[ https://issues.jboss.org/browse/JBIDE-12365?page=com.atlassian.jira.plugi... ] Alexey Kazakov commented on JBIDE-12365: ---------------------------------------- As I said you don't need to disable KB validation for every project in your worspace. Just disable it Preferences -> JBoss Tools -> Web -> Knowledge Base -> Validator and clean/rebuild your workspace. If you already have some warnings then this won't help (when you disable validation, the old warning are not removed). I have created a new issue for that bug - JBIDE-20913 As workaround you can set "Capabilities are not enabled in Java uitl module" to "Ignore" in Preferences -> JBoss Tools -> Web -> Knowledge Base -> Validator. Then clean/rebuild the workspace. It will remove the validtion warnings. KB is not for JSF2 only. It's more general and used by JSF, Batch and some other tooling too. JBoss Tools maven integration enables KB for Java EE maven projects automatically. You can disable this integration in Preferences -> JBoss Tools -> Maven integration. Seam, CDI, JSF integration it's what you need to disable if you don't want JBoss Tools automatically configure the corresponding maven projects. -- This message was sent by Atlassian JIRA (v6.4.11#64026)
