Spock order tests by packages

He,everyone! My tests are running by jenkins from general package. Can I set test package in spock which will be runnning first and if in this package will not passed any of test the other tests should be skipped. I saw examples like this:

import org.junit.runner.RunWith;
import org.junit.runners.Suite;    
@RunWith(Suite.class)    
@Suite.SuiteClasses({TestJunit1.class, TestJunit2.class})    
  public class JunitTestSuite {   
  }  

But maybe spock has solution where I can use packages instead enum of each classes, because I have many test classes in other many packages. Also after i used runner

import org.junit.runner.JUnitCore;
import org.junit.runner.Result;
import org.junit.runner.notification.Failure;

public class TestRunner {
  public static void main(String[] args) {
    Result result = JUnitCore.runClasses(JunitTestSuite.class);    
      for (Failure failure : result.getFailures()) {
        System.out.println(failure.toString());
      }         
      System.out.println(result.wasSuccessful());
   }
} 

The main thread doesnt stop. I dont know why. I want to do something like that:

import org.junit.runner.RunWith;
import org.junit.runners.Suite;    
@RunWith(Suite.class)    
@Suite.SuiteClasses({com.example.test.*.class})    
   public class JunitTestSuiteFirst {   
   }  

---

import org.junit.runner.RunWith;
import org.junit.runners.Suite;        
@RunWith(Suite.class)        
@Suite.SuiteClasses({com.example.otherTest.*.class, com.example.otherTests2.*.class})        
   public class JunitTestSuiteFirst {   
    }  

---

import org.junit.runner.JUnitCore;
import org.junit.runner.Result;
import org.junit.runner.notification.Failure;

public class TestRunner {
   public static void main(String[] args) {
      Result result = JUnitCore.runClasses(JunitTestSuite.class);    
      for (Failure failure : result.getFailures()) {
         System.out.println(failure.toString());
      }
      if(result.wasSuccessful()){
         JUnitCore.runClasses(JunitTestSuite.class);
      }else {
         System.out.println("Build failed");
      }
   }
} 

Or maybe exist more simple solution of this task. Thanks.
