java - Stop eclipse from resetting root context when Maven->Update Project / MANIFEST.MF file not found -

i building application using eclipse, maven, tomcat, , spring framework.

every time need "clean ..." or "clean work directory" tomcat, end having use "maven->update project" tool in order stop manifest.mf file not found error. after that, have update context root "/" instead of project name.

is there anyway can stop eclipse resetting context root? or there anyway stop manifest.mf not found error?

maybe there's better way manage root context?

after successful maven build, refresh root project beofre deploying app tomcat server
