Project version defined as ${revision} cannot be resolved via maven.config

[ashakirin]

Since maven 3.5.0 it is possible to use ${revision} variable as project version.
One way to resolve this ${revision} is specify it in maven.config file:
maven.config:
-Drevision=2.28.0-SNAPSHOT

This way is not supported by SBM and following exception is thrown by run recipe:
