Error message

No platforms detected in the project

What it means

GradleUtils.getQuarkusCoreVersion throws GradleException when the project declares no BOM dependencies at all — meaning no Quarkus platform BOM (e.g. io.quarkus.platform:quarkus-bom) was detected via listProjectBoms.

Solutions

1. Add the Quarkus platform BOM: implementation enforcedPlatform("io.quarkus.platform:quarkus-bom:<version>") to the project's dependencies
2. Call getQuarkusCoreVersion on the correct subproject that actually applies Quarkus
3. Check that the BOM is declared in the implementation configuration, not only custom configurations

Example fix

// before
dependencies { implementation "io.quarkus:quarkus-rest" } // no platform
// after
dependencies {
    implementation enforcedPlatform("io.quarkus.platform:quarkus-bom:3.x.y")
    implementation "io.quarkus:quarkus-rest"
}

List<Dependency> boms = GradleUtils.listProjectBoms(project);
if (boms.isEmpty()) { throw new IllegalStateException("Add a Quarkus platform BOM to build.gradle"); }
String v = GradleUtils.getQuarkusCoreVersion(project);

try { v = GradleUtils.getQuarkusCoreVersion(project); } catch (GradleException e) { /* no platform BOM declared */ }

When it happens

Trigger: Calling getQuarkusCoreVersion(project) on a project whose implementation configuration (including enforcedPlatform/platform declarations collected by listProjectBoms) contains no BOM dependencies.

Common situations: build.gradle missing `enforcedPlatform("io.quarkus.platform:quarkus-bom:...")` / `platform(...)`; version catalog or centralized repository declarations invisible to the implementation configuration; calling the util on the root project instead of a subproject.
