Gradle - 手动下载依赖项,锁定版本和更新依赖项

标签: java android gradle dependency-management

问题。

Gradle依赖管理如下:

  • 没有简单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)并下载替换旧版本的更新;
  • 依赖项工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;但是,成功编译项目不能依赖于连接到Internet,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的存在。

目标。

  • 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。

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用于编译项目测试源所需的依赖项。

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

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配置下载依赖关系:

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

testDownload配置下载依赖关系:

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工件提供。

这是使用android插件进行Gradle配置的示例:

...

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'])
}

为了使下载的依赖项(库/ etc版本到硬编码版本)锁定以使构建可重现,现在Gradle 4.8及以后版本,我们将内置“依赖锁定”支持。如果有人使用动态版本(Mmp / i)Major.minor.patch / interimBranch等(例如:4. +或3.1。+)或从二进制存储库工具中提取工件的版本范围,这将极大地帮助使构建重现性(例如:Artifactory / Nexus)。

使用Gradle版本4.8+的任何Gradle用户都应该开始使用此新功能。 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​​锁定功能已提供给Gradle社区,并通过Netflix Nebula的https://github.com/nebula-plugins/gradle-dependency-lock-pluginhttps://plugins.gradle.org/plugin/nebula.dependency-lock

提供给Gradle的FOSS插件提供
