Re: Compile multiple modules in one project

Note that you've defined more than one gwt:compile execution into a single maven module. The maven plugin you're using is capable of this, but not really designed for it - please consider splitting into multiple maven modules (1:1 with the gwt modules they seek to compile).

Only one of your <execution>s defines <moduleName>, and the error is letting you know that at least one execution doesn't define a moduleName.

As it happens, you have three executions as your project is configured: DiagonalSlitherlink, DiagonalSlitherlink2, and "default-cli" the default execution. All three are required to have a moduleName to be able to run. 

I believe that dropping the "gwt-app" packaging will opt you out of the default wiring that the plugin assumes, and get rid of default-cli, but you also may have some additional setup to do to make the project work once you've removed all the default wiring.

What are you trying to achieve with this?

So, I put this into my pom.xml:
<build>
<plugins>
<plugin>
<groupId>net.ltgt.gwt.maven</groupId>
<artifactId>gwt-maven-plugin</artifactId>
<version>1.1.0</version>
<extensions>true</extensions>
<executions>
<execution>
<id>DiagonalSlitherlink</id>
<goals>
<goal>compile</goal>
</goals>
<configuration>
<failOnError>true</failOnError>
<logLevel>INFO</logLevel>
</configuration>
</execution>
<execution>
<id>DiagonalSlitherlink2</id>
<goals>
<goal>compile</goal>
</goals>
<configuration>
<failOnError>true</failOnError>
<logLevel>INFO</logLevel>

<moduleName>com._3dmathpuzzles.gwt.DiagonalSlitherlink2</moduleName>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>

But I get this error from Maven:
