- Method Detail
  - getGradleVersion
```
String getGradleVersion()
```
    Returns the current Gradle version.
    
    Returns:
    
    The Gradle version. Never returns null.
  - getGradleUserHomeDir
```
File getGradleUserHomeDir()
```
    Returns the Gradle user home directory. This directory is used to cache downloaded resources, compiled build scripts and so on.

    The user home directory. Never returns null.
  - getGradleHomeDir
```
@Nullable
File getGradleHomeDir()
```
    Returns the Gradle home directory, if any. This directory is the directory containing the Gradle distribution executing this build.
    When using the “Gradle Daemon”, this may not be the same Gradle distribution that the build was started with. If an existing daemon process is running that is deemed compatible (e.g. has the desired JVM characteristics) then this daemon may be used instead of starting a new process and it may have been started from a different “gradle home”. However, it is guaranteed to be the same version of Gradle. For more information on the Gradle Daemon, please consult the user guide.
    
    Returns:
    
    The home directory. May return null.
  - getParent
```
@Nullable
Gradle getParent()
```
    Returns the parent build of this build, if any.
    
    Returns:
    
    The parent build. May return null.

  - projectsEvaluated
```
void projectsEvaluated(Action<? super Gradle> action)

    3.4
  - buildFinished
```
void buildFinished(Closure closure)

    Adds a closure to be called when the build is completed. All selected tasks have been executed. A BuildResult instance is passed to the closure as a parameter.
    
    Parameters:
    
    closure - The closure to execute.
  - buildFinished
```
void buildFinished(Action<? super BuildResult> action)
```
    Adds an action to be called when the build is completed. All selected tasks have been executed.

  - addBuildListener
```
void addBuildListener(BuildListener buildListener)
```
    Adds a BuildListener to this Build instance. The listener is notified of events which occur during the execution of the build.
    
    Parameters:
    
    buildListener - The listener to add.
  - addListener
```
void addListener(Object listener)
```
    Adds the given listener to this build. The listener may implement any of the given listener interfaces:
    Parameters:
    
    listener - The listener to add. Does nothing if this listener has already been added.
  - removeListener
```
void removeListener(Object listener)
```
    Removes the given listener from this build.
    
    Parameters:
    
    listener - The listener to remove. Does nothing if this listener has not been added.
  - useLogger
```
void useLogger(Object logger)
```
    Uses the given object as a logger. The logger object may implement any of the listener interfaces supported by addListener(Object).
    Each listener interface has exactly one associated logger. When you call this method with a logger of a given listener type, the new logger will replace whichever logger is currently associated with the listener type. This allows you to selectively replace the standard logging which Gradle provides with your own implementation, for certain types of events.
    
    Parameters:
    
    logger - The logger to use.
  - getGradle
```
Gradle getGradle()
```
    Returns this Gradle instance. This method is useful in init scripts to explicitly access Gradle properties and methods. For example, using gradle.parent can express your intent better than using parent. This property also allows you to access Gradle properties from a scope where the property may be hidden, such as, for example, from a method or closure.
    
    Returns:
    
    this. Never returns null.
  - getIncludedBuilds
```
@Incubating
Collection<IncludedBuild> getIncludedBuilds()
```
    Returns the included builds for this build.
    
    Since:
    
    3.1
  - includedBuild
```
@Incubating
IncludedBuild includedBuild(String name)
                                 throws UnknownDomainObjectException
```
    Returns the included build with the specified name for this build.
    
    Throws:
    
    UnknownDomainObjectException - when there is no build with the given name
    
    Since:
    
    3.1
