gwt maven war plugin configuration problem

Question

I am developing a gwt application in maven. In this I am using maven war plugin. Everything works fine. When I give mvn install command it builds abc.war file in target folder. But it is not copying compiled javascript files ("module1" and "module2" directories present in target) to war directory. I want to get newly compiled javascript files in war directory. How to achieve this?

Answer 1

While I am unfamiliar with gwt based application using maven, maven war plugin allows adding of external web resources. You could add something similar to the below in the section of maven-war-plugin.

      <webResources>
        <resource>
          <directory>${project.build.directory}</directory>              
          <targetPath>war</targetPath>
          <includes>
            <include>module1/**</include>
            <include>module2/**</include>
          </includes>
        </resource>
      </webResources>

Answer 2

Adding

 <inplace>true</inplace>  

in the gwt-maven-plugin configuration tags solved the issue.
