/**
 * <p>In Maven, repositories are locations where project artifacts (such as JAR files, POM files, and other
 * resources) are stored and retrieved. There are two primary types of repositories:
 * {@linkplain LocalRepository local repositories} and
 * {@linkplain RemoteRepository remote repositories}.</p>
 *
 * <h2>Repository Resolution Process</h2>
 *

   *
   * <p>Why <i>not</i> just add {@code SuppressWarnings}? The problem is that this method is
   * typically useful for {@code return} statements. That leaves the code with two options: Either
   * add the suppression to the whole method (which turns off checking for a large section of code),
   * or extract a variable, and put the suppression on that. However, a local variable typically

		// Range can only be numeric.
		{":9000", []string{"/export1{a...z}"}, false},
		// Duplicate disks not allowed.
		{":9000", []string{"/export1{1...32}", "/export1{1...32}"}, false},
		// Same host cannot export same disk on two ports - special case localhost.
		{":9001", []string{"http://localhost:900{1...2}/export{1...64}"}, false},
		// Valid inputs.
		{":9000", []string{"/export1"}, true},

This ensures we can setup the network configuration and start Ztunnel.
Only once those two conditions are met does the CNI plugin return success - effectively allowing our plugin to block Pod scheduling until we are ready.
Otherwise, the CNI plugin will continually be retried, blocking Pod startup until it succeeds.
