   Worth noting that this is not specific to Java 24 nor to Gradle snapshots. The issue remains on Java 25 and 26, as well as stable Gradle 9 releases.

   I managed to work around the issue by adding the following Gradle init file with Claude's help (~/.gradle/init.d/ide-import-compat.init.gradle.kts):

   import org.gradle.api.internal.project.ProjectInternal
   
   // Gradle 9.x requires an exclusive project lock to resolve any configuration.
   // When the Gradle Build Server fetches the IDE model via a BuildAction, it resolves
   // all resolvable configurations (annotationProcessor, checkstyle, compileClasspath, …)
   // without holding individual sub-project locks, causing:
   //   "Resolution of the configuration '...' was attempted without an exclusive lock."
   //
   // Fix: pre-resolve ALL resolvable configurations in gradle.projectsEvaluated, which fires
   // after ALL afterEvaluate callbacks complete. We acquire each project's lock explicitly via
   // applyToMutableState so hasMutableState() is true during resolution.
   // DefaultConfiguration.resolveGraphIfRequired() then short-circuits on the cached result
   // before the hasMutableState() check when the GBS model builder runs.
   if (gradle.startParameter.taskNames.isEmpty()) {
       gradle.projectsEvaluated {
           rootProject.allprojects {
               val projectOwner = (this as ProjectInternal).owner
               configurations
                   .filter { it.isCanBeResolved }
                   .forEach { config ->
                       projectOwner.applyToMutableState { _ ->
                           try {
                               config.resolve()
                           } catch (_: Exception) {
                               // Ignore — best-effort pre-resolution; IDE import takes priority.
                           }
                       }
                   }
           }
       }
   }
