与针对同一问题的其他开放线程不同，在这种情况下，所有版本都是一致的，并且 ant 承认这一点.尽管如此，它还是给出了这个问题.有什么见解吗?

Unlike other open threads for the same issue, in this case all the versions are coherent and ant is acknowledging it. Still, it is giving this issue. Any insight?

推荐答案

知道了！！！
java 1.8.45 与 ant 1.9.1 不兼容.切换到 java 1.7.67(jdk 和 jre)，一切正常.

Got it!!!
java 1.8.45 is not compatible with ant 1.9.1. Switched to java 1.7.67 (both jdk and jre) and everything is working fine.
