Starter project does not build with the enforced minimum version of maven

The org-apache-sling-starter  project does not build with maven 3.3.9 which is the current enforcer minimum version.

The bnd-indexer-maven-plugin doesn't appear to work with maven 3.3.9 even with the skip flag set to true.   It reports lots of nasty exceptions and fails the build.

I did some additional testing and it looks like maven version 3.5.0 is the minimum version that seems to work.

Do we need to enforce/change the minimum maven version required to build sling to something newer than 3.3.9?
