Eclipse – difference maven build in same pom file.

i have a parent pom file that include 3 module…

and there is difference when i run "mvn install" from command line on the "parent pom" to eclipse m2 plugin (run– maven install).

i can see it when i run from command line it's not and after that try to run "clean" on my tomcat server it show me this error:

(this file he throw "File not found" they really not there…)

but if i go to my parent pom run–>"maven install" it's run just fine with no error when i try to clean..

what could be the reason?

i try to see if "my maven" that run in command line is different maven from eclipse but i didn't find which maven run in eclipse…

thanks in advance..

sorry for my English…
