I suspect that lzc is using the java tmp dir for the compilation manage
cache
In Main.lzx it says
String tmpdirstr = System.getProperty("java.io.tmpdir");
String cachetmpdirstr = tmpdirstr + File.separator + "lzccache";
(new File(cachetmpdirstr)).mkdirs();
String mediaCacheDir = cachetmpdirstr + File.separator + "cmcache";
String scriptCacheDir = cachetmpdirstr + File.separator + "scache";
If I want to add something to the ant "clean" target which deletes the
tmp/lzccache dir,
anyone know how I do that? I Need to get the value of java.io.tmpdir from
ant.
Does anyone know how to get the value of a system property like that within
ant?
