Github action workflow error for the Dockerfile - docker

Question

I have following Dockerfile:
FROM openjdk:17
RUN mkdir -p /ctk
RUN mkdir -p /ctk/config/tnt/v2/
WORKDIR /ctk
COPY suitexmls/ /ctk/suitexmls/
COPY config/tnt/v2/EventSubscription.json /ctk/config/tnt/v2/
COPY .mvn/ .mvn
COPY mvnw pom.xml ./
RUN chmod +x ./mvnw
RUN ./mvnw dependency:go-offline
COPY src ./src
RUN ./mvnw clean package spring-boot:repackage
CMD ["./mvnw", "spring-boot:run"]
This docker build and excution works fine locally.
But it fails in github action workflow. It gives following error:-
#5 [ 2/11] RUN mkdir -p /ctk
#5 DONE 0.3s
#6 [ 3/11] RUN mkdir -p /ctk/config/tnt/v2/

How to fix this error? I have to add more text to post this quesion.
Updated quesion:
docker-publish.yml code:-

Now Docker build is fine with suggested fix. But push is fails. Error:-

I setup dockerhub secret correclty. Still I can't access why? I have to add more text to post my updated question. It doesn't allow me to post it. I setup dockerhub secret correclty. Still I can't access why?

For your dockerfile add RUN chmod +x ./mvnw after copy mvnw to image as follows. This command give you the execution permission.
FROM openjdk:17
RUN mkdir -p /ctk
RUN mkdir -p /ctk/config/tnt/v2/
WORKDIR /ctk
COPY suitexmls/ /ctk/suitexmls/
COPY config/tnt/v2/EventSubscription.json /ctk/config/tnt/v2/
COPY .mvn/ .mvn
COPY mvnw pom.xml ./
RUN chmod +x ./mvnw
RUN ./mvnw dependency:go-offline
COPY src ./src
RUN ./mvnw clean package spring-boot:repackage
CMD ["./mvnw", "spring-boot:run"]
The docker image tag you are using cause the error. Because to push to the docker hub the tag must contain your name as follows.
tags: <your_user_name>/app:latest
