Maven Check Versions

This is a python package designed for analyzing Maven pom files. It checks the versions of dependencies in a project and identifies the latest available versions in repositories. It is especially useful in CI/CD environments, where maintaining consistency and up-to-date dependencies is crucial.

See https://pypi.org/project/maven-check-versions for more details.

Features

• Dependency Analysis: Parses Maven POM files to analyze dependencies and plugins.
• Version Checking: Identifies outdated dependencies and checks versions against customizable thresholds.
• Artifact Search: Finds specific artifacts using groupId:artifactId:version format.
• Repository Support: Integrates with HTTP-based Maven repositories, including REST services.
• Module Processing: Processes nested modules in Maven projects.
• Caching: Caches results for faster rechecks with multiple cache backends.
• Logging: Provides configurable logging for detailed analysis.
• Command-Line Interface: Easily integrates into CI/CD pipelines.
• Vulnerability Checking: Checks dependencies for known vulnerabilities using OSS Index.

Configuration

You can customize the tool’s behavior using a configuration file maven_check_versions.yml. The following settings can be adjusted:

• SSL Verification: Enable or disable SSL verification for HTTP requests.
• Cache Preferences: Control cache duration and behavior.
• Repository Settings: Define base URLs, authentication, and paths for repositories.
• Logging Preferences: Specify log levels and file paths.
• Vulnerability Checking: Configure checks for known vulnerabilities in dependencies.

Cache Configuration

The tool supports multiple cache backends:

• JSON (default): Stores cache data in a local JSON file specified by cache_file.
• Redis: Uses a Redis server for caching.
• Tarantool: Uses a Tarantool server for caching.
• Memcached: Uses a Memcached server for caching.

Vulnerability Checking Configuration

To enable vulnerability checking, set oss_index to true in the vulnerability section of the configuration file. This feature uses the OSS Index service to identify known vulnerabilities in your dependencies. You will need to provide your OSS Index username and API token, which you can obtain by signing up for a free account at https://ossindex.sonatype.org/.

Example configuration:

Vulnerability scanning will:

1. Check all dependencies against OSS Index
2. Fail build if any vulnerability with CVSS ≥7.0 found
3. Skip checks for test components

vulnerability:
  oss_index: true
  oss_index_url: "https://ossindex.sonatype.org/api/v3/component-report"
  oss_index_user: "OSS_INDEX_USER"
  oss_index_token: "OSS_INDEX_TOKEN"
  oss_index_batch_size: 128
  oss_index_keep_safe: false
  fail_score: 7
  skip_no_versions: false
  skip_checks: [ "junit:junit:*" ]
  cache_backend: "json"
