Gradle動態生成任務

Question

這是我第一次嘗試使用clojure，並試圖在build.gradle文件中生成一些任務。我現在遇到複雜的錯誤，如：

*其中：

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

*出了什麼問題：

評估根項目「測試」時發生問題。 無法爲de.undercouch.gradle.tasks.download.Download類型的任務'downloadDriverfirefox'設置只讀屬性'src'的值。

我相當肯定這只是我的經驗不足與Groovy語言，但我真的可以使用一些指針，以我要去錯在何處。

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：

• 盪滌地圖存儲數據
• 由於您使用這個插件：https://github.com/michel-kraemer/gradle-download-task，我必須確保任務是正確使用
• 既然你有焦油，你必須使用tarTree以及zipTree

請試試這個：

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 
    } 
} 

要運行的任務：

./gradlew unzipDriverfirefox unzipDriverchrome*
