License scanner plugin

Scans packages for license information and finds license issues

Bytesafe analyzes packages for license information and displays identified licenses for your registries.

The License Scanner plugin adds on top of that, and scans all packages in a registry and flags potential license issues. License issues include unlicensed packages, identification of custom licenses and unknown license information.

Packages in a registry will be scanned for license issues when:

  • The plugin is enabled (all package versions).
  • A new package version is added.

When a license issue is found by the scanner, a LICENSE badge will be added to the package:
