Maven build with Place Annotations

[vinnie]

Hi - I'm attempting to convert my GWT app to build with maven.  The first issue I've his is that the compiler does not seem to like the "@WithTokenizers" I have in my PlaceHistoryMapper - at least that's what I think is failing and if I comment those out the application will compile.  Do I need to put some extra configuration in my pom to get this to work?  It compiles fine in eclipse or if I attempt the maven build after eclipse has already compiled the GWT source.

Here's the exception I get:

[ERROR] -> [Help 1]

Maven defaults to Java 1.4 source and target. You have to tell it to use Java 5 or Java 6.

See http://maven.apache.org/plugins/maven-compiler-plugin/examples/set-compiler-source-and-target.html

See also http://maven.apache.org/plugins/maven-compiler-plugin/compile-mojo.html#source

So you can have:

<properties>

<maven.compiler.source>1.6</maven.compiler.source>

<maven.compiler.target>1.6</maven.compiler.target>

</properties>

Thanks, but I already have that set to 1.6.
