The filename or extension is too long
I used the built-in GWT compiler (2.5.0) in Eclipse 4.2.1. After a few hours compilation, I finally got the following error. Any suggestion will be greatly appreciated.

Re: Out of Memory during GWT compile

gwt-lib and gwt-app packagings are for GWT code only (gwt-app will only
package the generated JS/HTML); you shouldn't mix client and server code in
the same Maven module (you can make a shared module, but then I think you
shouldn't bundle your gwt.xml, sources and super-sources within that JAR;
YMMV). Have a look at the e2e integration test for an example, and see
http://blog.ltgt.net/announcing-gwt-maven-archetypes-project/ for the
rationale (well, I think I explained it in this blog post).
Otherwise, well, they'll use all source roots and resources so you can
have as many as you want (e.g. some plugin that generates Java sources and
adds the folder as a source root; or using the build-helper-maven-plugin to
add a folder from src/main as a source root; it doesn't matter where the
source root comes from).
2. I have a huge project ( 1000 database tables). I like to generate
many gwtar files for my internal team in order to reduce gwt compilation
time. How do I do it? Should I use CompileModule from prompt? I like to get
one script how to generate a gwtar file?
I'd call CompileModule using the exec-maven-plugin then. At the
process-classes or prepare-package phases, everything (compiled classes and
their sources, and resources) should be in the
${project.build.outputDirectory} so you shouldn't have to deal with the
classpath and can just use ${project.build.outputDirectory} as the -out
folder for CompileModule.
I'm curious now: did you measure the gains? I've been told Google actually
doesn't use gwtar for their internal libs and given how their build system
works they can't take advantage of the PersistentUnitCache from previous
runs; admittedly they have huge build resources but we also know that speed
matters for them, so if they could save some time in downstream
compilations I'd think they'd use the existing tool (CompileModule) for
that?
