How Maven Associates Source

Method One: Maven command

When using Maven in the IDE, if you want to see the source code and Javadoc for the class in the referenced Jar pack and then introduce it, you can easily achieve this by using the MVN command:
MVN dependency:sources
MVN Dependency:resolve-dclassifier=javadoc
Command usage: First go to the appropriate Pom.xml directory, and then execute the above command:
The first command is the source code that attempts to download the files that are dependent on the pom.xml.
Second command: Try to download the corresponding Javadocs
But it is possible that some files have no source code or Javadocs
Reference Method Two: Modify the configuration file Settings.xml

<profiles> <profile> <id>downloadSources</id> <properties> &                    Lt;downloadsources>true</downloadsources> <downloadJavadocs>true</downloadJavadocs> </properties> </profile> </profiles> <activeProfiles> <act Iveprofile>downloadsources</activeprofile> </activeProfiles>

method Three: Configuring in Eclipse

method Four: Select in the Project
