UnsupportedVersion after using Jandex Maven Plugin 1.2.0

[Flurb]

For our Quarkus microservice, we upgraded the Jandex Maven Plugin from 1.1.1 to 1.2.0.
During the build, it gives an UnsupportedVersion

Build step io.quarkus.deployment.index.ApplicationArchiveBuildStep#build threw an exception: org.jboss.jandex.UnsupportedVersion: Version: 10

Do we need to upgrade something else in order to use 1.2.0 instead of 1.1.1?

[Ladicek]

Jandex Maven plugin 1.2.0 uses Jandex 2.4.0.Final, which produces newer index format. Quarkus 2.2 uses Jandex 2.3.1.Final, which can't read the new index format. The recommendation would be to not update to Jandex Maven plugin 1.2.0 with Quarkus 2.2 or earlier.

Jandex unfortunately didn't have a written compatibility promise before, I added one here: smallrye/jandex#136 Also unfortunately, the Jandex version and Jandex Maven plugin version are detached -- that should be addressed in Jandex 3.0, where they will both be released together.
