To me it seems like error during GWT compilation, i.e. invocation of gwt-maven-plugin's compile goal that performs GWT compilation.

Failed to execute goal org.codehaus.mojo:gwt-maven-plugin:2.5.1:compile (gwtcompile) on project webadmin: Command [[
...
]] failed with status 1

Can we re-run this build with mvn -X flag to see debug-level Maven logs?

Looking at [1] I have some questions/comments:

* I don't see any "-Dgwt.userAgent=..." override, shouldn't Makefile ensure this is set properly?
  Without this, oVirt GUI is compiled for *all* browsers supported by GWT SDK, which increases compilation time & memory usage.
  Note that oVirt GUI should be compiled *only* for following browsers [2]: ie8,ie9,gecko1_8,safari,opera

* maybe set "-Dgwt.compiler.localWorkers=..." to #_of_logical_CPUs available on that host
  Higher value means faster compilation but can increase memory usage (until we move away from JVM-based worker processes)

[2] frontend/webadmin/modules/pom.xml -> gwt.userAgent property -> lists all supported browsers
