Docker build succeeds in my local but auto build on docker hub linked to my Github account fails. Can you please suggest where am I going wrong?
Dockerfile
FROM openjdk:8-jdk-alpine
RUN addgroup -S spring && adduser -S spring -G spring
USER spring:spring
ARG JAR_FILE=target/*.jar
COPY ${JAR_FILE} app.jar
ENTRYPOINT ["java","-jar","/app.jar"]
My Build configuration on DockerHub
Here’s Build Error
Step 5/6 : COPY ${JAR_FILE} app.jar
COPY failed: no source files were specified
