I was trying to install WildFly/JBoss Server in Eclipse IDE Photon Release Candidate 3 (4.8.0RC3) but I'm getting an error. I have attached the screenshot for the same.
Would somebody help me out here in this issue?
I've had the same problem.
In Eclipse -> Help -> Eclipse Marketplace, search for "TM Terminal". Uninstall it, restart Eclipse and try to define a new server again. It will now install Wildfly, at least for me it worked.
