Possible bug in the ProjectBuilder (3.5.4) ?

Cristiano Gavião
Hello, I need some assistance in order to identify whether the issue I'm
facing is a bug or a missing feature.

I'm adding a goal to my plugin that must read a POM project from a
repository and get details about the dependencies declared on it.

In order to build the POM object I've created the method below that are
using Core's org.apache.maven.project.ProjectBuilder:

             public MavenProject loadProject(Artifact artifact,
        MavenSession session,
                     boolean pResolveDependencies) throws
        ProjectBuildingException {
                 ProjectBuildingRequest request = new
        Arrays.asList("when-building-java-using-java8"));  ---> I added
        this in order to try no get one of the errors reported.
                 return projectBuilder.build(artifact,

    In order to test it I'm trying to read this [pom]

    This POM has declared a POM fragment:

>         <dependencyManagement>
>             <dependencies>
>                 <dependency>
>     <groupId>br.com.c8tech.releng</groupId>
>                     <version>2.1</version>
>     <artifactId>fpom-deps-osgi</artifactId>
>                     <scope>import</scope>
>                     <type>pom</type>

    And I'm using this code:


          pom = loadProject(


    The error I'm getting from ProjectBuilder is about not being able to
    get the versions declared in the imported POM ( declared in its
    dependencyManagement) and also not being able to determine the Java
    version of a profile activated by <jdk> property.
