gwt maven war plugin configuration problem - gwt

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

Adding
<inplace>true</inplace>
in the gwt-maven-plugin configuration tags solved the issue.

Answer 2

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>
