Class StartParameter

    java.lang.Object
      org.gradle.StartParameter

    public class StartParameter

extends java.lang.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 pass a `StartParameter` instance to `Gradle.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()`.

Constructor Detail

### StartParameter

    public StartParameter()

  Creates a `StartParameter` with default values. This is roughly equivalent to running Gradle on the command-line with no arguments.

Method Detail

### newInstance

    public StartParameter newInstance()

  Duplicates this `StartParameter` instance.

  Returns:
    the new parameters.

### newBuild

    public StartParameter newBuild()

  Creates the parameters for a new build, using these parameters as a template. Copies the environmental properties from this parameter (eg gradle user home dir, etc), but does not copy the build specific properties (eg task names).

  Returns:
    The new parameters.

### equals

    public boolean equals(java.lang.Object obj)

  Overrides:
    `equals` in class `java.lang.Object`

    public int hashCode()

  Overrides:
    `hashCode` in class `java.lang.Object`

### getBuildFile

    public java.io.File getBuildFile()

  Returns the build file to use to select the default project. Returns null when the build file is not used to select the default project.

  Returns:
    The build file. May be null.

### setBuildFile

    public void setBuildFile(java.io.File buildFile)

  Sets the build file to use to select the default project. Use null to disable selecting the default project using the build file.

  Parameters:
    `buildFile` - The build file. May be null.

### getGradleHomeDir

    public java.io.File getGradleHomeDir()

### setGradleHomeDir

    public void setGradleHomeDir(java.io.File gradleHomeDir)

### getBuildScriptSource

    public ScriptSource getBuildScriptSource()

  Returns the `ScriptSource` to use for the build file for this build. Returns null when the default build file(s) are to be used. This source is used for all projects included in the build.

  Returns:
    The build file source, or null to use the defaults.

### getSettingsScriptSource

    public ScriptSource getSettingsScriptSource()

  Returns the `ScriptSource` to use for the settings script for this build. Returns null when the default settings script is to be used.
