I have the following POM structure:
./foobar-common/pom.xml ./abc-window/pom.xml ./abc-datasource/pom.xml
Both abc-window pom.xml is as follows:
The parent in abc-window is listed as:
../foobar-common/pom.xml hu.abc.ringcore foobar-common 1.0
The parent in abc-datasource is listed as:
../foobar-common/pom.xml hu.ratesoft.ringcore foobar-common 1.0
So, they do not have the same groupId.
