I’m trying to deploy a Java Spring backend application on Render.com, but I’m encountering an issue during the deployment process. Whenever I attempt to deploy, I receive the following error message: “Exited with status 1 while building your code.”

Here’s the Dockerfile I’m using for the deployment:

FROM maven:3.8.3-openjdk-17 AS build
COPY . .
RUN mvn clean package -DskipTests

FROM openjdk:17.0.1-jdk-slim
COPY --from=build /target/demo-0.0.1-SNAPSHOT.jar demo.jar
EXPOSE 8080
ENTRYPOINT ["java", "-jar", "demo.jar"]

I’ve ensured that the Maven build completes successfully on my local machine, and the generated JAR file (demo-0.0.1-SNAPSHOT.jar) exists in the /target directory.

Could anyone help me identify the cause of this issue? I’m relatively new to Docker and deployment processes, so any guidance would be greatly appreciated.
