I had encounter that few days back.
And what I did is the location of the parent folder contains the pom.xml
into the relativePath just like
<parent>
<groupId>nl.topicus.onderwijs</groupId>
<artifactId>onderwijs-project-parent</artifactId>
<version>1.3</version>
<relativePath><location of your parent folder></relativePath>
</parent>
