I have an existing Eclipse CDT installation (Eclipse IDE for C/C++ Developers). It is version 4.2, Juno. I want to add java support via JDT. To makes things slightly more complex, the machines running Ecilpse are on a private LAN with no internet access.

So far I have not been able to find an update repository for the JDT plugins. Other plugins I have needed, I simply downloaded the zip from their update repository, copied the zip to the offline machines, then added it using "install new software" from archive. Does anyone know where I can download the corresponding zip files for JDT?

As a fall back, I created a mirror of the main 4.2 Juno repository ( using P2 as outlined here. I had assumed JDT would be part of the main project but I was wrong. JDT does not appear in the mirrored site. Does anyone know the correct repository URL to get JDT?

I feel like I am taking crazy pills. I cant figure out how to get JDT offline without downloading an Eclipse package that comes with it bundled. I appreciate any help.

I found the right repository address, or what I thought was the right one. I used Just for the sake of completeness, here are the commands to create a mirror of the repository when run on a Windows platform. All other platforms use eclipse rather than ecipsec.

eclipsec -nosplash -verbose application org.eclipse.equinox.p2.metadata.repository.mirrorApplication
 -destination c:\4_2_mirror

eclipsec -nosplash -verbose -application org.eclipse.equinox.p2.artifact.repository.mirrorApplication
 -destination c:\4_2_mirror

So now I have my repository on DVD and I go to install Eclipse Java Development Tools. The installation begins but errors out with the following message.

An error occurred while collecting items to be installed
session context was:(profile=epp.package.cpp, phase=org.eclipse.equinox.internal.p2.engine.phases.Collect, operand=, action=).

I guess there are some required packages that were not part of the mirror.

Regardless, I think I will simply install a second instance of Eclipse rather than continuing to try to add JDT support to a CDT installation.
