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

在eclipse中-点击项目然后:

.

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。

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

下载任何工件使用

mvn dependency:get -Dartifact=groupId:artifactId:version:packaging:classifier

对于Groovy源代码，这将是

mvn dependency:get -Dartifact=org.codehaus.groovy:groovy-all:2.4.6:jar:sources

对于Groovy的javadoc，您将使用

mvn dependency:get -Dartifact=org.codehaus.groovy:groovy-all:2.4.6:jar:javadoc

这将把给定的工件放到本地Maven存储库中，通常是$HOME/.m2/存储库。

Dependency:sources只下载项目依赖项的源代码，不下载插件源代码，也不下载插件内部定义的依赖项的源代码。

为了调试，你也可以使用“Java反编译器”，如:JAD，并在运行中反编译源代码(尽管生成的源代码永远不会与原始源代码相同)。然后将JAD作为插件安装到Eclipse或您喜欢的IDE中。
