Gradle-下载依赖项、锁定版本并手动更新依赖项

Question

问题。

分级依赖项管理是这样进行的：

• 检查依赖更新的可用性（仅使用一些第三方插件，如Ben-Manes/Gradle-Versions-Plugin)，并下载替换旧版本的更新是不容易的；
• 依赖项构件从远程存储库下载，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。

configurations {
    download
    testDownload
}

null

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

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

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/"
}

执行以上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关系：

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

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

./gradlew updateDependencies

...

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:+',

            '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) {

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'])
}
