can not start java container with command in dockerfile

I have an image that is built using this dockerfile.

# vi Dockerfile
FROM openjdk:8
COPY . /usr/src/myapp
WORKDIR /usr/src/myapp

I can login to container in interactive mode and type this command that works as expected.

 java -jar /usr/src/myapp/dist/some.jar

But if I add this line to Dockerfile, I get an error:

CMD ["/usr/src/myapp/dist/some.jar", "java"] 

docker: Error response from daemon: oci runtime error: container_linux.go:247: starting container process caused "exec: \" -jar /usr/src/myapp/dist/some.jar\": stat  -jar /usr/src/myapp/dist/some.jar: no such file or directory".

How do I add the java command to dockerfile?

Why don't you use the same command as you would type in?

CMD ["java", "-jar", "/usr/src/myapp/dist/some.jar"]

You are using thus wrongly. It should be 

CMD ["java", "-jar", "/usr/src/myapp/dist/some.jar"]

or

CMD java -jar /usr/src/myapp/dist/some.jar
