All those messages are expected, except the "Destroying process ..." at the end. I assume that you get that when you kill the Java processes. How long did you wait before killing them? I would suggest that you try again and give it time to complete. GWT compiling is extremelly Also you can reduce the number of permutations generated by the GWT compiler and that will reduce the time it takes to compile. For example, if you are going to use Firefox only as the client you can apply the following patch to reduce the number of permutations to just one:

--- a/frontend/webadmin/modules/webadmin/src/main/java/org/ovirt/engine/ui/webadmin/WebAdmin.gwt.xml +++ b/frontend/webadmin/modules/webadmin/src/main/java/org/ovirt/engine/ui/webadmin/WebAdmin.gwt.xml @@ -19,6 +19,9 @@ <set-property name="gwt.logging.logLevel" value="INFO" /> <set-property name="gwt.logging.popupHandler" value="DISABLED" /> +<!-- Reduce the number of permutations to compile, just for tests: --> +<set-property name="user.agent" value="gecko1_8"/> + <!-- Inherit oVirt UiCommon Web modules and GWT deRPC module --> <inherits name="org.ovirt.engine.ui.GwtExtension" /> <inherits name="org.ovirt.engine.ui.UICommonWeb" /> Then compile with "-Pgwt-admin" only. That will generate the GUI but only for Firefox. In my environment (Intel Core i5 8GB) this reduces the GWT compilation to 4 minutes: [INFO] WebAdmin ... SUCCESS [4:22.581s]

SUCCESS [4:22.581s] With the patch the build was successfull. I then went ahead and freed up some memory by stopping some applications and with that even the fill build tops out at about 90% memory usage so it seems that 8gb is enough after all but only barely. With the patch memory usage topped out at 40% so this would definitely make a difference for people with smaller build systems. The deployment works as well but when I start jboss I get the attached errors. Also the build instructions talk about "<server>:<port>" to access the deployed services. I presume <server> is localhost but what port do I use to access the services?

Can you check if the file quartz-1.8.3.jar is in the folder: JBOSS_HOME/common/lib ?

It doesn't come with jboss, but it is copied there when deploying the oVirt engine (maven "dep" profile: "-Pdep"). Did you build the engine with this profile as well?
