maven下载源码和java docs

方法一：

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.

方法二：

Open your settings.xml file (~/.m2/settings.xml). Add a section with the properties added. Then make sure the activeProfiles includes the new profile.

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

<activeProfiles>
    <activeProfile>downloadSources</activeProfile>
</activeProfiles>
