[英]drools plugin in Eclipse Sample.drl shows errors
I am new with Drools. 我是Drools的新人。 I use drools plugin (6.4.0.Final) in Eclipse Neon.
我在Eclipse Neon中使用drools插件(6.4.0.Final)。 I followed the wizard to create a drools project with some example files.
我按照向导创建了一个包含一些示例文件的drools项目。 After the steps were done, Eclipse highlighted errors at the two rules in the Sample.drl file.
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。 Here is one of the errors:
这是一个错误:

It seems like an library path issue. 这似乎是一个库路径问题。 Any helps are appreciated.
任何帮助表示赞赏。
Thank you very much! 非常感谢你!
This is a bug in either Neon or drools plugin, it's fixed in drools plugin (6.5.0.Final) based on this site: jboss-issue-description 这是Neon或drools插件中的一个错误,它基于此站点在drools插件(6.5.0.Final)中修复: jboss-issue-description
But since I don't find 6.5.0.Final version released, you can fix this by degrade eclipse to Mars 但由于我没有发现6.5.0.Final版本发布,你可以通过降低eclipse到火星来解决这个问题
