[jbosstools-issues] cannot find ManagementRequestHandlerFactory

Dear all, I'm trying to run JBossTools in Eclispe Kepler with Wildfly 8.0 server. Adding a server went well, but when I try to start the server from inside eclipse, jbosstools complains : An internal error occurred during: "Starting WildFly 8.0 Runtime 1 Server". org/jboss/as/protocol/mgmt/ManagementRequestHandlerFactory From Eclipse logfile, it seems a jar is missing : !ENTRY org.eclipse.core.jobs 4 2 2013-12-17 17:34:45.511 !MESSAGE An internal error occurred during: "Starting WildFly 8.0 Runtime 1 Server". !STACK 0 java.lang.NoClassDefFoundError: org/jboss/as/protocol/mgmt/ManagementRequestHandlerFactory at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClass(ClassLoader.java:800) at org.eclipse.osgi.internal.baseadaptor.DefaultClassLoader.defineClass(DefaultClassLoader.java:188) .... Can someone help ? Best regards, Mathieu
