maven使用版本：3.5.0
今天遇到了很奇葩的問題，在用eclipse maven進行打包的時候報如下錯誤：

看到這個錯誤，無法看到是什麼導致的，就按照最後兩行的提示，在命令里加入了參數 -X，結果看到如下錯誤：

看到ArrayIndexOutOfBoundsException這個錯誤原因，仍然不知道怎麼解決，各種搜索，仍沒解決方法
項目clean，maven clean ，電腦、eclipse都重啓也都不管用
最後嘗試升級maven，從maven網站下載了最新的3.6.1，問題解決！！！！！！
所以以後如果出現maven問題且無法解決的情況，建議升級下maven版本試試！！！！！！！
