eclipse - Install child modules' 3rd party dependencies to local maven repo -

i have big maven project has smaller child modules. imported project using m2e eclipse plugin , got lots of compilation errors in eclipse.

after built whole project using mvn clean install of errors gone(because maven plugin able find dependencies in local repository , reference them there), child modules still show lots of compilation error because child modules' dependencies missing local repo. dependencies getting copied in /lib folder inside target folder of child module.
