Failed to resolve the Quarkus application model for project

Error message

Failed to resolve the Quarkus application model for project ${coords}

What it means

This MojoExecutionException wraps an AppModelResolverException raised while resolving the Quarkus application model for the current project's POM coordinates in QuarkusProjectStateMojoBase.resolveApplicationModel. BootstrapAppModelResolver fetches the project POM and its dependency graph to build the app model; any Maven artifact resolution failure surfaces here. The original exception is preserved as the cause.

Solutions

1. Read the caused-by AppModelResolverException to identify the unresolvable artifact and fix its declaration
2. Run mvn install -DskipTests on the multi-module build so sibling module POMs exist in the local repo
3. Delete the corrupt artifact directory under ~/.m2/repository and re-run to re-download
4. Verify repository credentials/mirrors in settings.xml for private artifacts

Example fix

// before
mvn quarkus:update  (fails: cannot resolve com.example:parent:1.0)
// after
mvn install -DskipTests -f parent-pom/ && mvn quarkus:update

// Pre-resolve the project POM to confirm it is available:
// mvn dependency:resolve -f pom.xml   (run before quarkus:update/info)

try {
    ApplicationModel model = resolver.resolveModel(coords);
} catch (AppModelResolverException e) {
    // log the unresolvable artifact from the cause chain, run mvn install -DskipTests, retry
}

When it happens

Trigger: Calling resolveApplicationModel when the project POM or its dependencies cannot be resolved from local/remote repositories — missing parent POM, unresolvable snapshot, corrupted local repo cache, or unmet dependency versions.

Common situations: Never-run multi-module build where sibling modules aren't installed; corrupted ~/.m2 repository entries; missing private repository credentials; broken parent BOM version in pom.xml.
