如何在不更改代碼的情況下從編譯的jar中檢索完整的異常消息？

Java應用程序終止，出現異常：如何在不更改代碼的情況下從編譯的jar中檢索完整的異常消息？

我現在NumberFormatException的應該包含「對於輸入字符串」文本。我能做些什麼來查看該異常的消息文本？

不從代碼，這是運行與bat文件這樣的編譯的Jar應用：

java -cp "%CP%" %JAVA_OPTS% liquibase.integration.commandline.Main %CMD_LINE_ARGS%

可能沒有留言供您查看。如果NumberFormatException有詳細消息，它將成爲堆棧跟蹤的一部分。 Here is the javadoc for NumberFormatException。你會注意到，不能保證例外會有詳細的信息。實際上，它有a no-argument constructor，它被記錄爲構造「沒有詳細消息的NumberFormatException」。

此外，here is the main constructor用於BigDecimal類的OpenJDK實現。如果你仔細觀察它，你會發現它在幾個地方拋出了沒有詳細信息的NumberFormatExceptions。
