KieScanner不在Drools 6.1工作

我们有一个使用Drools规则集的Java应用程序。我们正在使用Drools 6.1。

规则可在工作台存储库中找到。我们希望在使用Workbench更改规则集时看到结果中的更改。所以，在我们的java代码中，我们添加了Kiescanner模块，它定期检查这台机器，但是我们无法成功。

我们的Java代码

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());
    }
}
}

我们以下列方式创建了pom.xml和settings.xml文件。

另一方面，如果我们在代码运行时删除本地存储库中的最新版本或“resolver-status.properties”文件，新版本将自动从远程计算机下载到本地。但是，如果我们在Workbench上创建新版本，程序就不会检测到它。

我们可能缺少描述吗？

感谢您的建议。

Dools 6.1是旧版本，可能与kieScanner有一些问题。尝试6.5的最新版本的drools，看看你是否遇到同样的问题。
