How to use the command 'cs resolve' (with examples)
The ‘cs resolve’ command is a dependency resolution tool that lists the transitive dependencies of one or more dependencies. It helps manage dependencies in a project by providing information about the dependencies that are required by the specified artifacts.
Use case 1: Resolve lists of transitive dependencies of two dependencies
Code:
cs resolve group_id1:artifact_id1:artifact_version1 group_id2:artifact_id2:artifact_version2
Motivation: This use case is useful when you want to check the transitive dependencies of two specific dependencies. By specifying the group ID, artifact ID, and version of the dependencies, you can get a detailed list of the dependencies required by those artifacts.
Explanation:
cs resolve: The command to resolve the dependencies.group_id1:artifact_id1:artifact_version1: The first dependency to check.group_id2:artifact_id2:artifact_version2: The second dependency to check.
Example output:
com.google.guava:guava:29.0-jre
+-- com.google.guava:failureaccess:1.0.1
+-- com.google.guava:listenablefuture:9999.0-empty-to-avoid-conflict-with-guava
+-- com.google.code.findbugs:jsr305:3.0.2
+-- org.checkerframework:checker-qual:3.8.0
+-- com.google.errorprone:error_prone_annotations:2.5.1
+-- com.google.j2objc:j2objc-annotations:1.3
+-- com.google.protobuf:protobuf-java:3.14.0
+-- com.google.guava:guava-testlib:29.0-jre (test)
+-- org.codehaus.mojo:animal-sniffer-annotations:1.18 (test)
Use case 2: Resolve lists of transitive dependencies of a package by the dependency tree
Code:
cs resolve --tree group_id:artifact_id:artifact_version
Motivation: Sometimes, you may need to visualize the dependency tree of a specific package. This use case allows you to see all the transitive dependencies of a package in a hierarchical structure.
Explanation:
cs resolve: The command to resolve the dependencies.--tree: An option that displays the dependency tree.group_id:artifact_id:artifact_version: The package to check the transitive dependencies.
Example output:
com.google.guava:guava:29.0-jre
+--- com.google.guava:failureaccess:1.0.1
+--- com.google.guava:listenablefuture:9999.0-empty-to-avoid-conflict-with-guava
+--- com.google.code.findbugs:jsr305:3.0.2
+--- org.checkerframework:checker-qual:3.8.0
+--- com.google.errorprone:error_prone_annotations:2.5.1
+--- com.google.j2objc:j2objc-annotations:1.3
+--- com.google.protobuf:protobuf-java:3.14.0
\--- com.google.guava:guava-testlib:29.0-jre (test)
Use case 3: Resolve dependency tree in a reverse order
Code:
cs resolve --reverse-tree group_id:artifact_id:{{artifact_version}}
Motivation: There are cases where you start with a specific dependency and want to understand which other artifacts depend on it. By using the reverse tree option, you can identify dependencies that depend on the specified artifact.
Explanation:
cs resolve: The command to resolve the dependencies.--reverse-tree: An option that displays the dependency tree in reverse order.group_id:artifact_id:artifact_version: The artifact to check the reverse dependencies.
Example output:
com.google.guava:guava:29.0-jre
\--- com.example:my-app:1.0-SNAPSHOT
Use case 4: Print all the libraries that depend on a specific library
Code:
cs resolve {{group_id}}:{{artifact_id}}:{{artifact_version}} --what-depends-on {{searched_group_id}}:{{searched_artifact_id}}
Motivation: When managing dependencies, it is essential to know which libraries depend on a specific library. This use case helps identify all the libraries that depend on the searched library.
Explanation:
cs resolve: The command to resolve the dependencies.group_id:artifact_id:artifact_version: The library to check the dependencies.--what-depends-on: An option that shows the libraries that depend on the specified library.searched_group_id:searched_artifact_id: The library to search for in the dependencies.
Example output:
com.google.guava:guava:29.0-jre
\--- com.example:my-app:1.0-SNAPSHOT
Use case 5: Print all the libraries that depend on a specific library version
Code:
cs resolve {{group_id}}:{{artifact_id}}:{{artifact_version}} --what-depends-on {{searched_group_id}}:{{searched_artifact_id}}{{searched_artifact_version}}
Motivation: In some scenarios, you may want to find all the libraries that depend on a specific version of a library. This use case helps identify libraries that rely on a particular version of the searched library.
Explanation:
cs resolve: The command to resolve the dependencies.group_id:artifact_id:artifact_version: The library to check the dependencies.--what-depends-on: An option that shows the libraries that depend on the specified library.searched_group_id:searched_artifact_id:searched_artifact_version: The library to search for with a specific version.
Example output:
com.google.guava:guava:29.0-jre
\--- com.example:my-app:1.0-SNAPSHOT
Use case 6: Print eventual conflicts between a set of packages
Code:
cs resolve --conflicts group_id1:artifact_id1:artifact_version1 group_id2:artifact_id2:artifact_version2 ...
Motivation: When dealing with multiple dependencies in a project, it is crucial to identify any potential conflicts between packages. This use case allows you to check for any conflicts between a set of packages.
Explanation:
cs resolve: The command to resolve the dependencies.--conflicts: An option that displays any conflicts between packages.group_id1:artifact_id1:artifact_version1 group_id2:artifact_id2:artifact_version2 ...: The set of packages to check for conflicts.
Example output:
Conflict: com.google.guava:guava:29.0-jre
- com.google.http-client:http-client:1.0
- org.apache.httpcomponents:httpclient:4.5.6
Conclusion:
The ‘cs resolve’ command is a powerful tool for managing dependencies in a project. It provides various use cases to help developers understand and analyze their dependencies. By using this command, you can easily resolve transitive dependencies, visualize the dependency tree, identify reverse dependencies, find dependencies of a specific library, check conflicts between packages, and more.
