Following up on this. I removed all the [] deps from my plugin but
still seem to get the same issue of the class missing.
I definitely see the class in my maven 3.9-staged/lib directory, and
have even updated the dependency version in my plugin to match.
The code in question that's failing is the creation of the Aether
repository system - it's possible this has changed:
```
private static RepositorySystem newRepositorySystem() {
DefaultServiceLocator locator =
MavenRepositorySystemUtils.newServiceLocator();
locator.addService(RepositoryConnectorFactory.class,
BasicRepositoryConnectorFactory.class);
locator.addService(TransporterFactory.class,
FileTransporterFactory.class);
locator.addService(TransporterFactory.class,
HttpTransporterFactory.class);
return locator.getService(RepositorySystem.class);
}
```
and trace was:

Mark,
Can you provide more information about this error?
I understand if this plugin is internal (not OSS), but can you provide
me
the POM of it, or at least the dependencies snippet related to Maven
and
resolver?
"A required class is missing" is strange, especially as
BasicRepositoryConnectorFactory is provided by Maven itself?
Thanks
Tamas
