Generally speaking, there are three types of package, *.jar , *-sources.jar and *-javadoc.jar, for each artifact in remote maven repository, but mvn only resolves the jar dependencis while compiling the source code.
Could someone tell me how to resolve *-sources.jar and *-javadoc.jar from remote repository by mvn.
I believe the question on how to get the javadoc was answered on a related thread here: Get source JARs from Maven repository
It's mvn dependency:resolve -Dclassifier=javadoc
Strictly speaking, the others are not dependencies, so there is nothing to "resolve".
If you want to retrieve that jar, you can just download [repo-url]/[groupId]/[artifactId]/[version]/[artifactId]-[version]-sources.jar ... most repositories can be navigated through the directory structure, so you should be able to find it simply.
You can also try
mvn dependency:get groupId:artifactId:version:jar:sources -Dtransitive=false
mvn dependency:sources can download the source attachments from remote maven repository if exists. See http://maven.apache.org/plugins/maven-dependency-plugin/usage.html.
But how to get the javadoc?
