Example 2 with LocalProperties

use of org.apache.tools.ant.property.LocalProperties in project ant by apache.

the class Target method execute.

/**
 * 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.
 *
 * @exception BuildException if any of the tasks fail or if a data type
 *                           configuration fails.
 *
 * @see #performTasks()
 * @see #setIf(String)
 * @see #setUnless(String)
