cs-resolve

Maven and Ivy dependency resolver

TLDR

Resolve dependencies for an artifact

$ cs resolve [org.typelevel::cats-core:2.9.0]

Show dependency tree

$ cs resolve -t [org.apache.spark::spark-sql:3.4.0]

Resolve with exclusions

$ cs resolve [app:version] --exclude [org.slf4j:*]

Resolve from custom repository

$ cs resolve -r [https://repo.example.com/maven] [org.example::app:1.0]

Check for conflicts

$ cs resolve --conflicts [app:version]

Output as JSON

$ cs resolve --json [app:version]

SYNOPSIS

cs resolve [options] coordinates...

cs resolve performs Maven/Ivy dependency resolution, showing all transitive dependencies for given artifacts. It's useful for understanding dependency trees, finding version conflicts, and debugging classpath issues.
The command resolves but doesn't download artifacts, making it fast for exploring dependencies. Tree view shows the dependency hierarchy, while flat view lists all resolved artifacts with their versions.
Conflict detection helps identify situations where different versions of the same library are requested. The reverse dependency feature helps understand why a particular library is included.

PARAMETERS

COORDINATES

Maven coordinates to resolve (can specify multiple).

-t, --tree

Display dependency tree instead of flat list.

-r URL, --repository URL

Add a custom Maven repository.

--exclude PATTERN

Exclude artifacts matching pattern (groupId:artifactId).

--conflicts

Show version conflicts in dependencies.

--json

Output resolution result as JSON.

--reverse

Show reverse dependencies (what depends on what).

--what-depends-on COORDS

Show what depends on specific artifact.

-q, --quiet

Suppress progress output.

CAVEATS

Resolution accuracy depends on POM/ivy.xml completeness. Some artifacts have optional dependencies that may be missed. Cross-version artifacts (Scala) require appropriate notation (::). Network required for repository metadata.

HISTORY

cs resolve is part of Coursier's dependency management capabilities. Resolution is the core operation that powers both launching applications and fetching artifacts, extracted as a standalone command for analysis and debugging.
