javacomplete

Java omni-completion for Vim 7.x

Starting point of the projec is:

• https://github.com/VictorDenisov/javacomplete, by Victor Denisov, which in turn is started by
• http://www.vim.org/scripts/script.php?script_id=1785, created by Mr. Fang Cheng.

I do not take credit for any of the work, I have contacted the authors about these modifications.

Modifications

javacomplete.vim is a vim plugin that uses

• a java parser written in plain vim for completion in source code files.
• a java reflection class written in java for completion from jars / .class files

I have made the following changes:

• added javacomplete#GoToDefinition; should open the definition of any varible inside the file, or outside

• changed the Reflection.java mechanism with a new tool, that ** introspects and saves caches with parsed source / introspection data for both source and binary classes

• the vim script parser is kept for the current file.

Dependencies

• Sun JDK
• nailgun client installed

Usage

In ftplugin/java.vim - Add the following to enable javacomplete:

setlocal omnifunc=javacomplete#Complete

You will also need this:

let g:nailgun_port='2113'

GoToDefinition example keybind:

<leader>b :call javacomplete#GoToDefinition()<CR>

Create a vim script file containing the list of classes, jars and source paths in your project:

call javacomplete#AddClassPath('/home/user/.m2/repository/asm/asm/3.1/asm-3.1.jar')
call javacomplete#AddClassPath('/path/to/class/files')
call javacomplete#AddSourcePath('/path/to/source')
...

Source the file, edit something in your project. C-x C-o gets you omni completion, b goes to definition
