Facing error while building docker.

Questions / Help
1

My docker build which was working totally fine before is now failing at below step of docker.

RUN mvn package -DskipTests

Getting error –

failed to fetch an image or build from source: error building: failed to solve: executor failed running [/bin/sh -c mvn package -DskipTests]: exit code: 1

Here is my whole docker file.

Using a base image with JDK 11 and Gradle

FROM maven:3.8.6-openjdk-11 AS *build

set as working directory*

WORKDIR /app

# Copy files from your project to the working directory
COPY . /app

# Run Gradle to build the project
RUN mvn package -DskipTests

# Create a new image based on OpenJDK 11
FROM openjdk:11-jre-slim-buster

# Expose the port that the application will use
EXPOSE 8080

# Copy the JAR file built from the previous step
COPY --from=build /app/target/kaim-backend-0.0.1-SNAPSHOT.jar /app/kaim-backend-0.0.1-SNAPSHOT.jar

# Set the entry point to run the application
ENTRYPOINT [“java”, “-Dspring.profiles.active=prod”, “-jar”, “/app/kaim-backend-0.0.1-SNAPSHOT.jar”]

Earlier it was working fine just out of nowhere issue started coming andnow deployments are stuck.

Am using flyctl for deploying my docker build and running application.

A general approach to solving problems like these.

Create a file named Dockerfile.min with the following contents:

FROM maven:3.8.6-openjdk-11
WORKDIR /app
COPY . /app

Now run:

fly console --dockerfile Dockerfile.min -C /bin/bash

Once that gets you to a command prompt, run your command:

mvn package -DskipTests

The output will come to your screen. Given the information you posted, all we know is that this command failed. Hopefully the output tells you why.
