Hello, I am also very interested in the Java support in CMake. I had a quick look at the source code in cmake and found those files: Source/cmDependsJava.cxx Source/cmDependsJava.h Source/cmDependsJavaLexer.cxx Source/cmDependsJavaLexer.h Source/cmDependsJavaLexer.in.l Source/cmDependsJavaParser.cxx Source/cmDependsJavaParser.y Source/cmDependsJavaParserHelper.cxx Source/cmDependsJavaParserHelper.h So it seems there is a Java parser and lexer written in flex and bison. But the cmDependsJava.cxx file looks empty specially the WriteDependencies method: http://cmake.org/gitweb?p=cmake.git;a=blob;f=Source/cmDependsJava.cxx;h=1d849145cb70ae7bd21cb0fa5c33e289cd0fbc8d;hb=HEAD -- Nicolas Desprès _______________________________________________ Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Follow this link to subscribe/unsubscribe: http://www.cmake.org/mailman/listinfo/cmake
