protoc-gen-grpckt: program not found or is not executable

After following the steps in the README.md file I am not able to generate the proto files from the command line

git clone [e-mail]:grpc/grpc-kotlin.git
cd grpc-kotlin/
./gradlew build
vi test.proto // make some test proto file
mkdir testDir
protoc --plugin=protoc-gen-grpc-kotlin=build/artifacts/protoc-gen-grpc-kotlin --grpckt_out=testDir --proto_path=. test.proto

And the result from this is

protoc-gen-grpckt: program not found or is not executable
Please specify a program using absolute path or make sure the program is available in your PATH system variable
--grpckt_out: protoc-gen-grpckt: Plugin failed with status code 1.

protoc version - 3.11.4

@jamesward alternatively you can prepend the shebang on *nix systems:

$ cat <(echo '#!/usr/bin/java -jar') protoc-gen-grpc-kotlin-0.2.1-jdk7.jar > protoc-gen-grpc-kotlin.jar
$ ./protoc-gen-grpc-kotlin.jar

0.1.5 is working as binary but the build jar for 0.2.0 is not working.

Download URL: https://repo1.maven.org/maven2/io/grpc/protoc-gen-grpc-kotlin/0.2.0/protoc-gen-grpc-kotlin-0.2.0-jdk7.jar

Tried chmod +x on the jar file without success.
