Pub CLI Usage

This page describes the CLI commands to retrieve, publish, and upload packages after creating and configuring a Pub repository on Nexus.

Retrieve Pub Content

After configuring Pub to use the Nexus repository, use Dart or Flutter commands from your workspace.

dart pub get
flutter pub get
dart pub upgrade
flutter pub upgrade
dart pub downgrade

Where,

• dart pub get - downloads required packages through the Nexus Pub repository
• flutter pub get - fetches packages referenced in the Flutter project's pubspec.yaml
• dart pub upgrade - refreshes package versions when updates are available
• flutter pub upgrade - updates packages to the latest compatible versions
• dart pub downgrade - resolves packages to the oldest compatible versions

Example:

dart pub get
flutter pub get

Publish Pub Packages

You can publish your packages by using the dart pub publish command, the Components REST API, or the Nexus Repository UI. Sonatype recommends using the following dart pub publish command.

dart pub publish --server https://[NEXUS_URL]/repository/<REPO_NAME>

Where,

• [NEXUS_URL] - The URL of your Nexus instance, for example example.sonatype.com
• <REPO_NAME> - The name of the target hosted repository in Nexus, for example pub-hosted

Example:

dart pub publish --server https://example.nexus.com/repository/pub-hosted

You can also publish using the Components REST API:

curl \
  -X POST \
  "https://[NEXUS_URL]/service/rest/v1/components?repository=<REPO_NAME>" \
  -u "USERNAME:PASSWORD" \
  -F "pub.asset=@{package-name}-{version}.tar.gz" \
  -F "pub.name={package-name}" \
  -F "pub.version={version}"

Where,

• [NEXUS_URL] - The URL of your Nexus instance
• <REPO_NAME> - The name of the target hosted repository in Nexus
• {package-name} - Package name as defined in pubspec.yaml
• {version} - Semantic version, for example 1.0.0

Example:

curl \
  -X POST \
  "https://example.nexus.com/service/rest/v1/components?repository=pub-hosted" \
  -u "publisher:[PASSWORD]" \
  -F "pub.asset=@example_package-1.0.0.tar.gz" \
  -F "pub.name=example_package" \
  -F "pub.version=1.0.0"

You can also upload Pub packages from the Nexus Repository UI.
