Maven命令下载源码和javadocs

1：Maven命令下载源码和javadocs

mvn dependency:sources

mvn dependency:resolve -Dclassifier=javadoc

mvn eclipse:eclipse -DdownloadSources -DdownloadJavadocs 

mvn dependency:resolve -Dclassifier=javadoc
mvn dependency:resolve -Dclassifier=sources

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

2：通过配置文件添加setting.xml

<profiles>  
<profile>  
    <id>downloadSources</id>  
    <properties>  
        <downloadSources>true</downloadSources>  
        <downloadJavadocs>true</downloadJavadocs>             
    </properties>  
</profile>  
</profiles>  
  
<activeProfiles>  
  <activeProfile>downloadSources</activeProfile>  
</activeProfiles>
