如何使用IntelliJ将外部库的源和javadoc添加到gradle中？

问题描述：

我已经使用IntelliJ和Gradle建立了一个Java项目。我的根项目中有一个build.gradle文件，我可以编译并运行我的应用程序。

I've set up a Java project with IntelliJ and Gradle. I have a build.gradle file in my root project and I can compile and run my app.

但是......我正在使用一个附带的Java库来源和javadoc zip文件。如果我在我的源代码中并想要从这个库中获取类或方法的声明，IntelliJ会调出 .class 文件而不是源 .java 文件。

However... I'm using a Java library which comes with a sources and javadoc zip file. If I'm in my source code and want to go to the declaration of a class or method from this library, IntelliJ brings up the .class file instead of the source .java file provided in the zip.

如何告诉gradle使用外部提供的源和javadoc拉链库？

How can I tell gradle to use the sources and javadoc zips provided with the external library?

答

我不确定你的库是否存储在maven存储库中。我认为是。

I'm not sure if your library is stored in a maven repository or not. I assume it is.

我知道将gradle项目导入IntelliJ的两种方法。第一个是IntelliJ的导入项目......向导，效果很好。但如果它们存在，它不会导入javadoc jar。至少我从未管理过它。

I know of two ways of importing a gradle project into IntelliJ. The first being the "Import Project..." wizard from IntelliJ which works nicely. But it does not import the javadoc jars if they exist. At least I never managed it.

第二种方法使用gradle 2.1中的idea插件。该插件为您生成项目。这样我就得到了javadoc。 build.gradle的完整工作示例：

The second method uses the idea plugin in gradle 2.1. The plugin generates the project for you. This way I got the javadoc inside. A fully working example for a build.gradle:

apply plugin: 'java'
apply plugin: 'idea'

sourceCompatibility = '1.7'
targetCompatibility = '1.7'

repositories {
    mavenCentral()
}

dependencies {
    compile group: 'org.apache.commons', name: 'commons-compress', version: '1.8.1'
    compile group: 'com.google.guava', name: 'guava', version: '18.0'

    testCompile group: 'junit', name: 'junit', version: '4.11'
    testCompile group: 'org.mockito', name: 'mockito-all', version: '1.8.5'
}

idea{
    project {
        languageLevel = '1.7'
    }
    module {
        downloadJavadoc = true // defaults to false
        downloadSources = true
    }
}

您可以调用 gradle cleanIdea idea 为英特尔创建项目liJ。

The you can call gradle cleanIdea idea which creates your project for IntelliJ.

如果你的图书馆没有存储在maven资料库中，你可以简单地在你上传它的地方建立一个连接点。这将允许您使用上述方法。

If your library is not stored in a maven repository you can simply put up a nexus where you upload it. This would allow you to use the method described above.
