How to generate symbolmap in gwt mvp4g project?

Question

I am using Mvp4g on the gwt client side. I want to generate symbolMap that is used by RemoteLogging Servlet but when I try to generate symbol map using mvn clean install and specifying -extra folder_name property in gwt-maven-plugin configuration, I don't see the symbolMap files. It is not a plain gwt app but its gwt with mvp4g. I don't know whether its mvp4g that is causing the problem.

Answer 1

mvp4g generates Java code on the client side. This happens before the compiler translates the code to JavaScript. Check your settings. May be this post helps. How to generate symbol map in gwt using maven?

Update:

I use this maven configuration:

<gwt.output>myPathToTheProjectDirectory/output</gwt.output>
<gwt.gen>genSources</gwt.gen>
<gwt.extra>extra</gwt.extra>

And this for the maven-gwt-plugin:

  <plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>gwt-maven-plugin</artifactId>
    <version>2.6.1</version>
    <executions>
      <execution>
        <phase>compile</phase>
        <id>bla</id>
        <goals>
          <goal>compile</goal>
        </goals>
        <configuration>
          <draftCompile>false</draftCompile>
          <disableClassMetadata>true</disableClassMetadata>
          <compileReport>true</compileReport>
          <warSourceDirectory>${gwt.war}</warSourceDirectory>
          <webappDirectory>${gwt.output}</webappDirectory>
          <gen>${gwt.output}/${gwt.gen}</gen>
          <extra>${gwt.output}/${gwt.extra}</extra>
          <fragmentCount>8</fragmentCount>
          <extraJvmArgs>-Xms1G -Xmx1G -Xss1024k -XX:MaxPermSize=1024m -Dgwt.persistentunitcache=false</extraJvmArgs>
          <localWorkers>7</localWorkers>
        </configuration>
      </execution>
    </executions>
  </plugin>

In case I execute maven:compile, the symbolmaps are listed inside the folder myPathToTheProjectDirectory/output/extra/symbolmaps.

Answer 2

Try add this: <set-property name="compiler.useSourceMaps" value="true" />

It solves the problem for me.
