Drools I'；我流口水有毛病

我正在处理eclipse上的Drools，代码工作正常，突然出现了这些错误。我试着重新安装drools插件，卸载Eclipse，更新JRE和JDK，但没有任何效果

请提供帮助

您正在使用较旧版本的Drools。也许您正在使用比Drools版本6更新的JVM版本编译Java模型类。我使用Java11和Drools 7.39.0.Final，它可以按预期工作

    <dependency>
        <groupId>org.drools</groupId>
        <artifactId>drools-core</artifactId>
        <version>7.39.0.Final</version>
    </dependency>

org.drools
流涎核
7.39.0.1决赛

添加所需的java和drl代码段。请添加相关代码。感谢您的帮助，我指定了另一个JRE，它成功了
