I did a fork of Ladislav's fork to start looking into what would be required to move quarkus to the CDI 3.0.0 apis using the jakarta package name. The initial effort just gets the quarkus/independent-projects/arc subtree to build and pass its tests. It includes some hacks to alias the following jakarata ee8 classes: javax.annotation.Priority javax.enterprise.inject.Alternative javax.enterprise.inject.Stereotype The reason for this is that the io.quarkus.arc.test.stereotypes.StereotypeAlternativeTest test makes use of a io.quarkus.test.Mock stereotype that comes from the quarkus-test-common module, and I did not want to go overboard with a complete replacement of ee8 to start. This does bring up the question of how to handle aliasing in general. Right now the aliases require duplication of the DotNames being checked. Instead of code like: if (DotNames.PRIORITY.equals(annotation.name())|| DotNames.PRIORITY_JAVAX.equals(annotation.name())) { alternativePriority = annotation.value().asInt(); } One could assign an alias to the DotName: public static final DotName PRIORITY = create(Priority.class, "javax.annotation.Priority"); And have the DotName.equals deal with names that have assigned aliases? My fork: https://github.com/starksm64/quarkus-fork.git The PR just to show the diffs: https://github.com/Ladicek/quarkus-fork/pull/6 Note you have to build/run using the staging profile as many of the jakarta ee 9 apis only exist in the jakarta nexus staging repo. *Scotts-iMacPro:arc starksm$ mvn -Pstaging clean verify* *...* *[**INFO**] * *------------------------------------------------------------------------* *[**INFO**] **Reactor Summary for ArC - Parent pom 999-SNAPSHOT:* *[**INFO**] * *[**INFO**] ArC - Parent pom ................................... **SUCCESS** [ 1.308 s]* *[**INFO**] CDI Lite Extensions - API .......................... **SUCCESS** [ 2.606 s]* *[**INFO**] ArC - Runtime ...................................... **SUCCESS** [ 1.670 s]* *[**INFO**] ArC - Processor .................................... **SUCCESS** [ 3.441 s]* *[**INFO**] ArC - Tests ........................................ **SUCCESS** [ 7.037 s]* *[**INFO**] * *------------------------------------------------------------------------* *[**INFO**] **BUILD SUCCESS* *[**INFO**] * *------------------------------------------------------------------------* *[**INFO**] Total time: 16.202 s* *[**INFO**] Finished at: 2020-09-12T13:29:13-05:00* *[**INFO**] * *------------------------------------------------------------------------*
