Gradle正在下载源代码依赖项。

在gradle中，我有以下build.gradle文件，它会导致许多JAR文件被复制到“sources”文件夹中，但只有jersey-media-moxy-2.22.2-sources.jar实际包含源代码：
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.'
}

我该如何修改构建过程，以便获取所有源代码（包括传递性/依赖项源代码）？我不想要非源码的jar包。我不明白为什么分类器不能被传递使用，请帮我澄清一下我的误解。

另外，我知道这不是使用gradle的最佳方式。这只是一个临时步骤，直到我们迁移构建系统。

我也非常渴望知道这个问题的答案。请接受我对迄今为止完全无用的答案的同情！ - Tom Anderson

首先我们需要提醒一下

在IDEA的模块部分或Eclipse的classpath部分，我们需要先添加两个东西。

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

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

或者
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. 依赖管理

其次，

我们需要从存储库部分中移除 mavenLocal() 部分，并将存储库放置在最顶部的部分。你已经完成了这一步。

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

第三步：

有时候，即使使用gradle已经下载了源代码，但在Eclipse WTP中仍然看不到源文件。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。

解决方法如下：

  1. 右键单击项目，然后选择“Build Path”-->“Configure Build Path”；
  2. 选择“Order and export”；
  3. 选择“Web App Libraries”，点击“Bottom”按钮，然后“Web App Libraries”将会处于底部位置；

为了让Gradle Eclipse插件自动执行上述操作（这样每次都不需要手动进行），请参考以下链接：Why is Eclipse not attaching 3rd party libs source files to a WTP-faceted Gradle project?

更新：

我想告诉你们一个最新进展：现在我可以下载所有的javadoc和源代码jar文件了。但是我无法将它们复制到源代码文件夹中。以下是我成功尝试下载javadoc和源代码jar文件的步骤：

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.'
}

在命令提示符中输出：下载javadocs和源jar文件

你运行了我的示例吗？关键是要将依赖项复制到“sources”文件夹中，但这并没有做到。我不想将源JAR附加到Eclipse构建路径JAR中。 - KyleM
@KyleM，现在我可以下载所有的“依赖Javadocs”和“源jar”文件。但我没有复制它。现在我正在尝试将其复制到“源”文件夹中。如果我成功了，我会告诉你的。如果你成功了，请分享一下。谢谢。 - SkyWalker
谢谢。也许如果编译依赖组被复制到源文件夹中，那么依赖的JAR文件也会被复制。我还没有尝试过，但一旦我上班了就会去尝试。 - KyleM
我给你奖励是因为你尝试了，虽然这并没有回答问题，因为它没有将任何可传递的源文件复制到文件夹中。 - KyleM
@KyleM 你有任何答案吗？如果你有答案，请分享一下。我对此非常感兴趣。非常感谢。 - SkyWalker
不好意思，我还不知道答案。我猜想通过学习Eclipse插件，我可以编写出一个答案。如果我能够做到，我会告诉你的。 - KyleM

Gradle没有与依赖项的“source”配置相关的任何API。第7章 依赖管理基础

这个答案也独立于集成开发环境。如果您还没有应用特定的IDE插件，您需要先应用它。

IntelliJ

apply plugin: 'idea'
idea{
    module {
        downloadJavadoc = true // defaults to false
        downloadSources = true
    }
}

Eclipse

apply plugin: 'eclipse'
eclipse {
    classpath {
        downloadJavadoc = true
        downloadSources = true
    }
}
Gradle的依赖配置如上所示。文档明确提到支持分类器，也许我没有理解如何使用分类器。无论如何，Eclipse插件都无法解决这个问题。 - KyleM
@KyleM 我没有看到sources作为依赖项的配置。从页面上，你只能有compile, runtime, testCompile, testRuntime, compileOnly (gradle 2.13)。我现在明白你所说的关于配置的问题了。但我相当确定你使用的方式是不正确的。 - Mr00Anderson
那是不正确的。您可以随意命名依赖配置。您所指的配置是由Java插件定义的标准配置。我发布的示例如果使用“compile”和“runtime”将具有相同的输出。https://docs.gradle.org/current/userguide/artifact_dependencies_tutorial.html#configurations。不过还是谢谢，感谢您的回复。 - KyleM

我发现的方法是遍历传递依赖关系的树，并单独下载每个依赖项的源代码。虽然不太理想，但它能够工作。
请注意，在声明依赖关系时，您不再需要指定分类器。
