Description

I have maven multi module project with two war child projects:
parent pom.xml
— mainWebapp
— overlayWebapp

mainWebapp has dependency of type war on overlayWebapp
overlayWebapp has only static resources (css, js..)

mvn package (run from parent project) works correctly, mainWebapp.war contains overlaid resources from overlayWebapp

mvn tomcat7:run (run from root parent project) fails with exception:

[INFO] create webapp with contextPath: /mainWebapp
[ERROR] fail to extract war file C:\projekty\FIS\source\overlayWebapp\target\classes, reason:The source file C:\projekty\FIS\source\overlayWebapp\target\classes doesn't exist.
org.codehaus.plexus.archiver.ArchiverException: The source file C:\projekty\FIS\source\overlayWebapp\target\classes doesn't exist.

when I create some classpath resource in overlayWebapp to create overlayWebapp\target\classes directory, there is an different exception:
