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

setMessage

public void setMessage(java.lang.String value)

A message giving further information on why the build exited.

Only fail if a property of the given name exists in the current project.

Parameters:

c - property name

public void setUnless(java.lang.String c)

Only fail if a property of the given name does not exist in the current project.

Parameters:

c - property name

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

addText

public void addText(java.lang.String msg)

Set a multiline message.

Parameters:

msg - the message to display
