Possible bug in the ProjectBuilder (3.5.4) ?

[Cristiano]

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
DefaultProjectBuildingRequest();
request.setLocalRepository(session.getLocalRepository());
        request.setRemoteRepositories(
session.getCurrentProject().getRemoteArtifactRepositories());
        request.setResolveDependencies(pResolveDependencies);
request.setRepositorySession(session.getRepositorySession());
        request.setInactiveProfileIds(
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,
request).getProject();
    }


In order to test it I'm trying to read this [pom]
https://search.maven.org/classic/#artifactdetails%7Cbr.com.c8tech.releng%7Cfpom-deps-felix%7C2.1%7Cpom.

    <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(
                    new
DefaultArtifact("br.com.c8tech.releng:fpom-deps-felix:pom:2.1"),
                    true);

}

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.

Caused by: org.apache.maven.project.ProjectBuildingException: Some

line 337, column 21

could someone tell me if its a missing feature, a bug or maybe am I
missing something ?


thanks a lot,


Cristiano

Ok, I found where the problem was... :-)

Certainly I do not set necessary objects to new instance of
ProjectBuildingRequest  that I was doing.

Once I have reused the instance provided by the MavenSession instance,
the errors gone !

ProjectBuildingRequest request = session.getProjectBuildingRequest();

best regards,

Cristiano
