从命令提示符运行JAR文件时为什么会出现异常？ [英] Why am I getting an exception when running a JAR file from the command prompt?

问题描述

您好我在eclipse上使用导出选项制作了一个可运行的JAR文件。但是，当我通过命令提示符运行该文件时，我得到以下内容

Hi I have made a runnable JAR file useing export option on eclipse. However, when I go to run the file via command prompt i get the following

Exception in thread "main" java.lang.NoSuchMethodError
    at org.eclipse.jdt.internal.jarinjarloader.RsrcURLConnection.getInputStream(RsrcURLConnection.java:43)
    at java.net.URL.openStream(Unknown Source)
    at sun.misc.URLClassPath$Loader.getResource(Unknown Source)
    at sun.misc.URLClassPath.getResource(Unknown Source)

    at java.lang.Class.forName(Unknown Source)
    at org.eclipse.jdt.internal.jarinjarloader.JarRsrcLoader.main(JarRsrcLoader.java:56)    

有没有人对我做错了什么有任何想法？对整个创建可运行文件等都很陌生。

Does any one have any ideas as to what im doing wrong? pretty new to the whole creating runnable files etc.

推荐答案

你的jar是用比你的计算机更新的java版本编译的运行它。

Your jar is compiled with a newer version of java than the computer you are running it on.
