在IntelliJ IDEA中，您可以在导入时通过打开“自动下载源”选项自动下载工件源:

设置→构建、执行、部署→构建工具→Maven→导入

在eclipse中-点击项目然后:

.

要下载某些特定的源代码或javadoc，我们需要包括GroupIds -它是一个逗号分隔的值，如下所示

mvn dependency:sources -DincludeGroupIds=com.jcraft,org.testng -Dclassifier=sources

注意，分类器不是用逗号分隔的，要下载javadoc，我们需要使用分类器javadoc再次运行上述命令

mvn dependency:sources -DincludeGroupIds=com.jcraft,org.testng -Dclassifier=javadoc

你可以，如果他们被上传。通常它们被称为“frameworkname-version-source(s)”

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。

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
