• Quarkus-cli:
  Works this test on 2.7.6.Final? https://github.com/quarkus-qe/quarkus-test-suite/blob/main/quarkus-cli/src/test/java/io/quarkus/ts/quarkus/cli/QuarkusCliExtensionsIT.java#L99

If does, could you remove 2.7.5.Final Disable annotation

• Life application module:
  Please also update this reference

QuarkusCliExtensionsIT does not work at all with 2.7 stream of registry.quarkus.io: Unable to list extensions: Failed to locate stream 2.7 in platform(s). However should be working with registry.quarkus.redhat.com CLI registry.

• Life application module:
  Please also update this reference
  https://github.com/quarkus-qe/quarkus-test-suite/blob/main/lifecycle-application/pom.xml#L42

That was already updated, please see changed files.

I added registry.quarkus.redhat.com as stream 2.7 does not work with registry.quarkus.io (2.7 has been removed from there)
