Error when use polyglot with tycho-pomless

[duongdominhchau]

Here is the repo I used: https://github.com/duongdominhchau/tycho-example/tree/error

It is based on the vogella example, I just added polyglot-yaml to extensions.xml and it fails. The output of mvn package is stored in maven-log-0.4.6.txt. I saw it failed injecting, my guess is the difference between polyglot-common version used in tycho-pomless and polyglot-yaml results in two choices for injection. However, when I use polyglot-yaml 0.4.5 (the version used by tycho-pomless), it fails too (maven-log-0.4.5.txt).

I use Maven 3.6.3 with OpenJDK15 on ArchLinux.

Ok, now that we have some CI in place, and a release made. We can take a look at this. Polyglot Maven 0.4.7 will be in Maven Central in 30 minutes, so if this is an issue let us know and we'll try to get this addressed.
