This is a GitHub Action that will generate a complete dependency graph for a Maven project and submit the graph to the GitHub repository so that the graph is complete and includes all the transitive dependencies.

The action will invoke maven using the com.github.ferstl:depgraph-maven-plugin:4.0.2 plugin to generate JSON output of the complete dependency graph, which is then processed and submitted using the Dependency Submission Toolkit to the GitHub repository.

Warning The dependency submission APIs and toolkit are still currently in beta and as such subject to changes in future releases.

As of version 3.0.0 this action now support Maven multi-module projects as well as additional Maven configuration parameters.

For this action to work properly, you must have the Maven available on PATH (mvn) or using a mvnw Maven wrapper in your maven project directory. Maven will need to be configured to be able to access and pull your dependencies from whatever sources you have defined (i.e. a properly configured settings.xml or all details provided in the POM).

Custom maven settings.xml can now be specified as an input parameter to the action.

This action writes informations in the repository dependency graph, so if you are using the default token, you need to set the contents: write permission to the workflow or job. If you are using a personal access token, this token must have the repo scope. (API used by this action)

• directory - The directory that contains the pom.xml that will be used to generate the dependency graph from. Defaults to the github.workspace which is where the source will check out to by default when using actions/checkout .

• token - The GitHub token that will be used to submit the generated dependency snapshot to the repository. Defaults to the github.token from the actions environment.

• settings-file - An optional path to a Maven settings.xml file that you want to use to provide additional configuration to Maven.

• ignore-maven-wrapper - An optional true/false flag parameter to ignore the Maven wrapper (if present) in the maven project directory and instead use the version of Maven from the PATH. This is set to false by default to use the wrapper if one is present.

• maven-args - An optional string value (space separated) options to pass to the maven command line when generating the dependency snapshot. This is empty by default.

• snapshot-include-file-name: Optional flag to control whether or no the path and file name of the pom.xml is provided with the snapshot submission. Defaults to true so as to create a link to the repository file from the dependency tree view, but at the cost of losing the POM artifactId when it renders.

• snapshot-dependency-file-name: An optional user control file path to the POM file, requires snapshot-include-file-name to be true for the value to be submitted.

Generating and submitting a dependency snapshot using the defaults:

- name: Submit Dependency Snapshot
  uses: advanced-security/maven-dependency-submission-action@v3

Upon success it will generate a snapshot captured from Maven POM like;

There are experimental command line clients, Linux only for now that will provide the same functionality as the GitHub Action but can be embedded into your existing CI tooling and invoked from the commandline to upload a dependency snapshot.

You can obtain the executables from the latest actions workflow run https://github.com/advanced-security/maven-dependency-submission-action/actions/workflows/publish_executables.yml.

Run the command line tool with the --help option to display all the possible configuration options;

To develop on this project, a Codespace has been provided that will provide all the necessary tools and installation of a JDK and Maven for the test suite to pass. Just open a Codespace and you can start to develop in the quickest possible timeframe.

The codebase is in TypeScript to make it easier for maintenance.

The source code lives under src and the Action is provided in the src/index.ts file.

To build the software npm has been configured with scripts for test and build script to validate any work before publishing the action code.
