Package: org.gradle

## [Java] Class StartParameter

- org.gradle.StartParameter

- All Implemented Interfaces and Traits:
    LoggingConfiguration, Serializable

      public class StartParameter
      extends Object

  `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.
