(cherry picked from commit 20d628fa)

... so no need to complete it.

This reverts commit a859d2e9.
I pushed relevant jars yesterday but doesn't look like they hit central
yet.

session cookie name.

Integrating a newer version of libaries that have the correct license
header in POM and source code.

Looks like there are some rogue versions of POMs out there that doesn't
have the license info like the official ones do.

Still planning to improving the error message from the plugin, too.

A build failure was reported, whose  root cause is that the central (http://repo2.maven.org/maven2/javax/mail/mail/1.4/mail-1.4.pom) and the source of the repository (http://maven.glassfish.org/content/groups/public/javax/mail/mail/1.4/mail-1.4.pom) have different POMs. So if your local repository was pre-populated with JavaMail from central you get this error.

Relaxing a rule a bit.

the UI.

Also, for the core build, require that all the dependency licenses are
available.
