## Class StartParameter

- java.lang.Object
- - org.gradle.logging.LoggingConfiguration
  - - org.gradle.StartParameter

- All Implemented Interfaces:
    Serializable

      public class StartParameter
      extends org.gradle.logging.LoggingConfiguration
      implements Serializable

  `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 pass a `StartParameter` instance to `GradleLauncher.newInstance(StartParameter)` when you create a new Gradle instance.

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