在Drools Workbench 6.0.1中更改规则时未更新Drools kie存储库

Question

在drools中有问题，即6.0.1，同时将drools工作台集成到应用程序中。

String url = "http://localhost:4040/kie-drools-wb-distribution-wars-6.0.1.Final-tomcat7.0/maven2/com/dcproject1/dcproject1/1.0/dcproject1-1.0.jar";

    ReleaseIdImpl releaseId = new ReleaseIdImpl("com.dcproject1", "dcproject1","LATEST");

    KieServices ks = KieServices.Factory.get();

    ks.getResources().newUrlResource(url);

    KieContainer kieContainer = ks.newKieContainer(releaseId);

    // check every 5 seconds if there is a new version at the URL
    KieScanner kieScanner = ks.newKieScanner(kieContainer);
    kieScanner.start(5000L);

当我通过Drools-6 workbench UI更新工作台上的规则时，它将引发异常。

13:43:16.853计时器-0 INFO o.d.c.k.b.impl.KieRepositoryImpl - KieModule被添加: org.drools.compiler.kie.builder.impl.KieContainerImpl.updateToVersion(KieContainerImpl.java:161) at org.kie.scanner.KieRepositoryScannerImpl线程“Tim-0”java.lang.NullPointerException中的ZipKieModule o.d.c.k.b.impl.KieRepositoryImpl异常.updateKieModule(KieRepositoryScannerImpl.java:214) at org.kie.scanner.KieRepositoryScannerImpl.scanNow(KieRepositoryScannerImpl.java:204) at org.kie.scanner.KieRepositoryScannerImpl$ScanTask.run(KieRepositoryScannerImpl.java:193) at java.util.TimerThread.mainLoop(Timer.java:555) at java.util.TimerThread.run(Timer.java:505)

在修改规则时，是否应该更改工作台中的版本.

然而，添加新规则或删除现有规则非常有效.

感谢您的努力.

最后，我找到了解决办法。在Drools6.0.1中，当您在默认包中创建规则时，它将创建NullPointerException，同时从droools工作台修改该规则。
