**Affects:** 3.2.0

**Attachments:**
- [tez_assembly.xml](https://issues.apache.org/jira/secure/attachment/13019203/tez_assembly.xml) (_2.81 kB_)

Start with the failing path at ResolutionManagementInfo.java:44 and follow DefaultDependencyResolver, using the supplied tez_assembly.xml and Maven Assembly Plugin 3.2.0 configuration to reproduce the failure. Verify the useTransitiveDependencies=false case and add coverage for it; done means the assembly no longer raises NullPointerException.
