在 gradle 中，我有以下 build.gradle，它导致很多 JAR 被复制到“sources”文件夹，但实际上只有 jersey-media-moxy-2.22.2-sources.jar 包含源代码:

defaultTasks 'run'

repositories {
    mavenCentral()
}

configurations {
    sources {
        description = 'sources download'
        transitive = true
    }
    copysource {
        extendsFrom sources
    }
}

dependencies {
    sources group: 'org.glassfish.jersey.media', name: 'jersey-media-moxy', version: '2.22.2', classifier: 'sources'
}


task copySources(type: Copy) {
    println 'Copying dependencies to sources directory'
    into "sources/"
    from configurations.copysource
}

task run (dependsOn: ['copySources']){
    println 'Downloading JARs'
}

run << {
    println 'Downloads complete. Finished.'
}

如何修改构建以获得所有源代码(包括传递/依赖源)？我不想要非源 jar 。我不明白为什么不传递地应用分类器，所以请消除我的误解。

另外，我知道这不是使用 gradle 的最佳方式。在我们迁移构建系统之前，这是(部分)临时步骤。

最佳答案

首先我们要提醒它

我们需要先在idea的模块部分或eclipse classpath部分添加两件事

idea {
    module {
            //if you love browsing Javadoc
            downloadJavadoc = true

            //if you love reading sources :)
            downloadSources = true
    }
}

或

apply plugin: 'java'
apply plugin: 'eclipse'

eclipse {
    classpath {
       downloadSources=true
       downloadJavadoc = true
    }
}

资源链接:

1. https://docs.gradle.org/current/dsl/org.gradle.plugins.ide.idea.model.IdeaModule.html
2. Dependency Management

其次，

我们需要从存储库部分删除 mavenLocal() 部分，存储库将放在最上面的部分。你已经做到了。

repositories {
    mavenLocal() // remove this
    mavenCentral()
}

第三，

有时您在 Eclipse WTP 中看不到源代码，尽管它们是通过 gradle 下载的。在这种情况下，您需要手动将 Web 应用程序库推送到构建路径的底部。 为了解决，你需要遵循

1. 右键单击您的项目，然后选择“Build Path”-->“Configure 构建路径”;
2. 选择“订购并导出”
3. 选择“Web App Libraries”，点击“底部”按钮，然后点击“Web 应用程序库”将在底部；

然后将其放入 Gradle Eclipse 插件中(这样您就不需要每次都手动执行): Why is Eclipse not attaching 3rd party libs source files to a WTP-faceted Gradle project?

更新:

我想给你更新，现在我可以下载所有 javadocs 和源 jar 文件。但我无法将它们复制到源文件夹中。我成功尝试下载 javadocs 和源 jar 如下:

build.gradle 文件如下:

group 'com.waze'
version '1.0-SNAPSHOT'

apply plugin: 'java'
apply plugin: 'eclipse'

sourceCompatibility = 1.8

repositories {
    mavenCentral()
}

configurations {
    sources {
        description = 'sources download'
        transitive = true
    }
    copysource {
        extendsFrom sources
    }
}

eclipse {
    classpath {
       downloadSources = true
       downloadJavadoc = true
    }
}

dependencies {
    compile group: 'org.glassfish.jersey.media', name: 'jersey-media-moxy', version: '2.22.2'
    sources group: 'org.glassfish.jersey.media', name: 'jersey-media-moxy', version: '2.22.2', classifier: 'javadoc'
    sources group: 'org.glassfish.jersey.media', name: 'jersey-media-moxy', version: '2.22.2', classifier: 'sources'
}

task copySources(type: Copy) {
    println 'Copying dependencies to sources directory'
    into "sources/"
    from configurations.copysource
}

task run (dependsOn: ['copySources']){
    println 'Downloading JARs'
}

run << {
    println 'Downloads complete. Finished.'
}

命令提示符下的输出:正在下载javadocs和sources jar文件
