Question

运行drools-core 6.5.0.Final时出现错误，在mule中使用简单的弹簧配置。我使用的是spring 4.3.5.Final和JDK 1.8。我收到了一个错误 org.mule.module.launcher.DeploymentInitException：NoSuchFieldError：COMPILER_OPT_ALLOW_RESOLVE_INNERCLASSES_WITH_DOTNOTATION 在org.mule.module.launcher.application.DefaultMuleApplication.init（DefaultMuleApplication.java:205。初始化和验证KieContainer时失败。请注意我解压缩了存档，存档中没有冲突的jar。我只找到了2 drools特定的jar，drools-core和drools-decisiontables，版本6.5.0.Final。此外，没有重复的jar用于剩余的依赖项.pom只有所有spring框架4.3.5.RELEASE和Hibernate 4.3。< / p>

  kieContainer = KieServices.Factory.get().getKieClasspathContainer();

  LOG.info(kieContainer.verify().getMessages().toString());

我正在处理Excel电子表格决策表。

我搜索了一个原因，但没有找到答案。问题似乎与mvel库有关，但我不知道可能触发它的是什么。请帮忙！

我可以从堆栈跟踪中看到问题出现在我实现的spring方法中它在LOG.info下面失败了

     @Override
 public void afterPropertiesSet() throws Exception {
    kieContainer = ...;

        LOG.info(kieContainer.verify().getMessages().toString());
    try {


                  this.builder=factory.newDocumentBuilder();

             } catch (ParserConfigurationException e) {

问题在于类加载器。我做了以下解决问题：

 KieServices ks = KieServices.Factory.get();
        kieContainer = ks.newKieClasspathContainer(getClass    ().getClassLoader());
