Docker-compose - Non-resolvable parent POM: Could not find artifact - spring-boot

Question

I have three pom.xml files, where one is the parent and the two others are the children. The parent is located in a folder named calculatorws and the two children are located separately in two folders(inside the folder calculatorws): calculatorws-calculator and calculatorws-rest and each one of them contains a pom.xml file.
The parent pom.xml file is:
<modelVersion>4.0.0</modelVersion>
<groupId>com.company</groupId>
<artifactId>calculatorws</artifactId>
<version>0.0.1</version>
<packaging>pom</packaging>
<modules>
<module>calculatorws-calculator</module>
<module>calculatorws-rest</module>
</modules>
The pom.xml file of calculatorws-rest is:
<modelVersion>4.0.0</modelVersion>
<parent>
<groupId>com.company</groupId>
<artifactId>calculatorws</artifactId>
<version>0.0.1</version>
<relativePath>../pom.xml</relativePath>
</parent>
<artifactId>calculatorws-rest</artifactId>
<dependencyManagement>
<dependencies>
<dependency>
<!-- Import dependency management from Spring Boot -->
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-dependencies</artifactId>
<version>2.4.0.RELEASE</version>

</dependency>
</dependencies>
</dependencyManagement>
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<java.version>1.8</java.version>
</properties>
The pom.xml file of calculatorws-calculator is:
<modelVersion>4.0.0</modelVersion>
<parent>
<groupId>com.company</groupId>
<artifactId>calculatorws</artifactId>
<version>0.0.1</version>
<relativePath>../pom.xml</relativePath>
</parent>
<artifactId>calculatorws-calculator</artifactId>

</dependencies>
</dependencyManagement>
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

</properties>
I have three Dockerfiles respectively for the parent and the children.
The Dockerfile of the parent is:
FROM maven:3-jdk-8-alpine
COPY pom.xml /application/
WORKDIR /application/
COPY . /application/
RUN mvn clean package
The Dockerfile for calculatorws-rest is:
FROM maven:3-jdk-8-alpine as builder
COPY pom.xml /calculatorws-rest/
WORKDIR /calculatorws-rest/
COPY . /calculatorws-rest/
FROM openjdk:8-jre-alpine
COPY --from=builder /calculatorws-rest/target/calculatorws-rest-0.0.1.jar /rest.jar
EXPOSE 8080
CMD ["java", "-jar", "/rest.jar"]
The Dockerfile for calculatorws-calculator is:
FROM maven:3-jdk-8-alpine as builder
COPY pom.xml /calculatorws-calculator/
WORKDIR /calculatorws-calculator/
COPY . /calculatorws-calculator/
FROM openjdk:8-jre-alpine
COPY --from=builder /calculatorws-calculator/target/calculatorws-calculator-0.0.1.jar /calculator.jar
EXPOSE 8080
CMD ["java", "-jar", "/calculator.jar"]
I run the project using the docker-compose file as shown below:
version: '3.9'
services:
rabbitmq:
image: rabbitmq:3.7.3-alpine
container_name: rabbit
ports:
- 5672:5672
application:
build: .
calculatorws-rest:
build: ./calculatorws-rest
calculatorws-calculator:
build: ./calculatorws-calculator
I fixed the error with the non resolvable parent POM by deleting the RUN mvn clean package from the Dockerfile of calculatorws-rest, but now I get this error:
No goals have been specified for this build. You must specify a valid lifecycle phase or a goal in the format <plugin-prefix>:<goal> or <plugin-group-id>:<plugin-artifact-id>[:<plugin-version>]:<goal>. Available lifecycle phases are: validate, initialize, generate-sources, process-sources, generate-resources, process-resources, compile, process-classes, generate-test-sources, process-test-sources, generate-test-resources, process-test-resources, test-compile, process-test-classes, test, prepare-package, package, pre-integration-test, integration-test, post-integration-test, verify, install, deploy, pre-clean, clean, post-clean, pre-site, site, post-site, site-deploy. -> [Help 1]
I think I have a problem with my structure and I am not getting it.
