A full-featured license tool to check and fix license headers and resolve dependencies' licenses.
You can use License-Eye in GitHub Actions or in your local machine.
First of all, add a .licenserc.yaml in the root of your project, for Apache Software Foundation projects, the following configuration should be enough.
Note: The full configurations can be found in the configuration section.
header: license: spdx-id: Apache-2.0 copyright-owner: Apache Software Foundation paths-ignore: - 'dist' - 'licenses' - '**/*.md' - 'LICENSE' - 'NOTICE' comment: on-failure # If you don't want to check dependencies' license compatibility, remove the following part dependency: files: - pom.xml # If this is a maven project. - Cargo.toml # If this is a rust project. - package.json # If this is a npm project. - go.mod # If this is a Go project. - Gemfile.lock # If this is a Ruby project (Bundler). Ensure Gemfile.lock is committed.
To check license headers in GitHub Actions, add a step in your GitHub workflow.
- name: Check License Header uses: apache/skywalking-eyes/header@main # always prefer to use a revision instead of `main`. # with: # log: debug # optional: set the log level. The default value is `info`. # config: .licenserc.yaml # optional: set the config file. The default value is `.licenserc.yaml`. # token: # optional: the token that license eye uses when it needs to comment on the pull request. Set to empty ("") to disable commenting on pull request. The default value is ${{ github.token }} # mode: # optional: Which mode License-Eye should be run in. Choices are `check` or `fix`. The default value is `check`.
By default the action runs License-Eye in check mode, which will raise an error if any of the processed files are missing license headers. If mode is set to fix, the action will instead apply the license header to any processed file that is missing a license header. The fixed files can then be pushed back to the pull request using another GitHub action. For example:
- name: Fix License Header uses: apache/skywalking-eyes/header@main with: mode: fix - name: Apply Changes uses: EndBug/add-and-commit@v4 env: GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }} with: author_name: License Bot author_email: license_bot@github.com message: 'Automatic application of license header'
Warning: The exit code of fix mode is always 0 and can not be used to block CI status. Consider running the action in check mode if you would like CI to fail when a file is missing a license header.
Note: In 0.3.0 and earlier versions, GitHub Actions
apache/skywalking-eyesonly works for header check/fix, since 0.4.0, we have a dedicate GitHub Actionsapache/skywalking-eyes/headerfor header check/fix and a GitHub Actionsapache/skywalking-eyes/dependencyfor dependency resolve/check. Nowapache/skywalking-eyesis equivalent toapache/skywalking-eyes/headerin order not to break existing usages ofapache/skywalking-eyes.
To check dependencies license in GitHub Actions, add a step in your GitHub workflow.
- name: Check Dependencies' License uses: apache/skywalking-eyes/dependency@main # always prefer to use a revision instead of `main`. # with: # log: debug # optional: set the log level. The default value is `info`. # config: .licenserc.yaml # optional: set the config file. The default value is `.licenserc.yaml`. # mode: # optional: Which mode License-Eye should be run in. Choices are `check` or `resolve`. The default value is `check`. # flags: # optional: Extra flags appended to the command, for example, `--summary=path/to/template.tmpl`
License-Eye can resolve Ruby dependencies and their licenses directly from Gemfile.lock.
Rules applied:
Requirements:
Minimal config snippet:
dependency: files: - Gemfile.lock
GitHub Actions example:
name: Apache SkyWalking Eyes permissions: contents: read on: push: branches: - 'main' - '*-stable' tags: - '!*' # Do not execute on tags pull_request: branches: - '*' # Allow manually triggering the workflow. workflow_dispatch: # Cancels all previous workflow runs for the same branch that have not yet completed. concurrency: # The concurrency group contains the workflow name and the branch name. group: "${{ github.workflow }}-${{ github.ref }}" cancel-in-progress: true jobs: license-check: if: "!contains(github.event.commits[0].message, '[ci skip]') && !contains(github.event.commits[0].message, '[skip ci]')" runs-on: ubuntu-latest steps: - name: Checkout uses: actions/checkout@v5 - name: Check Dependencies' License uses: apache/skywalking-eyes/dependency@main with: config: .licenserc.yaml # Ruby packages declared as dependencies in gemspecs or Gemfiles are # typically consumed as binaries; enable weak-compatibility # so permissive and weak-copyleft combinations are treated as compatible. flags: --weak-compatible
Note: License-Eye may query the RubyGems API to determine licenses when they are not specified in your configuration. Ensure the workflow has network access.
The following flags are available for all commands:
| Flag name | Short name | Description |
|---|---|---|
--verbosity | -v | Set log level (debug, info, warn, error, fatal, panic). Default: info |
--config | -c | Path to the configuration file. Default: .licenserc.yaml |
Examples:
license-eye --verbosity debug --config .licenserc.yaml header check license-eye -v warn -c path/to/.licenserc.yaml dep resolve
For Bash, users can execute the following command,
docker run -it --rm -v $(pwd):/github/workspace apache/skywalking-eyes header check docker run -it --rm -v $(pwd):/github/workspace apache/skywalking-eyes header fix
For PowerShell 7, users can execute the following command,
docker run -it --rm -v ${pwd}:/github/workspace apache/skywalking-eyes header check
docker run -it --rm -v ${pwd}:/github/workspace apache/skywalking-eyes header fix
To check dependencies' licenses in Docker, you'll need the appropriate language runtime and package managers in your environment. The base Docker image only includes the license-eye binary. To check dependencies, you can build a custom Docker image with your required language tools:
FROM apache/skywalking-eyes:latest # Install the tools you need
See the examples directory for more detailed examples and Dockerfiles for different languages.
