Hi all, I am having some trouble building the engine with `mvn clean install -Pgwt-admin,gwt-user -DskipTests=true -X`, the output I eventually get indicates a failure in building WebAdmin. I am doing this in a clean F16 environment with a fresh clone of the repository. The javac version is javac 1.6.0_22. http://pastebin.com/VZvUpmTK Any suggestions on how to get past this and successfully building the WebAdmin stuff? Thanks, Steve

Hi, It could be an error either in java or the libraries it is building on, very environment dependent. Did this javac command leave an crash report behind?

also can you please try running this without the 'clean' phase, i want to see if it is related to some kind of timeout mvn install -Pgwt-admin,gwt-user -DskipTests=true -X

Based on Doron's suggestion earlier in the thread I decided to throw more memory at the problem. I then received a java.lang.OutOfMemoryError: PermGen space error, setting MAVEN_OPTS="-XX:MaxPermSize=128m" seems to have fixed this and I have now built sucessfully. Thankyou for your suggestions! I have added the perm gen space error tip to http://www.ovirt.org/wiki/Building_oVirt_engine#Build, more generally we probably need to consider some hints/recommendations around what kind of computing power (particularly memory) is required to successfully compile the project. -Steve
