No the binaries are tarfile or zip (jar wouldn't work because of the permissions).
Thanks for your answer, I'll do it my way.
(couldn't zip files be available as Maven artifacts? I think so, see org.jboss.as:jboss-as-dist for example)
I don't think so maven care about the OS/Platform and a single zip for all platform would be too big.
You can use classifiers to avoid that.
Anyway I wasn't asking for this as an improvement, but to know if it was already available.
