Werid problem about 'implements' in mxml file.

Question

Hi, all:
There are more than 50 modules in my project, We build it with flexmojos 4.0-alpha-5. Most of the time, I goes well, but built failed occasionally, error message as fllows:
Error: Cannot resolve attribute 'implements' for component type spark.components.Group.
All errors come from mxml file that implements some interface, for example:
<Group xmlns:fx="http://ns.adobe.com/mxml/2009"
               xmlns:s="library://ns.adobe.com/flex/spark"
               xmlns:mx="library://ns.adobe.com/flex/mx"
              implements="some.interfaces.name">
</Group>
some elements in my pom.xml:
<configurationReport>false
<useNetwork>true
<verifyDigests>true
<linkReportAttch>false
<sizeReportAttch>false
<AllowSourcePathOverlap>true
<staticLinkRuntimeShareLibraries>false
<quick>false
<optimize>true
Flex compiler version:4.5.1.21328
Anybody got some error like that? or give me some advice for it, thanks for advance.

Thanks, Craberoid.
We tried 4.2, but error occoured as before.
More than 50 modules use 20g+ memory to build, that is flexmojos's another problem, so we changed maven to Ant... it work well.
