今天新引入了一個二方庫，引入後發現程式無法啟動，有衝突和迴圈引用的問題。報錯資訊如下：

 Caused by: java.lang.IllegalStateException: Unable to complete the scan for annotations for web application [] due to a StackOverflowError. Possible root causes include a too low setting for -Xss and illegal cyclic inheritance dependencies. The class hierarchy being processed was [org.eclipse.jdt.core.CompletionContext->org.eclipse.jdt.internal.codeassist.InternalCompletionContext->org.eclipse.jdt.core.CompletionContext]

commond + o 全域性搜尋引用org.eclipse.jdt.core.CompletionContext的檔案， 

找到相關的jar包然後寫exlusion排除一下就可以了
