Gradle --show-version

Since Gradle 5.0, GradleVersion is no longer accessible. Use

project.getGradle().getGradleVersion()

instead.

For example:

task printGradleVersion() {
    def gradleVersion = project.getGradle().getGradleVersion()
    println "Gradle version: $gradleVersion"
}

See the docs for more information.

Just add this line at the very beginning of build.gradle script:

println GradleVersion.current().prettyPrint()

It won't stop the build and print all the required info (I hope so). Unfortunately haven't found docs for this class.

EDIT

Note for newer versions of Gradle: As prettyPrint is dropped from some gradle version, you can just add this line at the very beginning of build.gradle script:

println GradleVersion.current().getVersion() + " - " + GradleVersion.current().getBuildTime() + " - " + GradleVersion.current().getRevision() + GradleVersion.current().isSnapshot() ? " - is snapshot" : ""

You can use:

gradle -v

This is the output:

If you use it in CI environment, it doesn't stop the build.
