Github action workflow error for the Dockerfile

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:-

name: Docker

on:
  push:
    branches: [ master ]
    # Publish semver tags as releases.
    tags: [ 'v*.*.*' ]
  pull_request:
    branches: [ master ]

jobs:
  build:

    runs-on: ubuntu-latest
    permissions:

      - name: Cache local Maven repository
        uses: actions/cache@v2

        run:  echo ${{ secrets.DCSA_USER }} && mvn -B package -DskipTests -X
        
      - name: Extract Build tag
        id: buildtag
        run:  echo "TAG=$(mvn org.apache.maven.plugins:maven-help-plugin:3.2.0:evaluate -Dexpression=project.version -q -DforceStdout)">> $GITHUB_ENV

      - name: Login to Docker Hub
        uses: docker/login-action@v2
        with:
          username: ${{ secrets.DOCKERHUB_USERNAME }}
          password: ${{ secrets.DOCKERHUB_PASSWORD }}

      # Build and push Docker image
      - name: Build and push
        uses: docker/build-push-action@v3
        with:
          push: true
          tags: user/app:latest

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
