无法验证ANT 1.9.7设置

Question

我刚刚在一台运行Windows 10的新电脑上安装了Java+Ant，当测试"Java-version"返回预期结果时，尝试"Ant-version"返回几个错误消息：

C:>ant -version

这种情况发生在最新的1.9.7版本中，但我也尝试了1.9.6，并在这台电脑上获得了相同的结果。我已经配置了以下环境变量集：

ANT_HOME=C:PROGRA~2ApacheAnt-1.9.7
JAVA_HOME=C:PROGRA~1Javajdk1.8.0_73
PATH=%SystemRoot%;%SystemRoot%system32;%JAVA_HOME%bin;%ANT_HOME%bin;

在谷歌上搜索任何错误消息行都不会检索到任何有趣的内容。这也不是PATH问题，因为Ant确实返回了错误，我也尝试直接从"bin"文件夹调用该命令。。。

Answer 1

睡了一个好觉后，我想调查%PATHEXT%中定义的扩展执行顺序。

不知怎么的，安装程序一定已经从更改了它

PATHEXT=.COM;.EXE;.BAT;.CMD;

至

PATHEXT=.EXE;.CMD;.COM;.BAT;

重置%PATHEXT%的原始订单后，我的问题得到了解决。。。正确的顺序如下：

PATHEXT=.COM;.EXE;.BAT;.CMD;

bin文件夹中有两个"ant"可执行文件，一个是".bat"，一个".cmd"。键入

ant.bat -version

产生预期的输出。键入

ant.cmd -version

产生了我在问题中报告的错误。因此，通过在查看".cmd"之前处理".bat"来更改扩展执行顺序…

Answer 2

根据ANT文档，尝试以下

您可以打开一个新的shell并键入ant来检查基本安装。你应该得到这样的信息

Buildfile: build.xml does not exist!
Build failed

所以蚂蚁是有效的。之所以出现此消息，是因为您需要为项目编写一个单独的构建文件。

对于蚂蚁版本，你应该得到类似的输出

  Apache Ant(TM) version 1.9.2 compiled on July 8 2013

如果这不起作用，请确保环境变量设置正确。他们必须下定决心：

 required: %ANT_HOME%binant.bat
 optional: %JAVA_HOME%binjava.exe
 required: %PATH%=...maybe-other-entries...;%ANT_HOME%bin;...maybe-other-entries...
