copy (file/fileset, to dir, failonerror),
delete (file/dir/fileset, verbose, failonerror),
echo(message, level) - can also write message between open echo tag & closing echo tag,
ear(destfile, appxml),
jar(destfile, basedir, includes),
javac(srcdir, destdir, classpath failonerror),
java(classname, jar),
mkdir(dir),
move(file, todir),
property(name value),
