Eclipse 啟動發生 Caused by: java.lang.ClassNotFoundException: javax.annotation.PreDestroy

因為開發環境的 SpringToolSuite4 要求更新 Java，更新到 Java 11 之後，反而 SpringToolSuite3 就打不開了，啟動就跳出下圖：

Eclipse 無法啟動

按照指示查看 log，看起來是跟 Java 9 引入的 module 功能相關，造成找不到這個 PreDestroy 這個類別。

解決方法：以下方法為 Eclipse / SpringToolSuite 通用，到 Eclipse / SpringToolSuite 資料夾下編輯 eclipse.ini 或 STS.ini，在 -vmargs 之前加上 -vm 參數指定啟動使用的 Java，下方範例我指定到我原本安裝的 Java 8 其 bin 資料夾下的 java 檔案。

另外要注意，-vm 是一列，指定路徑也是單獨一列，記得換行！
