如果您正在使用Eclipse，我建议同时下载源代码和第三方库的Javadocs。

右键点击项目和下载两个截图如下。

下载Javadocs意味着通常可以从第三方库中获得方法的上下文帮助，其中包含有用的参数描述等。如果你不太了解图书馆，这是很重要的。在某些情况下，我发现当源代码不可用时，Javadocs是可用的。

Maven Micro-Tip: Get sources and Javadocs When you're using Maven in an IDE you often find the need for your IDE to resolve source code and Javadocs for your library dependencies. There's an easy way to accomplish that goal. mvn dependency:sources mvn dependency:resolve -Dclassifier=javadoc The first command will attempt to download source code for each of the dependencies in your pom file. The second command will attempt to download the Javadocs. Maven is at the mercy of the library packagers here. So some of them won't have source code packaged and many of them won't have Javadocs. In case you have a lot of dependencies it might also be a good idea to use inclusions/exclusions to get specific artifacts, the following command will for example only download the sources for the dependency with a specific artifactId: mvn dependency:sources -DincludeArtifactIds=guava

IntelliJ idea的maven idea插件允许您指定是否应该解析和下载源代码和java文档

mvn idea:idea -DdownloadSources=true -DdownloadJavadocs=true

NetBeans, Context-Click

在NetBeans 8的maven驱动项目中，只需上下文单击感兴趣的依赖项的jar文件列表项。选择“下载源”。稍等片刻，NetBeans将自动下载并安装源代码(如果可用的话)。

类似地，您可以选择Download Javadoc以在本地安装文档。然后，您可以在编辑器中上下文单击一些代码并选择查看JavaDoc。
