在使用Java 1.8的Windows上运行ant时发生ClassLoader异常 [英] ClassLoader exception when running ant on windows with java 1.8

问题描述

在使用Java 1.8.60的Windows系统上运行ant时遇到了这个问题。运行Java 1.7.25时，此方法工作正常。甚至更有趣：在Mac上执行时，它运行正常吗？

I ran into this issue when running ant on a windows system with java 1.8.60. This was working fine when running java 1.7.25. Even more interesting : it runs fine when executed on a mac?

我有点迷失了，因为没有太多指向我指出此问题的原因。

I am kind of lost since there is not much pointing me towards a cause of this problem.

推荐答案

确定JVM已正确安装？
当通过存储库（CVS）安装JVM时，我们遇到了同样的问题，该存储库将一些文本文件从/转换为DOS / UNIX格式。

Sure the JVM was installed properly? We had the same problem when the JVM was installed via a repository (CVS) which converted some text-files from/to DOS/UNIX format.
