Class Exit

  • All Implemented Interfaces:
    java.lang.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

      • 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).

        execute in class Task
        Throws:
        BuildException - on error
