      true if the target does depend on the named target
      Since:
      Ant 1.6
    • setIf

      public void setIf(String property)
      Sets the "if" condition to test on execution. This is the name of a property to test for existence - if the property is not set, the task will not execute. The property goes through property substitution once before testing, so if property foo has value bar, setting the "if" condition to ${foo}_x will mean that the task will only execute if property bar_x is set.
      Parameters:
      property - The property condition to test on execution. May be null, in which case no "if" test is performed.
    • getIf

      public String getIf()
      Returns the "if" property condition of this target.
      Returns:
      the "if" property condition or null if no "if" condition had been defined.
      Since:
      1.6.2
    • setIf

      public void setIf(Condition condition)
      Same as setIf(String) but requires a Condition instance
      Parameters:
      condition - Condition
      Since:
      1.9
    • setUnless

      public void setUnless(String property)
      Sets the "unless" condition to test on execution. This is the name of a property to test for existence - if the property is set, the task will not execute. The property goes through property substitution once before testing, so if property foo has value bar, setting the "unless" condition to ${foo}_x will mean that the task will only execute if property bar_x isn't set.
      Parameters:
      property - The property condition to test on execution. May be null, in which case no "unless" test is performed.
    • getUnless

      public String getUnless()
      Returns the "unless" property condition of this target.
      Returns:
      the "unless" property condition or null if no "unless" condition had been defined.
      Since:
      1.6.2
    • setUnless

      public void setUnless(Condition condition)
      Same as setUnless(String) but requires a Condition instance
      Parameters:
      condition - Condition
      Since:
      1.9
    • setDescription

      public void setDescription(String description)
      Sets the description of this target.
      Parameters:
      description - The description for this target. May be null, indicating that no description is available.
    • getDescription

      public String getDescription()
      Returns the description of this target.
      Returns:
      the description of this target, or null if no description is available.
    • toString

      public String toString()
      Returns the name of this target.
      Overrides:
      toString in class Object
      Returns:
      the name of this target, or null if the name has not been set yet.
    • execute

      public void execute() throws BuildException
      Executes the target if the "if" and "unless" conditions are satisfied. Dependency checking should be done before calling this method, as it does no checking of its own. If either the "if" or "unless" test prevents this target from being executed, a verbose message is logged giving the reason. It is recommended that clients of this class call performTasks rather than this method so that appropriate build events are fired.
      Throws:
      BuildException - if any of the tasks fail or if a data type configuration fails.
      See Also:
    • performTasks

      public final void performTasks()
      Performs the tasks within this target (if the conditions are met), firing target started/target finished messages around a call to execute.
