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

# 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.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: [email protected]
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.

docker run -it --rm -v $(pwd):/github/workspace apache/skywalking-eyes header fixFor 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.

incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only

headersection 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- The SPDX ID of the license, it’s convenient when your license is standard SPDX license, so that you can simply specify this identifier without copying the whole license
contentorpattern. This will be used as the content whenfixcommand needs to insert a license header. - The copyright owner to replace the
[owner]in theSPDX-IDlicense template. - The copyright software name to replace the
[software-name]in theSPDX-IDlicense template. - If you are not using the standard license text, you can paste your license text here, this will be used as the content when
fixcommand needs to insert a license header, if bothlicenseandSPDX-IDare specified,licensewins. - The
patternis an optional regexp. You don’t need this if all the file headers are the same aslicenseor the license ofSPDX-ID, otherwise you need to compose a pattern that matches your existing license texts so thatlicense-eyewon't complain about the existing license headers. If you want to replace your existing license headers, you can compose apatternthat matches your existing license headers, and modify thecontentto what you want to have, thenlicense-eye header fixwould rewrite all the existing license headers to the wantedcontent. - The
pathsare the path list that will be checked (and fixed) by license-eye, default is['**']. Formats like**/*.md and**/bin/**are supported. - The
paths-ignoreare the path list that will be ignored by license-eye. By default,.gitand the content in.gitignorewill be inflated into thepaths-ignorelist. - On what condition License-Eye will comment the check results on the pull request,
on-failure,alwaysornever. Options other thanneverrequire the environment variableGITHUB_TOKENto be set. - The
license-location-thresholdspecifies the index threshold where the license header can be located. - The
languageis an optional configuration. You can set the language license header comment style. If it doesn't exist, it will use the default configuration at thelanguages.yaml. An example is to use block comment style for Go codes. - Specify the programming language identifier. You can set different configurations for multiple languages.
- The
extensionsare the files with these extensions which the configuration will take effect. - The
filenamesare the specified files which the configuration will take effect. - The
comment_style_idset the license header comment style, it's theidat thestyles.yaml. - The
dependencysection is configurations for resolving dependencies' licenses. - The
filesare the files that declare the dependencies of a project, typically,go.modin Go project,pom.xmlin maven project, andpackage.jsonin NodeJS project. If it's a relative path, it's relative to the.licenserc.yaml. - Declare the licenses which cannot be identified by this tool.
- The
nameof the dependency, The name is different for different projects,PackagePathin Go project,GroupID:ArtifactIDin maven project,PackageNamein NodeJS project. You can use file pattern as described in the doc. - The
versionof the dependency, comma seperated string (such as1.0,2.0,3.0), if this is empty, it means all versions of the dependency. - The SPDX ID of the dependency license.
- The minimum percentage of the file that must contain license text for identifying a license, default is
75. - The dependencies that should be excluded when analyzing the licenses, this is useful when you declare the dependencies in
pom.xmlwithcompilescope but don't distribute them in package. (Note that non-compilescope dependencies are automatically excluded so you don't need to put them here). - The transitive dependencies brought by <23> should be recursively excluded when analyzing the licenses, currently only maven project supports this.
- The copyright year of the work, if it's empty, it will be set to the current year. If you don't want to update the license year anually, you can set this to the year of the first publication of your work, such as
1994, or1994-2023.
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.
