Class Exit

java.lang.Object

org.apache.tools.ant.ProjectComponent

org.apache.tools.ant.Task

org.apache.tools.ant.taskdefs.Exit

All Implemented Interfaces:

Cloneable

public class Exit
extends Task

Exits the active build, giving an additional message if available. The if and unless attributes make the failure conditional -both probe for the named property being defined. The if tests for the property being defined, the unless for a property being undefined. If both attributes are set, then the test fails only if both tests are true. i.e.

fail := defined(ifProperty) && !defined(unlessProperty)

A single nested<condition> element can be specified instead of using if/unless (a combined effect can be achieved using isset conditions).

Since:

Ant 1.2

Method Details

setMessage

public void setMessage(String value)

A message giving further information on why the build exited.

Parameters:

value - message to output

setIf

public void setIf(Object c)

Only fail if the given expression evaluates to true or the name of an existing property.

Parameters:

c - property name or evaluated expression

Since:

Ant 1.8.0

setIf

public void setIf(String c)

Only fail if the given expression evaluates to true or the name of an existing property.

Parameters:

c - property name or evaluated expression

setUnless

public void setUnless(Object c)

Only fail if the given expression evaluates to false or tno property of the given name exists.

Parameters:

c - property name or evaluated expression

Since:

Ant 1.8.0

setUnless

public void setUnless(String c)

Only fail if the given expression evaluates to false or tno property of the given name exists.

Parameters:

c - property name or evaluated expression

setStatus

public void setStatus(int i)

Set the status code to associate with the thrown Exception.

Parameters:

i - the int status

execute

public void execute()
             throws BuildException

Throw a BuildException to exit (fail) the build. If specified, evaluate conditions: A single nested condition is accepted, but requires that the if/unless attributes be omitted. If the nested condition evaluates to true, or the ifCondition is true or unlessCondition is false, the build will exit. The error message is constructed from the text fields, from the nested condition (if specified), or finally from the if and unless parameters (if present).

Overrides:

execute in class Task

Throws:

BuildException - on error

addText

public void addText(String msg)

Set a multiline message.

Parameters:

msg - the message to display

createCondition

public ConditionBase createCondition()

Add a condition element.

Returns:

ConditionBase.

Since:

Ant 1.6.2
