Today I encountered a XML validation problem in Eclipse (Luna 4.4.1) that didn’t want to vanish. The IDE spat out a warning relating to some cached DTD data. Especially the hint at
org.eclipse.wst.internet.cache attracted my attention.
So – easy thing, I thought. Cleared the project and recompiled. To no avail. OK, clear all projects and recompile. The warning grinned at me again. Did a clean launch of eclipse. Didn’t help either. You know these happy moments…
So what is the solution? Easy, if you got to know it: Go to
Window -> Preferences -> General -> Network Connections -> Cache. Find the related URL and remove it. Click
Apply and enjoy.
