Component used: navigation-safe-args-gradle-plugin
Version used: 1.0.0-alpha06

After updating the safe-args plugin from alpha05 to alpha06, my build fails with the following stacktrace:

org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':app:generateSafeArgsDebug'

Reverting to alpha05 makes the build complete.

I think this is related to the commit addressing this issue: https://issuetracker.google.com/79871405

My navigation graph has this structure:

<navigation>
<fragment>
<action />
<argument />
</fragment>
<include app:graph="@navigation/nav_graph_two" />
...
<action />
</navigation>

That is, there are global actions, fragment destinations with arguments, fragment destinations with actions and an included nested graph (in a separate xml). Every single destination has a valid name and every root <navigation> has an id (everything works with version alpha05 of the plugin). I might guess this is related with global actions, which expect the parent destination to have a name that is not resolved with the alpha06 update. In fact, commenting out all the global actions makes the generateSafeArgsDebug task pass. My graphs have ids in the form "@+id/nav_graph_one".
