How to config where Syntastic is going to generate the .class files?

Question

I am writing some code to my phd project and I am using VIM as my code editor. As I am coding in Java, I chose Syntastic to check and compile my code. So far so good.

My issue comes when I try to create a directory with all my .classes. I want to do this, because then I intend to create a .jar using this directory using a simple make file. So, this is my scenario:

source code:

C:\Users\LABIMD05\workspace\backhoe-nomvn2\src (all .java)

class files:

C:\Users\LABIMD05\workspace\backhoe-nomvn2\bin\classes (where I want to put all the .classes)

In this way, let's say I am coding br.ufrn.Project. When I use :SyntasticCheck, I want the br.ufrn.Project .class file to be generate at:

C:\Users\LABIMD05\workspace\backhoe-nomvn2\bin\classes\br\ufrn\Project.class

and not at:

C:\Users\LABIMD05\workspace\backhoe-nomvn2\src\br\ufrn\Project.class (the same of the .java)

Here goes the options that I am using at my _vimrc file

let g:syntastic_java_javac_classpath = 'C:\Users\LABIMD05\workspace\szz_lib\*;C:\Users\LABIMD05\workspace\backhoe-nomvn2\bin\classes'
let g:syntastic_java_javac_delete_output = 0
let g:syntastic_always_populate_loc_list = 1
let g:syntastic_mode_map = { 'mode': 'passive',
            \ 'passive_filetypes': ['java']}

THE PROBLEM: Everytime I compile br.ufrn.Project file, the .class file goes to the same directory of the .java file

I thought it would be because Syntastic would create the .class file in the current working directory. Then I used:

cd C:\Users\LABIMD05\workspace\backhoe-nomvn2\bin\classes

To see if Syntastic would create the .class in the desired place. But I had no success.

Would you guys have some clue where can I configure it? I just want to separate the .class files from .java files and then use a make file to create a jar with the binaries only. Simple thing.

Thank you for any help you can provide.

Just to clarify: My environment is: Windows 7, Vim 7.4 – Daniel Alencar Nov 07 '14 at 18:58 — Daniel Alencar, Nov 07 '14 at 18:58

You can't configure Syntastic to compile the java files to a different location. However, you can make a command that uses SyntasticCheck and compiles the java files to a different directory.

Using the javac -d dir File.java command you can tell the java compiler where to generate .class files.

Using this you can make a vim command, I called it Javac but you can choose what to call it. It will call Syntastic check and generate the .class files to the other file.

function! Javac()
    execute "w"
    execute "SyntasticCheck"
    execute "!javac -d C:\Users\LABIMD05\workspace\backhoe-nomvn2\bin\classes %"
endfunction

command! Javac :call Javac()

If the SyntasticCheck part is not necessary you can remove that.

Just put this in your .vimrc and then you can use :Javac to execute it. Alternatively you could also put it in ~/.vim/ftplugin/java.vim if you want it to only be active when editing the java filetype.

Thank you so much @Zach. It solved my problem! However, I have another question: after executing the :Javac command, a cmd line window pops up expecting me to hit any button to close. Do you know what can I do to avoid this it? For example, run the Javac command without any additional window expecting me to hit enter or something? – Daniel Alencar Nov 11 '14 at 17:00
Nevermind @Zach, I figured it out. I used the following command instead: execute "**!start** javac -d C:\Users\LABIMD05\workspace\backhoe-nomvn2\bin\classes %" – Daniel Alencar Nov 11 '14 at 17:06
I'm glad I was able to help! – Zach Nov 11 '14 at 19:49
