# StartParameter

open class StartParameter : LoggingConfiguration, ParallelismConfiguration, Serializable(source)

`StartParameter` defines the configuration used by a Gradle instance to execute a build. The properties of `StartParameter` generally correspond to the command-line options of Gradle.

You can obtain an instance of a `StartParameter` by either creating a new one, or duplicating an existing one using newInstance or newBuild.
