我最近安装了ANT，这是我第一次使用它。问题是它一直说“安装了错误的Java编译器版本”，而我安装了JDK 1.8.0_51。有什么我做错了吗？我已将环境变量设置为指向jdk文件夹而不是jre one或bin目录。有解决方案吗这是错误的屏幕截图。

答案 0 :(得分：3)
在init目标中，当Java安装不是1.7时，您明确告诉Ant使构建失败。尝试在条件中包括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>
