Automated Dependency Updates for Gradle

Categories: java

Renovate supports updating Gradle dependencies.

File Matching

By default, Renovate will check any files matching any of the following regular expressions:

\.gradle(\.kts)?$
(^|/)gradle\.properties$
(^|/)gradle/.+\.toml$
(^|/)buildSrc/.+\.kt$
\.versions\.toml$
(^|/)versions.props$
(^|/)versions.lock$

For details on how to extend a manager's fileMatch value, please follow this link.

Supported datasources

This manager supports extracting the following datasources: maven.

Default config

{
  "fileMatch": [
    "\\.gradle(\\.kts)?$",
    "(^|/)gradle\\.properties$",
    "(^|/)gradle/.+\\.toml$",
    "(^|/)buildSrc/.+\\.kt$",
    "\\.versions\\.toml$",
    "(^|/)versions.props$",
    "(^|/)versions.lock$"
  ],
  "timeout": 600,
  "versioning": "gradle"
}

Additional Information

The gradle manager uses a custom parser written in JavaScript, similar to many others managers. It does not call gradle directly in order to extract a list of dependencies.

Updating lockfiles

The gradle manager supports gradle lock files in .lockfile artifacts, as well as lock files used by the gradle-consistent-versions plugin. During lock file maintenance, renovate calls ./gradlew :dependencies --write-locks on the root project and subprojects. For regular dependency updates, renovate automatically updates lock state entries via the --update-locks command line flag.

As the output of these commands can be very large, any text other than errors (in stderr) is discarded.

Dependency verification

If Renovate finds a gradle/verification-metadata.xml file and either <verify-metadata>true</verify-metadata> or <verify-signatures>true</verify-signatures> (or both), it updates the content by using the gradle --write-verification-metadata <hashTypes> dependencies command. Renovate will check the file for existing hash types (like sha256) and use them as <hashTypes>.

Warning

Gradle allows verification metadata to use the md5 and sha1 algorithms. Because those algorithms are prone to collision attacks, Renovate ignores them. If Renovate encounters hashes that are generated with md5 or sha1 algorithms, Renovate uses sha256 instead.
