Compile a package using JavaCompiler

Using a java program, I need to compile a package which has a group of .java files, post compilation i need to move .class files to a separate folder.

Instead of using ProcessBuilder class to execute the Java compilation from co开发者_Python百科mmand line, I decided to use JavaCompiler. I am new to JavaCompiler and I succeeded in my first attempt of compiling one .java file at a time. But I don't know how to set classpath (-classpath), destination folder (-d) and the list of .java files for package level compilation.

Can anyone brief me how to set the above said options?

As suggested by Harry Joy, you may use ANT. What he probably meant is not using it from the command-line respectively with a build.xml file, but using it directly from your java program. This way you will have access to the 'fileset/exclude/include...' functionality that you have in ant and save a lot of coding.

Example, pseudo code (not tested and probably not even compiling, just as hint):

Project p = new Project();
p.init();
p.addBuildListener( new SimpleBuildListener() );
p.setBaseDir( new File( "." ).getAbsoluteFile() );

Javac task = (Javac) p.createTask( "javac" );
task.srcdir( srcDirPath );

// Filsets can be built this way
FileSet set = new FileSet();
set.setDir( srcDirPath );
set.setIncludes( "**/*.java" );

task.addFileset( set );
