[ https://issues.jboss.org/browse/JBIDE-18697?page=com.atlassian.jira.plugi... ] Martin Malina commented on JBIDE-18697: --------------------------------------- I just tried this again and it still works fine for me :( I wish we could reproduce this, then we could do something about it, but we still can't. I have Windows 10 64-bit, Eclipse Neon, WildFly 10 and a simple dynamic web project deployed as exploded war. It still seems to me that the error indicates that eclipse cannot write to that deployment directory for some reason. Have you tried unzipping a new WildFly server in a new directory? Somebody wrote this on the stackoverflow post: {quote} I was getting the same error message, turns out it was because something went wrong in the deployments folder of JBoss, it wasn't even allowing me to delete my project ear folder from deployments. My solution was, unzipped another instance of JBoss and pointed my Eclipse to this JBoss and then it worked fine. {quote} -- This message was sent by Atlassian JIRA (v6.4.11#64026)
