Does gnatbench (Eclipse Ada plugin from Ada Core Technologies) work at all?

[ramon_garcia <ramon.garcia.f@gmail.com>]

I have tried gnatbench from libre.adacore.com. It can't load at all in
Eclipse. Looking at the software, it looks like the versions of the
plugins are broken. Bellow is what I found. Can anyone confirm that
the public version downloaded from libre.adacore.com works? I reported
the problem to Adacore, but unfortunately I received a rather rude
denial, without any reasoning of the evindence. I find rather
suprising that there is no community of users, or at least googling
for gnatbench finds nothing.

There is a mixture of version numbers 2.4.0.20091211 and 2.4.0. For
instance, the feature com.adacore.gnatbench_2.4.0.20091211.jar , if we
extract the file feature.xml we find that it includes the plugin:

  <plugin
        id="com.adacore.gnatbench.core"
        download-size="0"
        install-size="0"
        version="2.4.0.20091211"/>

But the plugin itself, com.adacore.gnatbench.core, if we look at the
META-INF/MANIFEST.MF, we find that its version is

Bundle-Version: 2.4.0

This was only an example. The versions referenced in this feature are:

com.adacore.gnatbench.core  2.4.0.20091211
com.adacore.gnatbench.doc.user 2.4.0.20091211
com.adacore.gnatbench.library 2.4.0.20091211
com.adacore.gnatbench.library.win32.x86 0.0.0
com.adacore.gnatbench.library.linux.x86 0.0.0
com.adacore.gnatbench.library.linux.x86_64 0.0.0
com.adacore.gnatbench.library.solaris.sparc 0.0.0
com.adacore.gnatbench.ui 2.4.0.20091211
com.adacore.gnatbench.doc.user.standard 2.4.0.20091211
com.adacore.gnatbench.startup 0.0.0

All these plugins are present with version 2.4.0, rather that these
versions 0.0.0 or 2.4.0.20091211.
