Maven Compilation for GWT 2.7 SOYC Fails

Question

How do i generate GWT Soyc report in 2.7?

GWT 2.7 maven project created using following archetype command.

mvn archetype:generate -DarchetypeGroupId=org.codehaus.mojo -DarchetypeArtifactId=gwt-maven-plugin -DarchetypeVersion=2.7.0

I am trying to generate soyc report for it. I have tried 2 approaches and both are failing in creating a soyc report. Is this feature abandoned.

Approach 1 - I have tried using configuration parameters in the pom.xml

            <compilerMetrics>true</compilerMetrics>
            <compileReport>true</compileReport>
            <detailedSoyc>true</detailedSoyc>

Approach 2 - I have tried using mvn command line argument

mvn -Dgwt.compiler.soycDetailed=true clean install

However, the build passes without creating soyc with following exception

Answer 1

Try removing the detailed Soyc parameter. I ran into this issue as well; I was generating SOYC no problem, then it started failing, so I tweaked my settings until I got SOYC back. With json soyc enabled and detailed Soyc disabled, I still get plenty of details showing me where my compile size is coming from.

Here's what I'm using at present:

-XjsInteropMode JS -XmethodNameDisplayMode NONE -Xnamespace NONE
-style OBFUSCATED -sourceLevel 1.8 -compileReport -XnocompilerMetrics
-XnocheckCasts -XnoclassMetadata -XclusterFunctions -XinlineLiteralParameters
 -XoptimizeDataflow -noincrementalCompileWarnings -XenableJsonSoyc 
-nooverlappingSourceWarnings -saveSource -soycReport -XnodetailedSoyc 
-optimize 9 -setProperty compiler.stackMode=strip net.wetheinter.webcomponent.GwtcTest

Note to anyone else who stumbles upon this, I set a java exception breakpoint on EmptyStackException and found the empty stack seemed to happen around LongLibBase. This may be a compiler bug, as this is an intrinsic class that is generally treated differently than other classes.
