Classpath resource + pomPropsPath + is missing groupId

Error message

Classpath resource + pomPropsPath + is missing groupId

What it means

QuarkusGradleUtils/QuarkusDev loads a quarkus-build-catalog poms.properties resource from the dev-mode classpath to determine the GAV coordinates of the quarkus-bootstrap resolver dependency. If the properties file exists but lacks the groupId key, QuarkusDev.getQuarkusBootstrapResolver throws this GradleException. It indicates a malformed or truncated quarkus maven/gradle plugin properties resource on the classpath, typically from a broken Quarkus installation or corrupted local repository artifact.

Solutions

1. Clear the cached quarkus plugin artifacts: delete io/quarkus entries from ~/.gradle/caches/modules-2 and ~/.m2/repository/io/quarkus, then re-run with --refresh-dependencies.
2. Align the Quarkus Gradle plugin version with the Quarkus platform/BOM version in build.gradle.
3. Verify the poms.properties file on the classpath contains groupId/artifactId/version keys.
4. Re-import/refresh the project in the IDE to rebuild the classpath.

Example fix

// before: mismatched plugin and platform
id 'io.quarkus' version '3.0.0.Final'
implementation enforcedPlatform('io.quarkus.platform:quarkus-bom:3.15.0')
// after
id 'io.quarkus' version '3.15.0'
implementation enforcedPlatform('io.quarkus.platform:quarkus-bom:3.15.0')

// Verify the plugin artifact metadata is intact before running dev mode
Process p = new ProcessBuilder("unzip", "-p",
    "/path/to/quarkus-gradle-plugin.jar", "META-INF/maven/io.quarkus/pom.properties")
    .start();
String props = new String(p.getInputStream().readAllBytes());
if (!props.contains("groupId=")) throw new IllegalStateException("Corrupted Quarkus plugin artifact; clear caches");

try {
  ./gradlew quarkusDev
} catch (GradleException e) {
  if (e.getMessage().contains("is missing groupId")) {
    // purge ~/.gradle/caches/modules-2 and ~/.m2/repository io.quarkus entries, re-run with --refresh-dependencies
  }
}

When it happens

Trigger: Running a dev-mode task (quarkusDev) where the resolved poms.properties classpath resource does not contain a 'groupId' entry; happens inside getQuarkusBootstrapResolver, invoked by getQuarkusGradleBootstrapResolver and getQuarkusMavenBootstrapResolver.

Common situations: Corrupted entries in ~/.m2/repository or Gradle cache for quarkus plugin artifacts; a partially downloaded/overwritten pom.properties; mixing mismatched Quarkus Gradle plugin and Quarkus BOM versions; manually editing or excluding plugin resources.
