ANT一直说“错误的JAVA版本”

Question

我最近安装了ANT，这是我第一次使用它。 问题是当我安装了JDK 1.8.0_51时，它总是说“安装了错误的Java编译器版本”。 我做错了什么吗？ 我将环境变量设置为指向jdk文件夹，而不是jre one或bin目录。 有什么办法吗？ 这是错误的屏幕截图。

在init目标中，您要明确告诉Ant在Java安装不是1.7的情况下使构建失败。 尝试在以下情况下包括1.8：

<target name="init">
   <echo message="Java Version: ${java.version}"/>
   <echo message="Java home: ${java.home}"/>
   <fail message="Unsupported Java version: ${java.version}. Make sure that the version of the Java compiler is 1.7 (7.0) or greater.">
     <condition>
      <not>
         <or>
           <contains string="${java.version}" substring="1.7" casesensitive="false"/>
           <contains string="${java.version}" substring="1.8" casesensitive="false"/>
         </or>
      </not>
     </condition>
   </fail>
</target>
