我已经在我的Mac上下载了最后一个apache ant版本，但版本似乎是旧版本。 有什么想法吗？
myMac:~ mauri$ brew install ant

这里是相对的出口变量。

这里还有一个命令核心任务是什么意思？

我已经尝试从brew中再次卸载并安装ANT，但问题仍然是相同的

答案 0 :(得分：0)
我在重新审视帖子后意识到，您尝试安装ant，它已下载ant 1.9.7版本，并且提取似乎是/usr/local/Cellar/ant/1.9.7。
或者您可以使用下载的目录/Users/mauri/Downloads/apache-ant-1.9.6
因此，您需要做的就是将环境变量设置为正确的安装路径。
在终端上运行以下命令。
export ANT_HOME=/Users/mauri/Downloads/apache-ant-1.9.6
export CLASSPATH=$ANT_HOME/lib:$CLASSPATH
export PATH=$ANT_HOME/bin:$PATH
现在ant -v应该给出正确的结果。
请注意，上述更改仅适用于命令会话。如果您想永久应用它，请在~/.bash_profile文件中更新相同内容。
<强>更新
如果继续存在（即，指的是较旧版本的ant），则可以使用旧版本的软链接。尝试删除它。

我仍在尝试这背后的原因，但是Ant包装器脚本从/ etc中获取一些文件（如果存在），因此无论如何全局安装都可能泄漏到您的设置中。我猜关键是
core tasks : 1.8.2 in
file：/Library/Java/Extensions/selenium-html-runner-3.0.1.jar“ - 无论有什么 把Selenium放在那里，它优先。 我要感谢来自Apache ANT的Stefan Bodewig的这一伟大见解
