Can't build Guava using Maven "mvn package"

I have just read about Guava and checked out its source code but don't know how to build it to use. I built jar file using "mvn package" but it generates errors of Guava GWT.

You might need to run "mvn install" first, as Charles Fry explained here:

We have a funny setup where you have to build stuff using 'mvn install' before the other obvious stuff works.

You could also depend on the most recent release using a Maven dependency, if you don't care about TRUNK:

is guava-libraries available in maven repo?
