为什么ANT告诉我，JAVA_HOME是错误的，当它是不是？ [英] Why does ANT tell me that JAVA_HOME is wrong when it is not?

问题描述

我得到的错误：

C：\\ dev的\\ WS \\ springapp \\的build.xml：81：无法找到javac编译器;
com.sun.tools.javac.Main不在类路径中。
也许JAVA_HOME不指向JDK。
这是当前设置为C：\\ Program Files文件\\的Java \\ JRE6

C:\dev\ws\springapp\build.xml:81: 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\Java\jre6"

但我清楚我的设置JAVA_HOME为C：\\ Program Files文件\\的Java \\ jdk1.6.0_14

But I have clearly set my JAVA_HOME to be C:\Program Files\Java\jdk1.6.0_14

在哪里ANT获得这个值？

Where is ANT getting this value?

推荐答案

当你说你有明确规定JAVA_HOME为C：\\ Program Files文件\\的Java \\ jdk1.6.0_14 - 这就是你看到你的时候运行命令行套？我相信蚂蚁将用于JAVA_HOME值想，如果没有设置一个在所有...它可能是你已经设置JAVAHOME代替JAVA_HOME？

When you say you have "clearly set" JAVA_HOME to "C:\Program Files\Java\jdk1.6.0_14" - is that what you see when you run "set" from the command line? I believe Ant will guess at a value for JAVA_HOME if one isn't set at all... is it possible that you've set JAVAHOME instead of JAVA_HOME?

如果它没有像这一点，我建议你修改 ant.bat 批处理文件（以及任何调用 - 我不记得是否是令人费解或不随便）打印出JAVA_HOME在开始和其他各种有趣的地方。

If it's nothing like that, I suggest you edit the ant.bat batch file (and whatever it calls - I can't remember whether it's convoluted or not offhand) to print out JAVA_HOME at the start and at various other interesting places.
