Gradle-下载依赖项，锁定版本并手动更新依赖项

Gradle依赖管理使得：

  • 没有简便的方法来检查依赖项更新的可用性（仅使用某些第三方插件，如ben-manes / gradle-versions-plugin）并下载更新以替换旧版本；

  • 从远程存储库下载依赖项工件，然后将其存储在gradle缓存中，并在后续构建中重用；但是项目的成功编译必须不依赖于与Internet的连接，远程存储库的可用性以及这些存储库中特定版本的依赖项。

  • 在VCS中下载并存储所有依赖项工件；

  • 手动检查这些依赖项的更新并下载它们。

回答：

我的解决方案适用于使用java或android插件进行Gradle配置。

java插件定义compile和testCompile配置。

compile用于编译项目生产源所需的依赖项。testCompile用于编译项目测试源所需的依赖项。

让我们在中定义自己的配置build.gradle：

configurations {
    download
    testDownload
}

接下来让我们创建目录：

  • libs/compile/downloaded是download将存储依赖项的位置；

  • libs/testCompile/downloaded是testDownload将存储依赖项的位置。

接下来，我们定义几个任务。

从download配置中删除依赖项：

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

从testDownload配置中删除依赖项：

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

从download配置下载依赖项：

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

从testDownload配置下载依赖项：

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

执行上述所有任务以更新依赖关系：

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

接下来，我们定义依赖项：

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

然后，我们告诉哪里compile和testCompile配置应使用用于编译的依赖项。

    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经下载的依赖项：

./gradlew updateDependencies

如果您使用的是android插件，则还可以为androidTestDownload在Android设备上编译和运行测试所需的依赖项添加配置。还可以将某些依赖项作为aar工件提供。

这是使用android插件配置Gradle的示例：

...
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'])
}
