ClassCastException when using extension

[marquiswang]

I have concurrent-build-logger installed in my .mvn/extensions.xml

% cat .mvn/extensions.xml
<extensions>
	<extension>
		<groupId>io.takari.maven</groupId>
		<artifactId>concurrent-build-logger</artifactId>
		<version>0.2.1</version>
	</extension>
</extensions>

but when I run it I get:

% mvn clean install -T1C -Dmaven.logging=
