本文解决了一个常见的Drools开发问题，即因缺少Eclipse JDT Core jar包导致的编译错误。通过添加正确的Maven依赖，项目能够成功编译并运行Drools规则。

Drools报错:The Eclipse JDT Core jar is not in the classpath

Caused by: java.lang.RuntimeException: The Eclipse JDT Core jar is not in the classpath

项目使用的是如下drools版本：

<properties>
    <drools.version>6.5.0.Final</drools.version>
    <fastjson.version>1.2.8</fastjson.version>
</properties>
<dependencies>

    </dependency>

解决办法：maven加入依赖

<!-- https://mvnrepository.com/artifact/org.eclipse.jdt/core -->
<dependency>
    <groupId>org.eclipse.jdt</groupId>
    <artifactId>core</artifactId>
    <version>3.3.0-v_771</version>
</dependency>