For users and developers who want to help to test the latest codes on main branch, we publish a Docker image to the GitHub Container Registry for every commit in main branch, tagged with the commit sha. If it‘s the latest commit in main branch, it’s also tagged with latest.
Note: these Docker images are not official Apache releases. For official releases, please refer to the download page for executable binary and the Docker hub for Docker images.
docker run -it --rm -v $(pwd):/github/workspace ghcr.io/apache/skywalking-eyes/license-eye header check docker run -it --rm -v $(pwd):/github/workspace ghcr.io/apache/skywalking-eyes/license-eye header fix
git clone https://github.com/apache/skywalking-eyes cd skywalking-eyes make build
Notes: The make build command will generate a bin directory in the current project directory. Choose the appropriate binary file according to your operating system.
If you have the Go SDK installed, you can also use the go install command to install the latest code.
go install github.com/apache/skywalking-eyes/cmd/license-eye@latest
If you don’t have it installed, you can install it by running the following command in terminal:
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
Then install license-eye using the following command:
brew install license-eye
license-eye -c test/testdata/.licenserc_for_test_check.yaml header check

This command can be used to perform automatic license compatibility check, when there is incompatible licenses found, the command will exit with status code 1 and fail the command.
license-eye -c test/testdata/.licenserc_for_test_check.yaml dep check
It supports three flags, in addition to the global ones:
| Flag name | Short name | Description |
|---|---|---|
--weak-compatible | -w | Treat weak-compatible licenses as compatible during checks. Use with caution and manually confirm the usage conditions for such licenses are met. |
--fsf-free | -f | Only consider licenses marked as FSF Free/Libre when determining compatibility. Non‑FSF‑free licenses are treated as incompatible. |
--osi-approved | -o | Only consider OSI‑approved licenses when determining compatibility. Non‑OSI‑approved licenses are treated as incompatible. |
Example using weak-compatible mode:
license-eye -c test/testdata/.licenserc_for_test_check.yaml dep check -w

header section is configurations for source codes license header. If you have multiple modules or packages in your project that have differing licenses, this section may contain a list of licenses:header: - path: "/path/to/module/a" license: spdx-id: Apache-2.0 - path: "/path/to/module/b" license: spdx-id: MPL-2.0
content or pattern. This will be used as the content when fix command needs to insert a license header.[owner] in the SPDX-ID license template.[software-name] in the SPDX-ID license template.fix command needs to insert a license header, if both license and SPDX-ID are specified, license wins.pattern is an optional regexp. You don’t need this if all the file headers are the same as license or the license of SPDX-ID, otherwise you need to compose a pattern that matches your existing license texts so that license-eye won't complain about the existing license headers. If you want to replace your existing license headers, you can compose a pattern that matches your existing license headers, and modify the content to what you want to have, then license-eye header fix would rewrite all the existing license headers to the wanted content.paths are the path list that will be checked (and fixed) by license-eye, default is ['**']. Formats like **/*.md and **/bin/** are supported.paths-ignore are the path list that will be ignored by license-eye. By default, .git and the content in .gitignore will be inflated into the paths-ignore list.on-failure, always or never. Options other than never require the environment variable GITHUB_TOKEN to be set.license-location-threshold specifies the index threshold where the license header can be located.language is an optional configuration. You can set the language license header comment style. If it doesn't exist, it will use the default configuration at the languages.yaml. An example is to use block comment style for Go codes.extensions are the files with these extensions which the configuration will take effect.filenames are the specified files which the configuration will take effect.comment_style_id set the license header comment style, it's the id at the styles.yaml.dependency section is configurations for resolving dependencies' licenses.files are the files that declare the dependencies of a project, typically, go.mod in Go project, pom.xml in maven project, and package.json in NodeJS project. If it‘s a relative path, it’s relative to the .licenserc.yaml.name of the dependency, The name is different for different projects, PackagePath in Go project, GroupID:ArtifactID in maven project, PackageName in NodeJS project. You can use file pattern as described in the doc.version of the dependency, comma seperated string (such as 1.0,2.0,3.0), if this is empty, it means all versions of the dependency.75.pom.xml with compile scope but don‘t distribute them in package. (Note that non-compile scope dependencies are automatically excluded so you don’t need to put them here).1994, or 1994-2023.require_fsf_free is true, only dependency licenses marked as FSF Free/Libre in the built-in compatibility matrices are considered compatible. Licenses not marked FSF-free will be treated as incompatible even if otherwise listed as compatible. This can also be enabled via the CLI flag --fsf-free (-f).require_osi_approved is true, only dependency licenses marked as OSI-approved in the built-in compatibility matrices are considered compatible. Licenses not marked OSI-approved will be treated as incompatible even if otherwise listed as compatible. This can also be enabled via the CLI flag --osi-approved (-o).NOTE: When the SPDX-ID is Apache-2.0 and the owner is Apache Software foundation, the content would be a dedicated license specified by the ASF, otherwise, the license would be the standard one.
The header check command theoretically supports all kinds of file types, while the supported file types of header fix command can be found in this YAML file. In the YAML file, if the language has a non-empty property comment_style_id, and the comment style id is declared in the comment styles file, then the language is supported by fix command.
