classpath.vim

This plugin sets the 'path' for JVM languages to match the class path of your current Java project. This lets commands like :find and gf work as designed. I originally wrote it for Clojure, but I see no reason why it wouldn't be handy for other languages as well.

Currently, Maven and Leiningen are supported, with a fallback to $CLASSPATH if neither applies. Open an issue if you have ideas for supporting another project management system.

Included is a :Java command, which executes java (or $JAVA_CMD) with the current buffer's 'path' as the class path.

Installation

If you don't have a preferred installation method, I recommend installing pathogen.vim, and then simply copy and paste:

cd ~/.vim/bundle
git clone git://github.com/tpope/vim-classpath.git

Once help tags have been generated, you can view the manual with :help classpath.

FAQ

Why does it take so long for Vim to startup?

The short answer is because the JVM is slow.

The first time you load a Clojure file from any given project, classpath.vim sets about trying to determine your class path, leveraging either lein classpath or mvn dependency:build-classpath. This takes a couple of seconds or so in the best case scenario, and potentially much longer if it decides to hit the network.

Because the class path is oh-so-expensive to retrieve, classpath.vim caches it in ~/.cache/vim/classpath. The cache is expired when the timestamp on project.clj or pom.xml changes.
