Maven - Always Download Sources and Javadocs

Maven – Always download sources and javadocs

Open your settings.xml file ~/.m2/settings.xml (create it if it doesn't exist). Add a section with the properties added. Then make sure the activeProfiles includes the new profile.

<settings>

   <!-- ... other settings here ... -->

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

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

Edit: As mentioned by Jingguo Yao, this works with Eclipse IDE only - the same can also be configured in your IDE of choice. In Elcipse via Window -> Preferences -> Maven menu, though this probably has to done at every workspace level and for fresh Eclipse installations.

Alternatively configure the maven-dependency-plugin in your pom.xml in a separate profile and run it as required - keeping it in the main build will lead to build times (needlessly elongating (not to mention space) at places like your build nodes that don't need either sources or java docs. Preferable this should configured in some org or division parent pom.xml, otherwise it has be repeated everywhere in different places

Disabling Download sources and javadoc in eclipse

Someone already filled a bug at Eclipse:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=576112

Apparently, it's fixed in M2E, but not yet released. Though, you can update on the latest snapshot as explained here:
https://github.com/eclipse-m2e/m2e-core/issues/252#issuecomment-926379620

It solved the issue for me.

Until the release in Eclipse, you must add this update-site:
https://download.eclipse.org/technology/m2e/snapshots/1.18.3/latest/

Accoriding to @Nis this is now released in the standard Eclipse update-site, so you don't need to add the preceding update-site anymore

How to download sources for a jar with Maven?

2020 Update:

The maven dependency plugin should be used whit the dependency:sources goal:

  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-dependency-plugin</artifactId>
    <version>3.1.1</version>
    <executions>
      <execution>
        <id>download-sources</id>
        <goals>
          <goal>sources</goal>
        </goals>
        <configuration>
        </configuration>
      </execution>
    </executions>
  </plugin>

This can also be run from the command line as:

mvn dependency:sources -Dsilent=true

Executing mvn dependency:sources will force maven to download all sources of all jars in the project, if the sources are available (are uploaded in the repository where the artifact is hosted). If you want to download javadoc the command is mvn dependency:resolve -Dclassifier=javadoc

Deprecated:

<properties>
  <downloadSources>true</downloadSources>
  <downloadJavadocs>true</downloadJavadocs>
</properties>

Eclipse|Maven: Can't download source code of jar package?

I believe that you are using an embedded version of maven.

There are two items you need to check:

1. Check if the options in Eclipse are selected as screen bellow

The second approach is to select an external installation of maven.

Take a look in the screenshot bellow. I'm using an external installation of maven.

In the second approach maven will read the settings.xml of external installation.
