Resolve from pom.xml: old version is picked

With a pom.xml including the following dependencies the resulting archive contains spring-aop-4.1.7.RELEASE.jar, although I expect version 4.2.1 to be included. The latter is what maven does on the command line. I have the same issue with spring-beans, spring-context, spring-core, and spring-expression.

File[] libs = Maven.resolver().loadPomFromFile("pom.xml").importRuntimeAndTestDependencies().resolve().withTransitivity().asFile();
webArchive.addAsLibraries(libs);
