By the way I can always inject me the container
```
@Requirement
PlexusContainer container;
```
and then lookup the object by its (string) class name
Object eventSpy;
```
try {
eventSpy = container.lookup("org.apache.maven.eventspy.EventSpy",
"profiler");
System.out.println("EventSpy is " + eventSpy);
} catch (ComponentLookupException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
```
and then use reflection to call the `EventSpy#onEvent`, but this really
makes the code quite ugly and only because I can't load the interface itself...
> Export the package org.apache.maven.eventspy

> Key: MNG-7479
> URL: https://issues.apache.org/jira/browse/MNG-7479
> Project: Maven
> Issue Type: Improvement
> Components: Core
> Affects Versions: 3.8.5
> Reporter: Christoph Läubrich
> Priority: Major
>
> I'm currently try to fetch a specific EventSpy to inject an event there
> (maven-profiler).
> Sadly in my maven plugin when I try to get it injected:
> @Requirement(role = EventSpy.class, hint = "profiler", optional = true)
> EventSpy eventSpy;
> This results in ClassNotFoundException: org.apache.maven.eventspy.EventSpy
> I noticed that the maven-core do not export the 'org.apache.maven.eventspy'
> package and that is the cause of this, I'd like to suggest to export the
> package as there seem no other standard way to interact/access event spys
> otherwise.
