java - Gradle - 手动下载依赖、锁定版本和更新依赖

Question

问题。

Gradle 依赖管理是这样的:

• 没有简单的方法来检查依赖项更新的可用性(只能使用一些第三方插件，如 ben-manes/gradle-versions-plugin )和下载更新以替换旧版本；
• 依赖项 Artifact 从远程存储库下载，然后存储在 gradle 缓存中，并在后续构建中重复使用；但项目的成功编译不能依赖于与 Internet 的连接、远程存储库的可用性以及这些存储库中依赖项的特定版本的存在。

目标。

• 下载所有依赖项并将其存储在 VCS 中；
• 手动检查这些依赖项的更新并下载它们。

我的解决方案适用于使用 java 或 android 插件的 Gradle 配置。

java 插件定义了compile 和testCompile 配置。compile 用于编译项目的生产源代码所需的依赖项。 testCompile 用于编译项目测试源所需的依赖。

让我们在build.gradle中定义我们自己的配置:

configurations {
    download
    testDownload
}

接下来让我们创建目录:

• libs/compile/downloaded 是存放download依赖的地方；
• libs/testCompile/downloaded 是存储 testDownload 依赖项的地方。

接下来我们定义几个任务。

从下载配置中删除依赖:

task cleanDownloadedDependencies(type: Delete) {
    delete fileTree('libs/compile/downloaded')
}

从testDownload配置中删除依赖:

task cleanDownloadedTestDependencies(type: Delete) {
    delete fileTree('libs/testCompile/downloaded')
}

从download配置下载依赖:

task downloadDependencies(type: Copy) {
    from configurations.download
    into "libs/compile/downloaded/"
}

从testDownload配置下载依赖:

task downloadTestDependencies(type: Copy) {
    from configurations.testDownload
    into "libs/testCompile/downloaded/"
}

执行上述所有任务以更新依赖项:

task updateDependencies {
    dependsOn cleanDownloadedDependencies, cleanDownloadedTestDependencies, downloadDependencies, downloadTestDependencies
}

接下来我们定义我们的依赖:

dependencies {
    download(
            'com.google.code.gson:gson:+',
            'joda-time:joda-time:+',
    )
    testDownload(
            'junit:junit:+'
    )

然后我们告诉 compile 和 testCompile 配置应该在哪里获取用于编译的依赖项。

    compile fileTree(dir: 'libs/compile', include: '**/*.jar')
    testCompile fileTree(dir: 'libs/testCompile', include: '**/*.jar')
}

现在您可以下载或更新已下载的依赖项:

./gradlew updateDependencies

如果您使用的是 android 插件，那么您还可以为在 Android 设备上编译和运行测试所需的依赖项添加 androidTestDownload 配置。此外，一些依赖项可以作为 aar Artifact 提供。

这是使用 android 插件的 Gradle 配置示例:

...

repositories {

    ...

    flatDir {
        dirs 'libs/compile', 'libs/compile/downloaded',
                'libs/testCompile', 'libs/testCompileDownloaded',
                'libs/androidTestCompile', 'libs/androidTestCompile/downloaded'
    }
}

configurations {
    download
    testDownload
    androidTestDownload
}

android {
    ...
}

dependencies {
    download(
            'com.android.support:support-v4:+',
            'com.android.support:appcompat-v7:+',
            'com.google.android.gms:play-services-location:+',
            'com.facebook.android:facebook-android-sdk:+',
            'com.vk:androidsdk:+',
            'com.crashlytics.sdk.android:crashlytics:+',
            'oauth.signpost:signpost-core:+',
            'oauth.signpost:signpost-commonshttp4:+',
            'org.twitter4j:twitter4j-core:+',
            'commons-io:commons-io:+',
            'com.google.code.gson:gson:+',
            'org.jdeferred:jdeferred-android-aar:+'
    )
    compile fileTree(dir: 'libs/compile', include: '**/*.jar')
    testCompile fileTree(dir: 'libs/testCompile', include: '**/*.jar')
    androidTestCompile fileTree(dir: 'libs/androidTestCompile', include: '**/*.jar')
}


task cleanDownloadedDependencies(type: Delete) {
    delete fileTree('libs/compile/downloaded')
}

task cleanDownloadedTestDependencies(type: Delete) {
    delete fileTree('libs/testCompile/downloaded')
}

task cleanDownloadedAndroidTestDependencies(type: Delete) {
    delete fileTree('libs/androidTestCompile/downloaded')
}

task downloadDependencies(type: Copy) {
    from configurations.download
    into 'libs/compile/downloaded/'
}

task downloadTestDependencies(type: Copy) {
    from configurations.testDownload
    into 'libs/testCompile/downloaded/'
}

task downloadAndroidTestDependencies(type: Copy) {
    from configurations.androidTestDownload
    into 'libs/androidTestCompile/downloaded/'
}

task updateDependencies {
    dependsOn cleanDownloadedDependencies, cleanDownloadedTestDependencies, cleanDownloadedAndroidTestDependencies, downloadDependencies, downloadTestDependencies, downloadAndroidTestDependencies
}

fileTree(dir: 'libs/compile', include: '**/*.aar')
        .each { File file ->
    dependencies.add("compile",
            [name: file.name.lastIndexOf('.').with { it != -1 ? file.name[0..<it] : file.name }, ext: 'aar'])
}

fileTree(dir: 'libs/testCompile', include: '**/*.aar')
        .each { File file ->
    dependencies.add("testCompile",
            [name: file.name.lastIndexOf('.').with { it != -1 ? file.name[0..<it] : file.name }, ext: 'aar'])
}

fileTree(dir: 'libs/androidTestCompile', include: '**/*.aar')
        .each { File file ->
    dependencies.add("androidTestCompile",
            [name: file.name.lastIndexOf('.').with { it != -1 ? file.name[0..<it] : file.name }, ext: 'aar'])
}
