Error thrown while trying to start nexus "Error: Could not find or load main class com.install4j.runtime.launcher.UnixLauncher"

Need help on this error while trying to start nexus “Error: Could not find or load main class com.install4j.runtime.launcher.UnixLauncher”. The .install4j of nexus somehow before was deleted. In this regard what are the steps to take to fix the issue. Need some guidance.

Is this a new installation or a pre-existing one?

Does the user that you are trying to start the service have ownership of the entire Application/Data directory?

You could try chown -R OWNER{:GROUP} /opt/nexus (or wherever your installation is).

Does this post help: Error: Could not find or load main class com.install4j.runtime.launcher.UnixLauncher ?

It doesn’t help me with my issue unfortunately.

Yes, this is a pre-existing one. And in terms of the ownership, it doesn’t have any problem regarding that part. The main issue was that the “.install4j” was deleted for some reason before and now it won’t run and it throws that error. Do you have any suggestion on how to fix this issue. I would appreciate it.

Is it possible that this was accidentally deleted? Could you try re-downloading the bundle and copying over just the file that you are missing?

I tried re-doing that but I still get the same error though.

The java .install4j is deleted. Need some guidance.

If you’re still experiencing the problem after Laurence’s suggestion of re-downloading Nexus and re-installing it suggests you’ve got some sort of environmental problem.
