确使用
• 既然你有焦油，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 
    } 
} 

要运行的任务：

./gradlew unzipDriverfirefox unzipDriverchrome*
