Gradle - 手动下载依赖、锁定版本和更新依赖

Gradle - download dependencies, lock versions and update dependencies manually

问题。

Gradle 依赖管理是这样的:

目标。

我的解决方案适用于使用 javaandroid 插件的 Gradle 配置。

java 插件定义了 compiletestCompile 配置。 compile 用于编译项目的生产源所需的依赖项。 testCompile是编译项目测试源码需要的依赖。

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

接下来我们定义几个任务。

download 配置中删除依赖项:

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

testDownload 配置中删除依赖项:

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

download 配置下载依赖项:

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

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
}

接下来我们定义依赖项:

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

然后我们告诉 compiletestCompile 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

如果您正在使用 android 插件,那么您还可以为 Android 设备上的编译和 运行 测试所需的依赖项添加 androidTestDownload 配置。还可以将一些依赖项作为 aar 工件提供。

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'])
}

对于下载依赖项的锁定版本(库/等版本到硬编码版本)以使构建可重现,现在 Gradle 4.8 及更高版本,我们将内置 "dependency lock" 支持。如果有人使用动态版本 (M.m.p/i) Major.minor.patch/interimBranch 等(例如:4.+ 或 3.1.+),这将极大地帮助构建可重现或从二进制存储库工具中提取工件的版本范围(例如:Artifactory / Nexus)。

任何使用 Gradle 4.8+ 版本的 Gradle 用户都应该开始使用这个新功能。 https://docs.gradle.org/4.8/userguide/dependency_locking.html 对于 Gradle 4.8 发行说明:https://docs.gradle.org/4.8/release-notes.html

过去,此依赖​​项锁定功能已提供给 Gradle 社区,并通过 Netflix Nebula https://github.com/nebula-plugins/gradle-dependency-lock-plugin and https://plugins.gradle.org/plugin/nebula.dependency-lock
