项目依赖全量升级至较新稳定版本，如spring、Jackson、groovy等等；

doc/XXL-JOB官方文档.md

 - 37、任务执行日志、调度日志字段类型调整，改为text类型并取消字数限制；
 - 38、GLUE任务脚本字段类型调整，改为mediumtext类型，提高GLUE长度上限；
 - 39、任务监控线程Log输出优化，运行中任务的监控Log改为debug级别，减少非核心日志量；
+- 40、项目依赖全量升级至较新稳定版本，如spring、Jackson、groovy等等；
 
 ### TODO LIST
 - 1、任务权限管理：执行器为粒度分配权限，核心操作校验权限；
