今天负责交接xxl-job数据同步系统，首先当然是将项目跑起来啦

但是项目拉下来后，配置好，运行抛了个NoClassDefFoundError异常：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'xxlJobExecutor' defined in class path resource [org/springblade/job/executor/config/XxlJobConfig.class]: Invocation of init method failed; nested exception is java.lang.NoClassDefFoundError: groovy/lang/GroovyClassLoader

添加如下依赖，问题解决

<dependency>
    <groupId>org.codehaus.groovy</groupId>
    <artifactId>groovy-all</artifactId>
    <version>2.5.2</version>
    <type>pom</type>
