將生成的第三方許可證複製到資產

Question

我想在Gradle中自動包含最新生成的第三方許可證。

配置：

• 搖籃2.x的
• 許可的gradle-插件0.11.0

代碼：

task beforeAssemble(dependsOn: assemble) << { 
    downloadLicenses.execute() 
    CopyToAssetsTask.execute() 
} 

task CopyToAssetsTask(type: Copy) { 
    description = 'Copies generated Third Party Licenses into assets' 
    from('$buildDir/reports/license') { 
     include('dependency-license.html') 
    } 
    into '$buildDir/intermediates/assets/debug/legal' 
} 

apply plugin: 'license' 

downloadLicenses { 
    includeProjectDependencies = true 
    reportByDependency = true 
    reportByLicenseType = true 
    dependencyConfiguration = "compile" 
} 

在命令行： gradlew clean assembleDebug

由此產生的APK不包括生成的文件，因爲我希望。我對Gradle很陌生，所以也許有一個簡單的解釋？

Answer 1

該解決方案爲我工作是答案略加修改的版本，約翰Stuyts公佈。

儘管存在一個限制：生成的報告將最終位於根資產文件夾中，而不是預期的子文件夾「legal」。

buildscript { 
     // ... 
     dependencies { 
      // ... 
      classpath 'nl.javadude.gradle.plugins:license-gradle-plugin:0.11.0' 
     } 
    } 

    android { 
    // ... 

    // Add the output folder of the license plug-in as 
    // a source folder for assets. 
     sourceSets { 
      main { 
       // ... 
       assets.srcDirs = ['src/main/assets', 'build/reports/license'] 
      } 
     } 
    } 

    downloadLicenses { 
     includeProjectDependencies = true 

     reportByDependency = true 
     reportByLicenseType = false 

     report.html.enabled = true 
     report.xml.enabled = false 

     dependencyConfiguration = "compile" 
    } 

    // Add a dependency after the project has been evaluated, because 
    // the Android plug-in does not add tasks "merge*Assets" to 
    // the project immediately. 
    project.afterEvaluate { 
     // Download the licenses when (actually: just before) the 
     // assets are merged (for both the "debug" and the 
     // "release" build types). 

     // If you add/change build types, you have to add to/change 
     // these task names. 
     mergeDebugAssets.dependsOn project.tasks.getByName('downloadLicenses') 
     mergeReleaseAssets.dependsOn project.tasks.getByName('downloadLicenses') 
    } 

Answer 2

嘗試改變CopyToAssetsTask到：

task CopyToAssetsTask << { 
    copy { 
     description = 'Copies generated Third Party Licenses into assets' 
     from('$buildDir/reports/license') { 
      include('dependency-license.html') 
     } 
     into '$buildDir/intermediates/assets/debug/legal' 
    } 
} 

，因爲現在，你複製在配置階段完成。

首先一些觀察。解決方案在最後：

• 你還在思考程序化：告訴Gradle在什麼時候做什麼（即你在做什麼beforeAssemble）。使用任務圖：指定任務的依賴關係（參見下面的一些可能性）。當你需要輸出一個任務時，只需要問Gradle來執行那個任務，Gradle就會找出那個任務依賴的傳遞任務。它將執行所有這些任務：只執行一次，並按正確的順序執行。
• 此聲明：task beforeAssemble(dependsOn: assemble)，沒有意義。您希望任務在assemble之前運行，但取決於assemble您取得了相反的結果：assemble將在beforeAssemble之前運行。

如何指定依賴關係？有多種選擇：

• 使用直接依賴關係：dependsOn。
• 參考任務inputs中的其他任務。
• 設置任務的選項，該選項將自動創建依賴關係。例如：如果Copy任務的from屬性設置爲其他任務的輸出，則Copy任務將自動將該其他任務添加爲輸入。

這是解決方案。您希望兩個實現兩件事：

• 生成期間（在某個特定點）生成許可證信息。
• 將許可證信息包含在檔案中。

添加到您的構建腳本：

android { 
    // ... 

    // Add the output folder of the license plug-in as 
    // a source folder for resources. 
    sourceSets { 
     main { 
      resources { 
       srcDir 'build/reports/license' 
      } 
     } 
    } 
} 

downloadLicenses { 
    includeProjectDependencies = true 
    reportByDependency = true 
    reportByLicenseType = true 
    dependencyConfiguration = "compile" 
} 

// Add a dependency after the project has been evaluated, because 
// the Android plug-in does not add tasks "generate*Resources" to 
// the project immediately. 
project.afterEvaluate { 
    // Download the licenses when (actually: just before) the 
    // resources are generated (for both the "debug" and the 
    // "release" build types). 

    // If you add/change build types, you have to add to/change 
    // these task names. 
    generateDebugResources.dependsOn tasks['downloadLicenses'] 
    generateReleaseResources.dependsOn tasks['downloadLicenses'] 
}

在我的項目（3.4.1的gradle），它是這樣工作在Android的 「模塊：應用程序」 文件的gradle：

plugins { 
    id "com.github.hierynomus.license" version "0.14.0" 
} 

license { 
    include "**/*.java" 
    strictCheck = false 
    ignoreFailures = true 
    skipExistingHeaders = true 
} 

downloadLicenses { 
    includeProjectDependencies = true 
    reportByDependency = true 
    reportByLicenseType = false 
    dependencyConfiguration = "compile" 
    licenses = [ 
     (group('com.android.support')) : license('Apache License, Version 2.0', 'http://www.apache.org/licenses/LICENSE-2.0'), 
     (group('com.android.support.constraint')) : license('Apache License, Version 2.0', 'http://www.apache.org/licenses/LICENSE-2.0'), 
     (group('com.google.firebase')) : license('Apache License, Version 2.0', 'http://www.apache.org/licenses/LICENSE-2.0'), 
     (group('com.google.android')) : license('Apache License, Version 2.0', 'http://www.apache.org/licenses/LICENSE-2.0'), 
     (group('com.google.android.gms')) : license('Apache License, Version 2.0', 'http://www.apache.org/licenses/LICENSE-2.0') 
] 
} 

apply plugin: 'com.android.application' 

android { 
    compileSdkVersion 25 
    buildToolsVersion "25.0.2" 

    defaultConfig { 
    ... 
    } 

    sourceSets { 
     main { 
      assets.srcDirs = ['src/main/assets', 'build/licenses/'] 
     } 
    } 

    buildTypes { 
    ... 
    } 
} 

dependencies { 
    compile 'com.android.support:appcompat-v7:25.3.1' 
    compile 'com.android.support:multidex:1.0.1' 
    compile 'com.android.support:support-v4:25.3.1' 
    compile 'com.android.support:design:25.3.1' 
    ... 
} 

task copyLicenseReport(type: Copy) { 
    from('build/reports/license') { 
    include '**/*.html' 
    include '**/*.xml' 
    } 
    into 'build/licenses/thirdPartyLicenses' 
} 

project.afterEvaluate { 
    copyLicenseReport.dependsOn project.tasks.getByName('downloadLicenses') 
    preBuild.dependsOn copyLicenseReport 
}
