java - Why does the m2e plugin build to a WEB-INF/classes in the target folder for a maven jar project? -

since packaging jar (i.e. maven jar project), don't know why m2e insists on setting eclipse project's source folder's output write target/web-inf/classes. tried changing point build/classes, maven -> update project changes back. why? missing project level setting?

update: added pom.xml

the reason happening because had "outputdirectory" tag in <build> section of parent pom.

<!-- hot reload of web application --> <outputdirectory>${project.build.directory}/${project.build.finalname}/web-inf/classes </outputdirectory> 

as removed that, maven update removed "web-inf" .classpath output directories.
