How to configure the Maven multi module build to get a CodeCoverage report in Azure with jacoco

I have a Maven Multi-Module Build. This works fine in the Azure Build Pipeline. Now I try to add CodeCoverage Report. For that I added this to my azure-pipelines.yml

- task: PublishCodeCoverageResults@2
  displayName: 'Publish code coverage report'
  inputs:
    codeCoverageTool: 'JaCoCo'
    summaryFileLocation: '**/target/site/jacoco/jacoco.xml'
    reportDirectory: '**/target/site/jacoco'
    failIfCoverageEmpty: false
    pathToSources: '$(System.DefaultWorkingDirectory)/**/src/main/java/'

then in the two Maven module I added this

  <plugin>
            <groupId>org.jacoco</groupId>
            <artifactId>jacoco-maven-plugin</artifactId>
            <executions>
                <execution>
                    <goals>
                        <goal>prepare-agent</goal>
                    </goals>
                </execution>
                <!-- attached to Maven test phase -->
                <execution>
                    <id>report</id>
                    <phase>test</phase>
                    <goals>
                        <goal>report</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>

I get this output in the target

The same I did in another module.

Note my verion for all modules is 1.1.3

The problems is now when the Build runs in Azure Pipeline. I see this:

The Version 1.0-SNAPSHOT does not exist in my project.

Do you have an idea what the problem is?
