在Eclipse上運行Google App Engine應用程序時出現HTTP錯誤500

Question

HTTP錯誤500

問題訪問/。 原因：

 java.lang.VerifyError: Expecting a stackmap frame at branch target 51 in method todo.Dao.add(Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;)V at offset 5 ...... 

上面提到的是我遇到的錯誤，我嘗試在“窗口->首選項->已安裝的JRE->並添加默認參數”中添加新的默認變量-XX：-UseSplitVerifier。 仍然出現相同的錯誤。 如果有人知道有關此問題的信息，請提供幫助

最好的問候MDG

我已經通過包含一個build.xml文件解決了這個問題

<?xml version="1.0" encoding="UTF-8"?>
