java Gradle下载源依赖项

1 年 Questions & Answers

在gradle中，我有以下构建。gradle，这导致许多jar被复制到“sources”文件夹，但只有jersey-media-moxy-2.22.2-sources。jar实际上包含源代码：

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（包括可传递源/依赖源）？我不想要非源jar。我不明白为什么分类器不能传递应用，所以请澄清我的误解

而且，我知道这不是使用gradle的最佳方式。在迁移构建系统之前，这是一个临时步骤（部分）

  1. # 1 楼答案

    我发现的方法是遍历可传递依赖项树，分别下载每个依赖项的源代码。这远非理想，但它确实有效

    请注意，在声明依赖项时，不再需要在依赖项上指定分类器

    plugins {
    id 'java'
}

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'
}


Dependency toSourceDependency(ResolvedDependency dependency) {
    dependencies.create([
            group     : dependency.module.id.group,
            name      : dependency.module.id.name,
            version   : dependency.module.id.version,
            classifier: 'sources',
            transitive: false
    ])
}

task('run') {
    doLast {
        configurations.copysource
                .resolvedConfiguration
                .lenientConfiguration
                .allModuleDependencies
                .each { dependency ->
                    def sourceResources = configurations
                            .detachedConfiguration([toSourceDependency(dependency)] as Dependency[])
                            .resolvedConfiguration
                            .lenientConfiguration
                            .getFiles(Specs.SATISFIES_ALL)

                    copy {
                        from sourceResources
                        into 'sources/'
                    }
                }
    }
}

    Gradle没有任何与依赖项的“源”配置相关的APIChapter 7. Dependency Management Basics

    答案也独立于集成开发环境。如果尚未应用特定的IDE插件，则需要应用该插件

    IntelliJ

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

    日食

    apply plugin: 'eclipse'
eclipse {
    classpath {
        downloadJavadoc = true
        downloadSources = true
    }
}
  3. # 3 楼答案

    首先，我们必须提醒它

    我们需要在idea's module section或eclipse classpath section中首先添加两个内容

    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，存储库将被放置在最上面的部分。你已经做到了

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

    第三，

    有时您在EclipseWTP中看不到源代码，尽管它们是由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。 为了解决这个问题，你需要遵循

    1. 右键单击项目，然后选择“构建路径”>；“配置 构建路径”
    2. 选择“订单和导出”
    3. 选择“Web应用程序库”，单击“底部”按钮，然后单击“Web应用程序库” 应用程序库”将位于底部

    要将这一点输入Gradle Eclipse插件（因此您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?

    归功于@jasop

    更新：

    我想给你们更新，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。下面给出了我下载javadocs和jar源代码的成功尝试：

    build.gradle文件如下所示：

    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.'
}

    命令提示符中的输出：下载javadocs和源jar文件
