Compilation of the example DnComponents fails

[lofidewanto]

I could run the example with the devmode, everything works fine. But as soon as I try to compile in "pure" Maven I get following error:

[INFO] --- maven-compiler-plugin:3.8.1:compile (default-compile) @ gwt-boot-sample-ui-dncomponents ---

With devmode I could run the webapp without any problems.

I'm not sure why I get the error... There is this annotation processor in the compiler (see pom.xml):

            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>3.8.1</version>
                <configuration>
                    <source>8</source>
                    <target>8</target>
                    <compilerArgs>
                        <arg>-Aregister=AppTemplates</arg>
                    </compilerArgs>
                    <annotationProcessors>
                        <annotationProcessor>com.dncomponents.TemplateProcessor</annotationProcessor>
                    </annotationProcessors>
                </configuration>
            </plugin>

Got exactly the same error on Travis: https://travis-ci.org/github/gwtboot/gwt-boot-samples

Done with a workaround in Maven compiler plugin:

Done for now

Please revert this: `

org.apache.maven.plugins

            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.8.1</version>
            <configuration>
                <source>8</source>
                <target>8</target>
                <compilerArgs>
                    <arg>-Aregister=AppTemplates</arg>
                </compilerArgs>
                <annotationProcessors>
                    <annotationProcessor>com.dncomponents.TemplateProcessor</annotationProcessor>
                </annotationProcessors>
            </configuration>
        </plugin>`

No need for workaround after annotation processor bug fixed in dncomponents version 2.3.2 .

Thanks
