[Solved]-GWT-Maven-plugin: Link GWT compiled files into a defined directory-eclipse

from the documentation at https://gwt-maven-plugin.github.io/gwt-maven-plugin/compile-mojo.html,

webappdirectory file - location on filesystem where gwt will write output files (-out option to gwtcompiler). default value is: ${project.build.directory}/${project.build.finalname}. user property is: gwt.war.

you appear to be using -war instead, which i believe is the much older version of -out, but adding <webappdirectory>${project.build.directory}/thisfolder</webappdirectory> to your configuration should achieve the desired result.
