Trying to generate Helm charts using FMP and getting the following error:

This problem is certainly related to a regression issue that we have discovered too recently as fmp doesn't work anymore or very well with a multi maven modules structure.

It can be resolved using fmp version 3.5.30

Bingo, that worked!

Is fabric8io/fabric8-maven-plugin#1184 the related issue?

[cmoulliard]

related issue

Certainly yes

Closing as Helm charts can be generated as expected. Will stick with the version 3.5.30.
