[CMake] compiling java

[Rafael Pereira]

I have found some problem while trying to compile java code using cmake.

The code below exposes the problem:

I have the following directory structure:

myhome
 |
 |_ testeCMake
     |
     |_ teste
     |   |
     |   |_ main.java
     |_ CMakeLists.txt


inside teste directory has a main.java with simple code:


public class Main {

   public static void main(String[] args){

   }

}

and CMakeLists.txt:

PROJECT(teste Java)

ADD_LIBRARY(teste teste/Main.java)



When i run inside myhome/testeCMake/teste:

cmake . ; make 

cmake works smoothly... everything's fine.

But if i wanna run cmake inside testeCMake with a CMakeLists.txt point
to 
a CMakeLists.txt inside teste directory, with this new config:

foo
 |
 |_ testeCMake
     |
     |_ teste
     |   |
     |   |_ main.java
     |   |_ CMakeLists.txt
     |_ CMakeLists.txt


foo/testeCMake/CMakeLists.txt:

ADD_SUBDIRECTORY(teste)

and foo/testeCMake/teste/CMakeLists.txt:


PROJECT(teste Java)

ADD_LIBRARY(teste teste/Main.java)


whem i run cmake . and make, i receive the following error:

[foo at localhost testeCMake]$ cmake .
-- Configuring done
-- Generating done
-- Build files have been written to: /home/foo/testeCMake

[foo at localhost testeCMake]$ make
Scanning dependencies of target teste
[100%] Building Java object teste/CMakeFiles/teste.dir/Main.class
javac: directory not found: CMakeFiles/teste.dir
Usage: javac <options> <source files>
use -help for a list of possible options
make[2]: *** [teste/CMakeFiles/teste.dir/Main.class] Error 2
make[1]: *** [teste/CMakeFiles/teste.dir/all] Error 2
make: *** [all] Error 2


It seems that cmake doesn't enter inside the teste directory to execute
javac
and jar, and doesn't find the temporaly(CMakeFiles/teste.dir) directory
that
is inside /home/foo/testeCMake/teste 

The CMake docs doesn't speak anything about it, or i didn't.
Anybody already got this error ? Any ideas or sugestions?

Thanks in advance, Rafael.
