koji build --scratch <target>
'git://pkgs.fedoraproject.org/<pkgname>?#<hash>'

You just need to substitute Koji target you want to build for, component
(source package) name and git commit hash that you want to build.  For
example:

koji build --scratch f19-candidate
'git://pkgs.fedoraproject.org/javapackages-tools?#4a755d42fa884cacdb373ac05c8b3b9e62751994'

Unreferenced builds are garbage collected, which means build logs will
eventually be removed.
