Package org.gradle

## Class StartParameter

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

- All Implemented Interfaces:
    `java.io.Serializable`, `LoggingConfiguration`, `ParallelismConfiguration`

      public class StartParameter
      extends java.lang.Object
      implements LoggingConfiguration, ParallelismConfiguration, java.io.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 can obtain an instance of a `StartParameter` by either creating a new one, or duplicating an existing one using `newInstance()` or `newBuild()`.
