junit @4.6: error: Source option 1.5 is no longer supported. Use 1.6 or later.

When performing the following installation: sudo port install subversion-javahlbindings +no_bdb +universal I get the following error:

Error: Failed to build junit: command execution failed
Error: See /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_java_junit/junit/main.log for details.

The log says:

The junit port is very old and may just need to be updated. I tried to do that years ago and failed; see #27086. Maybe the situation has improved since then.

This also affects the ports: swi-prolog-* and others for which unit is a dependency.

[ianroberts (Ian Roberts)]

Why does JUnit need to build from source anyway? The "build" process for the apache-ant port seems to simply download the already-compiled binary distribution and install that, could JUnit do something similar?

I've encountered this problem too!

[chrstphrchvz (Christopher Chavez)]

I believe this is fixed by [a25b56bd7d/macports-ports] (junit 4.12_0): the port now uses the prebuilt binary distribution instead of building from the source distribution. Can this ticket be closed?
