Resolving Version Conflicts & Dependency Constraints

Diagnose and fix dependency version clashes using the dependency report, resolution strategies, constraints, and forced versions.

The Conflict Problem

Two libraries you depend on may each pull in a different version of the same transitive dependency. Gradle must pick one — and the wrong choice causes runtime errors. Managing this is a core skill.

Default: Newest Wins

By default Gradle resolves a conflict by choosing the highest requested version of a dependency across the graph. Usually safe, but not always.
