KieScanner不能在Drools中工作6.1

我們有一個使用Drools規則集的Java應用程序。我們正在使用Drools 6.1。KieScanner不能在Drools中工作6.1

該規則在工作臺存儲庫中可用。我們希望在使用Workbench更改規則集時查看結果中的更改。所以，在我們的java代碼中，我們添加了Kiescanner模塊，它定期檢查這臺機器，但是我們不能成功。

我們的Java代碼

package com.sample; 

import org.drools.compiler.kproject.ReleaseIdImpl; 
import org.kie.api.KieBase; 
import org.kie.api.KieServices; 
import org.kie.api.builder.KieScanner; 
import org.kie.api.runtime.KieContainer; 
import org.kie.api.runtime.KieSession; 

import com.drools.project1.inputs; 

/** 
* This is a sample class to launch a rule. 
*/ 
public class DroolsTest { 

public static final void main(String[] args) { 

    try { 
     KieServices ks = KieServices.Factory.get(); 

     ReleaseIdImpl releaseId = new ReleaseIdImpl("com.drools", 
       "project1", "LATEST"); 

     KieContainer kieContainer = ks.newKieContainer(releaseId); 

     KieScanner kieScanner = ks.newKieScanner(kieContainer); 
     kieScanner.start(1000L); 

     while (true) { 

      KieBase kBase = kieContainer.getKieBase(); 

      KieSession kSession = kBase.newKieSession(); 

      inputs types = new inputs(); 

      types.setNum1(50); 
      kSession.insert(types); 
      kSession.fireAllRules(); 
      kSession.destroy(); 

      Thread.sleep(1000); 
      System.out.println("getNum2 = " + types.getNum2()); 

     } 

    } catch (Throwable t) { 
     t.printStackTrace(); 

     System.err.println(t); 
     System.err.println("Cause = " + t.getCause()); 
    } 
} 
}

我們制定的pom.xml和settings.xml的文件，以下列方式。

在另一方面，如果我們刪除本地倉庫或最新版本的 「resolver-status.properties」 文件時，代碼運行時，新版本從遠程機器自動下載到本地。但是，如果我們在Workbench上創建新版本，程序不會檢測到它。

我們能否做出缺失的描述？

謝謝你的建議。

Dools 6.1是舊版本，它可能與kieScanner有一些問題。試試最新版本的6.5版本的drools，看看是否遇到同樣的問題。
