INET 4.0 installation error OMNET++ 5.4.1 Linux Mint 19 XFCE

When I try to install INET 4.0 on fresh Linux Mint 19 installation with OMNET++ v5.4.1 there is an error message like this:

enter image description here

Here is error text titled "Problem Occured"

Cannot download archive from https://github.com/inet-framework/inet/releases/download/v4.0.0/inet-4.0.0-src.tgz java.lang.RuntimeException: Unexpected error: java.security.InvalidAlgorithmParameterException: the trustAnchors parameter must be non-empty

When I try to reach the download address from command line with

wget https://github.com/inet-framework/inet/releases/download/v4.0.0/inet-4.0.0-src.tgz

mentioned at error screen I can download the INET 4.0 .tgz file.

Also I checked if I could reach internet by pinging.

How can I find what causes this? Any answers are welcome!

Solution

  • Some Eclipse internal error. No quick fix unless you want to get worked up in the Eclipse OMNET++ IDE internals.

    Easiest solution: Go to the INET website or the INET Github repository and download the archive of the latest INET 4.0 release.

    Then just import the INET project ("Import --> Existing Project --> select Archive File") and voila, you got the INET project in your OMNeT++ installation.
