Can you try without the protoSourceRoot option since the value for it you specified is the default anyway?

<protocArtifact>io.grpc:protoc-gen-grpc-java:1.64.0:exe:${os.detected.classifier}</protocArtifact>

That should not be a protocArtifact. It is overwriting the previous setting:

<protocArtifact>com.google.protobuf:protoc:3.25.1:exe:${os.detected.classifier}</protocArtifact>

Instead, you want to use protoc-gen-grpc-java as the pluginArtifact. See the example pom.xml:

grpc-java/examples/pom.xml

Lines 102 to 104 in b181e49

	<protocArtifact>com.google.protobuf:protoc:${protoc.version}:exe:${os.detected.classifier}</protocArtifact>
	<pluginId>grpc-java</pluginId>
	<pluginArtifact>io.grpc:protoc-gen-grpc-java:${grpc.version}:exe:${os.detected.classifier}</pluginArtifact>

Seems like this is resolved. If not, comment, and it can be reopened.
