failed to install CDT package from downloaded zip [message #1770575]

I've downloaded cdt-9.3.1.zip. I've installed Oxygen Eclipse Java EE IDE for Webdevelopers. I have a Mars.2-CDT running (do not remember how I installed it) What now to get CDT 9.3.1 up and running?
(tried to enter the cdt-9.3.1.zip in installation dialog - without success)
(On this computer I am not allowed to install from Market Place or from a URL on the internet)
CDT to be installed on Win7.

What wonders me: the .zip-file does not hold content.jar or artifacts.jar in its top-most directory but in a directory called "repository". Is that .zip-file suited to be used by Eclipse Help/Install New Software ... ?
When I try to I get
Could not find jar:file:/C:/Users/.../cdt-9.3.1.zip!/ leaded by a white cross in a read circle.

Appreciate any help.

I also tried just to copy the content of plugin and feature directory from cdt-9.3.1.zip to the same directories of Eclipse Oxygen (eclipse-jee-oxygen-R-win32-x86_64). Starting Eclipse led to problems with the features. See the attached log file.

Hi Rolf,

Thanks for finding this problem and letting us know. It looks like the zip files have an extra level in them. We'll correct it for the 9.3.2 release (I don't know if we can fix the already released zip).

To use the zip, unzip it and then point at the repository directory that was in the zip file.

PS you can download a fully bundled C/C++ for Eclipse environment from https://www.eclipse.org/downloads/packages/eclipse-ide-cc-developers/oxygenr (choose download links on the right).

Thank you Jonah for providing the link. That worked strait away. Keeping Java and c++ IDE apart - at least for the project browser - seems also a good idea to me.

Hmm - saying that - I could have seperated the IDE environment by workspaces.

(I did a backup of plugin and features of jee installation, hence I was able to undo my trials to fit cdt into jee)

Hi Rolf,

If you are having trouble installing Java and C/C++ in the same installation because you are behind a firewall, one thing you can do is download the two independent full Eclipse installs, one for JEE one for C++ and then combine them.

Steps:
1) Unzip both downloads
2) Start one of them (doesn't matter which, but it will become the one that contains everything)
3) From the File menu -> Import
4) Choose Install -> From Existing Location
5) Select the other install for "From[..]", select what you want to import and continue the wizard until done.

Just for completeness, if you still prefer to reference the original file to install CDT, you can tack on the "repository/" directory to the end of the jar specification and it will still get you there.

i.e. "jar:file:/C:/Users/.../cdt-9.3.1.zip!/repository/"

Hope this helps.

Hi, I was trying to do similar stuff (installing Eclipse+Java+C++ behind a firewall) and the steps Jonah explained worked well. Can I ask how to do the same thing from the command line? So that I can automate the process.

I just tried the following command to see if I can use the installed eclipse as a repository. But this just failed.

eclipse -nosplash -application org.eclipse.equinox.p2.director -repository 'file:[path-to-another-the-other-eclipse]' -list 'Q:everything.select(x | x.properties ~= filter("(org.eclipse.equinox.p2.type.group=true)"))'
