Question

我想将drools workbench 6.5.0.Final与我的应用程序集成。代码如下：

 private static void test() throws InterruptedException {
        KieServices kServices = KieServices.Factory.get();
        ReleaseId releaseId = kServices.newReleaseId("com.risk", "core-engine-test", "1.0.0-SNAPSHOT");
        kContainer = kServices.newKieContainer(releaseId);

        KieScanner kScanner = kServices.newKieScanner(kContainer);
        kScanner.start(10000L);

        Person p = new Person("郭芙蓉", 8);
        System.out.println("orig p1 : " + p);
        while (true) {
           Thread.sleep(5000);
           KieSession ksession = kContainer.newKieSession("testSession");
                ksession.insert(p);
                ksession.fireAllRules();
                System.out.println("after p1 : " + p);
                ksession.dispose();
            }
  }

以下是我自己的应用程序使用的settings.xml。

  <mirrors>
        <mirror>
            <id>nexus</id>
            <url>http://10.240.132.81:8081/nexus/content/groups/public/</url>
            <name>nexus</name>
            <mirrorOf>central</mirrorOf>
        </mirror>
    </mirrors>

我安装并将kjar部署到我的nexus存储库中。当我第一次启动应用程序时，它会编写一个名为“resolver-status.properties”的跟踪文件，并且此文件会记录一些timstamp，因此本地服务器不会不再在nexus-server中获取更新的jar。我得到了这样的日志：

任何人都可以帮我搞清楚吗？谢谢！

目前LATEST工作得很好，前提是你总是使用固定版本。相反，如果你尝试将它与SNAPSHOTs一起使用，它确实被破坏了，它是不可能的。根据邮件链[1]，答案就是那个＆＃34; LATEST被设计打破了＃34;。 [1]然而，在Maven文档中也说明了＆＃34;为了可重现的构建，Maven 3.x不再支持使用这些metaversions＆＃34;。 [2]

Drools KieScanner无法自动获取SNAPSHOT版本！
