JBPM项目永远不会完成构建

Question

我有一个依赖于WorkItemHandlers的JBPM应用程序。直到昨天，它都是在几秒钟内完成的。现在它需要20分钟来构建。从昨天开始，我在我的WIH和工作流程中所做的更改似乎微不足道--最有可能的罪魁祸首是我在WIH中添加了对kie-server-client的依赖。该项目没有规则--除了可能的网关条件--但日志错误暗示Business Central认为该项目有规则。

你认为从日志中给出的补救措施是什么？

15:03:38,138 WARN  [org.drools.compiler.kie.builder.impl.KieProject] (default task-9) No files found for KieBase KiePMML-Cluster-Rules

这就是新的依赖关系：

    <dependency>
      <groupId>org.kie.server</groupId>
      <artifactId>kie-server-client</artifactId>
       <exclusions>
            <exclusion>

            </exclusion>
            <exclusion>

                <artifactId>drools-core</artifactId>
            </exclusion>
       </exclusions>
      <!--version>${version.org.kie}</version-->
    </dependency>

如果我停止构建，我会看到这些有趣的日志片段：

Answer 1

在Business Central中，我允许我的WorkItemHandler jar可见，以便可以使用它定义的类。这显然在PAM/JBPM中触发了一个bug，它会在磁盘上搜索规则文件-尽管应用程序中没有规则。我删除了对新类的引用，并关闭了对依赖JAR的可见性，问题就消失了。
