21     * We're not doing that yet though because Gradle takes more time to process .kts files (at the
22     * time of writing, adding a .kts file adds roughly 10 addition seconds to build startup time).

24     * getGradleVersion() is in a format of X.Y.Z-rc-1 / X.Y.Z. Kotlin dsl jar always drops the
25     * "-rc-1" suffix of the version, thus we need additional substring logic.
