Recently I started to work on hadoop and big data processing, but I was frustrated on eclipse and the development environment. We run hadoop on a remote cluster, but develop map-reduce programs on laptop. The development cycle was pretty slow because we need to upload the jar for every release. Another thing is Eclipse is too inefficient for a Vim and Emacs hacker like me. Thankfully I’m not the only one who think this way; Eric Van Dewoestine developed Eclim which can let you work on java programs on headless eclipse and vim/emacs! Here comes the installation steps:
Install Eclipse
I thought it wasn’t that difficult to install the Eclim on remote server, but actually it’s not that trivial to do. The key is to use local eclipse in your home directory instead of using package manager to install eclipse. I tried a whole afternoon, but still couldn’t make Eclim work with Ubuntu pre-packaged eclipse (using apt-get, of course).
To install eclipse, follow the links on it’s official website, and click linux download link to get the actual url. After it starts to download, stop the download process and copy the url. I couldn’t find direct download link on Eclipse website, maybe this shadowed link would help:

Extract the tar-ball somewhere in your home directory. The rest of the steps are as same as Eclim official installation guild.
Other dependencies
Although we want to run Eclim in CLI environment, we still need X11 to run Eclipse daemon. To do so we need to install xvfb
and other build tools.

Install Eclim
The rest of the steps are pretty easy. Note that I put eclipse at home directory; you may need to modify this parameter to your eclipse location.

Starting Eclim
To start Eclim, first start a headless X11 display, then start the Eclim daemon.

By default it will create a workspace
in your home directory, you should put all your java projects there. When creating new projects, use :ProjectCreate
in Vim (do not create yourself by mkdir
, Eclim don’t know what that is). If you want to delete or rename a project, use :ProjectDelete
and :PorjectRename
.
Now you can reach whole eclipse ecosystem directly from vim! Enjoy!
