How to update Gradle itself?

[jmfayard]

Context: buildSrcVersions is a Gradle plugin that makes it easier to manage your dependencies inside your IDE. It extracts all your dependencies and search for available dependencies updates.

Available since 0.6.0

$ ./gradlew refreshVersions add in gradle.properties:

// gradle.properties
version.gradleLatestVersion=5.6.2

Available since: 0.4.0

The standard way to update gradle is to edit the file: gradle/wrapper/gradle-wrapper.properties

The buildSrcVersions also looks for what is the latest available release for Gradle itself.

object Versions {
   // ...

    const val gradleLatestVersion: String = "5.1.1"
}

You can leverage this information by configuring the wrapper task:

Groovy:

// ./build.gradle
wrapper {
}

Kotlin:

// ./build.gradle.kts
tasks.withType<Wrapper> {
    distributionType = Wrapper.DistributionType.ALL
    // with buildSrcVersions
    gradleVersion = Versions.gradleLatestVersion   
    // with refreshVersions
    gradleVersion = findProperty("gradleLatestVersion") as? String ?: gradle.gradleVersion
}

Then this will automatically update Gradle to the latest available release

$ ./gradlew wrapper
