I'm designing a portable Minecraft launcher with multiple version launching support and need to set the classpath and appdata variable. I know that you can set the classpath using

System.setProperty(

             "java.class.path",

             "./");

however I'm not sure will work to set the path to local.

My second issue is finding the java code equivalent of batch

APPDATA=%CD%\minecraft

. I have looked into exec() but don't know if this will work on MAC/LINUX.

I'm developing on Console, not Swing
