有没有办法让Maven为本地仓库的所有依赖项安装javadocs？

Question

By running mvn dependency:sources I can force maven to resolve all dependencies in my project, download the sources, and install them into my local repo.

Is there something that does the same thing with my dependencies' JavaDocs? Ie grab them from upstream repos and install them into my local repo.

Answer 1

There is a way to do it with the eclipse:eclipse mojo using the downloadJavadocs parameter.

mvn eclipse:eclipse -DdownloadJavadocs

And if you don't use eclipse, just do

mvn eclipse:clean 

afterwards.

It's a hack, I know, but it works.

Actually, dependency:sources pretends to be configurable through the classifier and type parameters, so for a moment I thought you could do this:

mvn dependency:sources -Dclassifier=javadoc -Dtype=jar

but I tried it and it didn't work. Then I checked the source code and found this:

private static final String SOURCE_TYPE = "java-source";
private static final String SOURCE_CLASSIFIER = "sources";

// ...

public void execute()
    throws MojoExecutionException
{
    // parameters are overwritten with constant values
    this.classifier = SOURCE_CLASSIFIER;
    this.type = SOURCE_TYPE;

I have now submitted a Bug concerning this.
