Module: Dependabot::Gradle::FileUpdater::Wrapper::ExecutingVersionDetector

Extended by:
T::Sig
Defined in:
lib/dependabot/gradle/file_updater/wrapper/executing_version_detector.rb

Overview

Detects the Gradle version that will actually execute the wrapper task.

The wrapper task runs under whatever Gradle the project currently resolves to (the OLD distribution), not the target version. Knowing that version lets CommandBuilder decide which version-gated CLI flags are safe to pass.

Constant Summary collapse

DISTRIBUTION_URL_VERSION_REGEX =

Matches the version embedded in a Gradle distribution URL, e.g. services.gradle.org/distributions/gradle-9.5.0-bin.zip Anchored to the ‘gradle-<version>-(bin|all).zip` filename so host/port numbers in custom mirror URLs are never mistaken for the version. The captured token is validated with Version.correct? so non-version matches (and RC/milestone names) are handled safely.

T.let(
  /gradle-(?<version>.+?)-(?:bin|all)\.zip/,
  Regexp
)
GRADLE_VERSION_OUTPUT_REGEX =

Matches the version printed by ‘gradle –version`, e.g. “Gradle 9.2.1”.

T.let(/^Gradle\s+(?<version>\d+(?:\.\d+){1,2}(?:-[\w.]+)?)/, Regexp)
