xxl-job运行

idea本地测试可以
生产环境不行
一直报类找不到

根本原因

java.lang.NoClassDefFoundError: groovy/lang/GroovyClassLoader
因为xxl-job本地测试运行要依赖服务端xxl-job-admin，这个需要下xxl-job的源码，而且源码里面是SNAPSHOT版本，里面的maven也写的是这个2.3.1-SNAPSHOT

但是客户端引入maven依赖的时候，要写xxl-job-core的坐标
正确写法

<!-- xxl-job-core -->
        <dependency>
            <groupId>com.xuxueli</groupId>
            <artifactId>xxl-job-core</artifactId>
            <version>2.3.1</version>
        </dependency>

错误写法

<!-- xxl-job-core -->
        <dependency>
            <groupId>com.xuxueli</groupId>
            <artifactId>xxl-job-core</artifactId>
            <version>2.3.1-SNAPSHOT</version>
        </dependency>

可见客户端里面写version字段一定要注意对应，不能写上SNAPSHOT
