在做ssm框架的分散式專案時，使用quartz2.2.1框架新增定時任務時，報java.lang.IncompatibleClassChangeError: Implementing class異常，

異常程式碼如下：

Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'rolePermissionServiceimpl': Injection of autowired dependencies failed; nested exception is java.lang.IncompatibleClassChangeError: Implementing class

網上查找了很多資料，基本全部都是說jar包衝突問題，也就是說在新增quartz的依賴時，引入了低版本的jar包，也是我依次檢查了我的專案依賴jar以及maven本地倉庫中下載的依賴，剛開始在本地倉庫中刪除多餘版本之後，居然不可思議的啟動成功了，

但是幾天之後，重新啟動，又報了同樣的錯誤，這次刪除本地倉庫的方法顯然不奏效了，

這次在專案的編譯目錄中發現引入的jar依賴中版本有多個，於是想著排除低版本的依賴，嘗試無果之後，

繼續在網上查詢答案，無意間看到，pom檔案中maven座標的順序也有可能導致jar包衝突，

於是，在原專案的基礎上，只是改變了pom檔案中quartz依賴的位置，將其放置到pom檔案<dependency>標籤的頂部，重啟專案，問題解決

pom檔案如下：

 <dependencies>
        <dependency>
            <groupId>com.mn</groupId>
            <artifactId>mn-service</artifactId>
