* feat(manager): pass extracted constraints to updateArtifacts `extractedConstraints` were collected during extraction but only ever read by `fetch.ts` for the lookup. At artifact time every manager had to derive the same tool constraints a second time, and when the updated package file no longer carried the constraint there was nothing to fall back to. `generateBranchConfig()` now merges the `extractedConstraints` of all upgrades of a branch onto the branch config, which reaches `updateArtifacts()` through `patchConfigForArtifactsUpdate()`. `UpdateArtifactsConfig` declares the field and documents what it contains. The new `resolveToolConstraint()` helper implements the ladder once: user `constraints` > an optional artifact-time derivation > the extracted value. The derivation is ranked above the extracted value on purpose: it reads the package files as the branch changed them, so poetry (python is an updatable dependency there), composer, pipenv (`pipenv` can be a dev package) and pep621 (`requires-python` is an updatable dependency) would otherwise regress to a stale constraint. pipenv, pep621 uv/pdm, poetry and composer are migrated to the helper and keep their derivation. Behaviour change: these managers now use the extract-time constraint as a last resort instead of running unconstrained, for example on lock file maintenance where pipenv deletes `Pipfile.lock` before deriving. `execute-post-upgrade-commands.ts` is unaffected: it reads `upgrade.constraints` per upgrade, and the extracted values are kept in a separate field rather than folded into `constraints`, so post-upgrade task tool constraints still come from user config only. Not migrated, because their constraints are never extracted, so the fallback would be dead code: bundler (`ruby`/`bundler`), pixi (`pixi`), pep621 uv (`required-version`) and npm's node ladder, whose last step already reads `package.json` engines. * refactor(manager): resolve tool constraints through resolveToolConstraint() Every manager now obtains the constraint of a tool it runs through `resolveToolConstraint()` instead of reading `config.constraints` itself, so the precedence "user config, then a value derived from the updated files, then the constraints collected during extraction" applies everywhere. The helper treats an empty string as not set at every step and accepts the `PostUpdateConfig` shape, whose `constraints` may be `null`. Behaviour changes that go beyond the new fallback to extracted constraints: - `mix` applies its hardcoded erlang default only after the extracted constraint, so an erlang version collected at extraction can win over it. - `kustomize` decides `HELM_EXPERIMENTAL_OCI` from the fully resolved helm constraint; `generateHelmEnvs()` takes that value instead of the config. - `npm` (yarn): an upgrade of yarn without a new value now consults the user constraint before deriving one from package.json or the lock file. - The "Using <tool> constraint from config" debug lines in bundler, composer, copier and pip-compile are gone, as the helper is the only reader of the config now. Helpers that read the config synchronously became async: bundler `getBundlerConstraint()`, copier `getPythonVersionConstraint()` and `getCopierVersionConstraint()`, pip-compile `get*VersionConstraint()` and `getToolVersionConstraint()`, gomod `deriveGoToolchainConstraints()` and `getUpdateImportPathCmds()`, mise `getMiseLockToolConstraints()`. composer `getPhpConstraint()` is removed. Each converted manager has a test showing the extracted constraint reaching the executed tool, and, where a derive callback exists, that the derived value still wins over it. * refactor(linters): add prefer-resolve-tool-constraint rule Reports member reads and destructuring of `constraints` and `extractedConstraints` from a manager config in `lib/modules/manager/**`, so that tool constraints are resolved through `resolveToolConstraint()` in `lib/modules/manager/util.ts` only. Writes and the same properties on package files, which extraction has to populate, are not reported. The helper itself and spec files are exempt in `.oxlintrc.json`. * refactor(manager): inline thin resolveToolConstraint wrappers Drop copier/utils.ts and the pip-compile getPipToolsVersionConstraint / getUvVersionConstraint helpers, which only forwarded to resolveToolConstraint(). Callers now call it directly. * docs(development): note lock file maintenance in tool constraints section * refactor(manager): address review on tool constraint resolution composer only runs extractConstraints() when a user constraint is missing, via Lazy. UpdateArtifactsConfig no longer re-declares constraints and extractedConstraints, which ToolConstraintsConfig already provides.
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.
Executing the Gradle Wrapper
Renovate will only execute the Gradle Wrapper (via ./gradlew or gradlew.bat) if the self-hosted administrator configures allowedUnsafeExecutions to include the gradleWrapper option.
This is required due to possible supply chain security attack vectors that can occur with the Gradle Wrapper being executed.
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
Renovate supports Gradle's dependency verification functionality to ensure that checksums are calculated for your dependencies.
!!! note This requires your self-hosted administrator to allow the Gradle Wrapper to execute.
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 ./gradlew --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.
