Answer 1

You have to run mvn gwt:compile additionally to the usual mvn clean install package, as the GWT-compilation is NOT part of the maven-package-phase. This solves the annoying Javascript-(re)compile-error.

Answer 2

My Dev mode was correctly configured and above solution didn't work. Following did solve the issue though.

Multiple steps:

1. Update Project properties -> deployment Assembly using Deploy GWT maven project with eclipse deploys webapp directory instead of target/project directory
2. mvn clean package
3. mvn gwt:compile
4. In eclipse, click on 'GWT Compile Project' -> Advacned -> Remove '-war src/main/webapp' argument and hit compile.

Output should be like this - Linking into target/project-1.0-SNAPSHOT/ModuleName

... and deployment works fine.
