Failed to run dockerfile -> unknown instruction: APT-GET - amazon-web-services

Question

Alright, so I'm trying to create a kind of pipeline to put my application online at Amazon AWS.
I am using the following dockerfile:
FROM maven:3.8.5-openjdk-17 AS MAVEN_BUILD
RUN apt-get update && \
apt-get upgrade -y && |
apt-get install git -y
WORKDIR /repositorio/
RUN git clone https://gitlab.com/booking_hub/grupo_04_bookinghub.git
COPY /repositorio/grupo_04_bookinghub/backend/APIrest/APIrest/pom.xml /build/
COPY /repositorio/grupo_04_bookinghub/backend/APIrest/APIrest/src /build/src/
WORKDIR /build/
RUN mvn clean install "-Dmaven.test.skip=true" && mvn package
FROM openjdk:17-slim
WORKDIR /app
COPY --from=MAVEN_BUILD /build/target/APIrest-*.jar /app/APIrest.jar
ENTRYPOINT ["java","-Dspring.profiles.active=dev", "-jar", "APIrest.jar"]
I'm having the following error:
error

I am stuck in this error and don't know what to do. The official maven image says it runs a Ubuntu based image so APT-GET should've worked.
I tried to change the maven version to 3.8.1 where I found out that this version still used a Ubuntu based where APT-GET work but the same error occurred.
I expect the dockerfile to download a maven image, run a git clone of my project and build it inside the docker image (which will be called by a docker-compose file)

Looks like https://hub.docker.com/_/maven is on oraclelinux which is redhat based.
See https://github.com/carlossg/docker-maven/blob/ac292f26884bf2be9fe69f6e397da3b124c1e35c/openjdk-18/Dockerfile#L1
I think you should try https://oracle-base.com/articles/linux/installing-software-packages#rpm and https://oracle-base.com/articles/linux/installing-software-packages#yum as your package managers.
Good luck!
