Classpath resource <pomPropsPath> is missing artifactId

Error message

Classpath resource <pomPropsPath> is missing artifactId

What it means

DevMojo reads artifactId from the quarkus-bootstrap-maven-resolver pom.properties and throws this MojoExecutionException when the key is absent. Like the groupId check, it validates that the classpath resource carries complete Maven coordinates for the dev-mode launcher artifact.

Solutions

1. Delete and re-download quarkus-bootstrap-maven-resolver from ~/.m2/repository with -U
2. Align quarkus-maven-plugin version with the Quarkus platform version
3. Inspect the jar's pom.properties and confirm all three coordinate keys are present

unzip -p <resolver.jar> META-INF/maven/io.quarkus/quarkus-bootstrap-maven-resolver/pom.properties | grep artifactId

When it happens

Trigger: The pom.properties resource for quarkus-bootstrap-maven-resolver contains a groupId but no `artifactId` property — a malformed or stripped metadata file in the jar.

Common situations: Repackaged or manually edited jar missing parts of META-INF/maven metadata; corrupted artifact served by a mirror; custom build pipeline rewriting pom.properties.
