It said the two commands I was trying to run (genEclipseRuns and Eclipse) were not found as tasks in "Pokem" the root project (I did not make the project it was already there)
I first downloaded 1.14.4, then I extracted it, then I opened CMD and ran gradlew, then I ran the other two commands he said, and it came up with errors
Regardless, you did not necessarily explain what exactly I should do other than download gradle which I already have gathering virtual dust somewhere in file explorer
