Question

我是Drools的新人。我在Eclipse Neon中使用drools插件（6.4.0.Final）。我按照向导创建了一个包含一些示例文件的drools项目。完成这些步骤后，Eclipse突出显示了Sample.drl文件中两个规则的错误。以下是其中一个错误：

Multiple markers at this line
com.sample.DroolsTest.Message cannot be resolved to a type
org.drools.core.util.bitmask.AllSetBitMask cannot be resolved to a type
Only a type can be imported. com.sample.DroolsTest.Message resolves to a package

Message.GOODBYE cannot be resolved to a type
org.kie.api.runtime.rule.RuleContext cannot be resolved to a type
java.lang.Exception cannot be resolved to a type

当我运行DroolsTest.java时，我收到以下错误：

这似乎是一个库路径问题。任何帮助都表示赞赏。

非常感谢！

这是Neon或drools插件中的错误，它已根据此网站在drools插件（6.5.0.Final）中修复：jboss-issue-description

但由于我没有发现6.5.0.Final版本，你可以通过降低日食到火星来解决这个问题

Eclipse中的drools插件Sample.drl显示错误
