All Implemented Interfaces:
  `Cloneable`

public class JDependTask extends Task
Runs JDepend tests.

JDepend is a tool to generate design quality metrics for each Java package. It has been initially created by Mike Clark. JDepend can be found at https://github.com/clarkware/jdepend. The current implementation spawn a new Java VM.

## Constructor Details

### JDependTask

public JDependTask()

## Method Details

### setIncluderuntime

public void setIncluderuntime(boolean b)
If true, include jdepend.jar in the forked VM.

Parameters:
  `b` - include ant run time yes or no
Since:
  Ant 1.6

### setTimeout

public void setTimeout(Long value)
Set the timeout value (in milliseconds).

If the operation is running for more than this value, the jdepend will be canceled. (works only when in 'fork' mode).

Parameters:
  `value` - the maximum time (in milliseconds) allowed before declaring the test as 'timed-out'
See Also:
  - `setFork(boolean)`

### getTimeout

public Long getTimeout()

Returns:
  the timeout value

### setOutputFile

public void setOutputFile(File outputFile)
The output file name.

Parameters:
  `outputFile` - the output file name

### getOutputFile

public File getOutputFile()

Returns:
  the output file name

### setHaltonerror

public void setHaltonerror(boolean haltonerror)
Whether or not to halt on failure. Default: false.

Parameters:
  `haltonerror` - the value to set

### getHaltonerror

public boolean getHaltonerror()

Returns:
  the value of the haltonerror attribute

### setFork

public void setFork(boolean value)
If true, forks into a new JVM. Default: false.

Parameters:
  `value` - `true` if a JVM should be forked, otherwise `false`

### getFork

public boolean getFork()

Returns:
  the value of the fork attribute

### setJvm

public void setJvm(String value)
The command used to invoke a forked Java Virtual Machine. Default is `java`. Ignored if no JVM is forked.

Parameters:
  `value` - the new VM to use instead of `java`
See Also:
  - `setFork(boolean)`

### createSourcespath

@Deprecated public Path createSourcespath()
Deprecated.
since 1.6.x.

Adds a path to class code to analyze.

Returns:
  a classes path

### getClassespath

public Path getClassespath()
Gets the classespath.

Returns:
  the classes path

### setDir

public void setDir(File dir)
The directory to invoke the VM in. Ignored if no JVM is forked.

Parameters:
  `dir` - the directory to invoke the JVM from.
See Also:
  - `setFork(boolean)`

### getDir

public File getDir()

Returns:
