我正在收到以下错误信息:
错误内容如下:
BUILD FAILED C:\Users\myname\Documents\CMSC\Proj1\build.xml:22: Unable to find a javac compiler; com.sun.tools.javac.Main is not on the classpath. Perhaps JAVA_HOME does not point to the JDK. It is currently set to "C:\Program Files (x86)\Java\jre7" Total time: 1 second
我的 build.xml 文件包含以下代码:
<project name="Project1" default="compile" basedir=".">
<description>
Build file for Project1
</description>
<!-- global properties for this build file -->
<property name="source.dir" location="src"/>
<property name="build.dir" location="bin"/>
<property name="doc.dir" location="doc"/>
<property name="main.class" value="proj1.Project1"/>

我在这里做错了什么?看起来它试图在我的 src 文件夹中查找 javac 文件,但我不知道该如何修复。
