I was attempting to do some programming from a machine at work and I am unable to get Vim to recognize folds in my Java program. I've set the foldmethod to "syntax", but I get: "No Fold Found" when I try to collapse method bodies. I changed the filetype to "cpp" to test foldmethod=syntax and it worked!
I attempted to compare 'java.vim' and 'cpp.vim' to see if I could discern the problem, but I could not make out an issue with 'java.vim'.
My 'java.vim' has the following header:
" Vim syntax file
" Language: Java
" Maintainer: Claudio Fleiner <claudio@fleiner.com>
" URL: http://www.fleiner.com/vim/syntax/java.vim
" Last Change: 2007 Dec 21
Does anyone have any ideas?
Which Vim version?
The default Vim 7.3.000 install ships syntax/java.vim with a version of 2010 March 23; the latest runtime files (from Mercurial repo) have 2012 Oct 05; both can do Java folding. I strongly recommend you to upgrade.
If you cannot do this, put the following into ~/.vim/after/syntax/java.vim:
if v:version < 703
" The default Java syntax file lacks the 'fold' option.
syn region javaFold start="{" end="}" transparent fold
