I have a Dependency in child pom like this.
sample-groupID
This will solve your problem:
4.0.0
myEAR
myEAR
0.0.1-SNAPSHOT
ear
maven-ear-plugin
2.10
EarContent
false
6
lib
no-version
myWAR
myWAR
0.0.1-SNAPSHOT
war
your final EAR will be myEAR-0.0.1.SNAPSHOT.EAR that contains myWAR.war (without version number) if you want to remove version number from EAR also than add myEar
