[MavenResolver] Is there a way to fetch versions from the parent POM?

[bmajsak]

Hi guys,

I have several modules in my project so I defined most of the dependencies which are used across in the parent pom under <dependencyManagement> section. in addition I externalized versions to properties. Pretty standard approach I guess. When I try however to fetch some in the submodule using Maven Resolver I need to explicitly specify version, otherwise it will complain that they are not specified. Does it mean it only look into used pom instead of going up in the hierarchy?

I'm using ShrinkWrap Maven Resolver 2.1.1.

Thanks for your help in advance!

Hi Bartosz,

it should definitely go up the chain. If you see it in mvn help:effective-pom, Resolver should see it as well. You can also try to debug what resolver actually see by grabbing MavenWorkingSession here:

https://github.com/shrinkwrap/resolver#debugging-and-logging

It should work with 2.1.1, there were some fixes w.r.t. classifiers and types in 2.2.0 stream. If that does not work with 2.2.0-beta-1, it's most likely a bug.

Hi Karel,

Sadly, it does not work for me with both 2.1.1 and 2.2.0-beta-1.

I'm getting :

org.jboss.shrinkwrap.resolver.api.ResolutionException: Unable to get version for dependency specified by org.assert:assertj-core:compile, it was not provided in neither <dependencyManagement> nor <dependencies> sections.

And in the effective pom I see:

    <dependency>

      <groupId>org.assertj</groupId>

      <artifactId>assertj-core</artifactId>

      <version>1.7.0</version>

      <scope>test</scope>

    </dependency>

I thought that would be implicit. Should I specify scope too?

I will try to isolate this problem and share it through GitHub.

Is that assertj-core directly in <dependency> or <dependencyManagement> of parent? Or is it transitive dependency? The closest test case in integration test for the former is here - which seems pretty much like your test case:
