1: Maven command to download source code and javadocs
When using Maven in the IDE, if you want to see the source code and javadoc of the classes in the referenced jar package, you need to download the source code through the maven command, and then import it. This purpose can be easily achieved through the mvn command:
mvn dependency:sources mvn dependency:resolve -Dclassifier=javadoc
Command usage: first enter the corresponding pom.xml directory, and then execute the above command:
The first command is to try to download the source code of the files that are depended on in pom.xml.
The second command: is to try to download the corresponding javadocs
But it is possible that some files do not have source code or javadocs
2: Add via configuration file
Open the maven configuration file setting.xml file (.../.m2/settings.xml) and add the following configuration:
<profiles>
<profile>
<id>downloadSources</id>
<properties>
<downloadSources>true</downloadSources>
<downloadJavadocs>true</downloadJavadocs>
</properties>
</profile>
</profiles>
<activeProfiles>
<activeProfile>downloadSources</activeProfile>
</activeProfiles>
3: Configure eclipse
