**Problem**
When a Gradle-based Grails project is opened, the Grails toolbar actions
(navigation shortcuts between domain classes, controllers, services, views and
tests) stay disabled. They only become active after manually triggering a
Gradle re-sync (e.g. by touching build.gradle and reimporting), which has to be
done every time the project is opened.
**Root cause**
GrailsStartupActivity queues the Grails application detection
(GrailsApplicationManager.queueUpdate()) as soon as the project opens. For
Gradle projects, however, detection relies on external system project data
(GrailsModuleData attached during Gradle sync), which is loaded asynchronously
after project open. At the moment the startup activity runs, that data is not
available yet, so no Grails application is detected — and since nothing
re-triggers detection afterwards, the plugin stays inactive until the next
manual Gradle sync repopulates the data.
**Solution**
In GrailsStartupActivity, re-queue the detection once the external system
data becomes available, using ExternalProjectsManager.runWhenInitialized():
```
ExternalProjectsManager.getInstance(project).runWhenInitialized(() -> {
GrailsApplicationManager.getInstance(project).queueUpdate();
TraitInjectorService.queueUpdate(project);
});
```
If the external system is already initialized, the callback runs
immediately, so the behavior for non-Gradle projects and warm starts is
unchanged. With this change, Grails applications are detected right after
project open and the toolbar actions are enabled without any manual re-sync.
**Testing**
Verified with ./gradlew runIde on IntelliJ IDEA Ultimate 2026.2: opening a
Gradle-based Grails project now enables the toolbar actions immediately after
startup, without forcing a Gradle re-sync.
