使用Cygwin - Error的Maven: JAVA_HOME没有正确定义

I'm trying to run Maven on cygwin. I've added maven to the path and my Java home looks like this:

我想在cygwin上运行Maven。我在路径中添加了maven，我的Java主页看起来是这样的:

$ echo $JAVA_HOME 
/cygdrive/c/Program Files/Java/jdk1.6.0

Yet when I try to run mvn --version, I get this:

但是当我尝试运行mvn版本时，我得到了:

Error: JAVA_HOME is not defined correctly.
  We cannot execute /cygdrive/c/Program Files/Java/jdk1.7.0_01/bin/java

Any idea why it's not working? Java -version works fine, so it's not a problem with java. I've also tried jdk1.6.0 instead.

你知道它为什么不工作吗?Java版本工作得很好，所以这不是Java的问题。我还尝试了jdk1.6.0。

Running which java gives,

运行java提供了,

$ which java
/cygdrive/c/windows/system32/java

and java -version gives,

和java - version,

$ java -version
java version "1.7.0_01"
Java(TM) SE Runtime Environment (build 1.7.0_01-b08)
Java HotSpot(TM) Client VM (build 21.1-b02, mixed mode, sharing)

I had the same problem and solved it like this: If I run mvn.bat instead of mvn, I did not have this problem.

我遇到了同样的问题，并像这样解决了:如果我运行mvn。而不是mvn，我没有这个问题。

So, since Cygwin will run the mvn file, I replaced this mvn file with a softlink (ln -s mvn.bat mvn) to the bat file. This way, running mvn will silently run the mvn.bat which handles these problems gracefully.

因此，由于Cygwin将运行mvn文件，所以我用一个softlink (ln -s mvn)替换了这个mvn文件。bat mvn)到bat文件。这样，运行mvn将静默运行mvn。bat，优雅地处理这些问题。

Anyone Using Cygwin and Maven, here's exactly what you need...

任何使用Cygwin和Maven的人，这里正是您需要的……

In your Cygwin bash prompt:

在您的Cygwin bash提示符:

$ vim ~/.bashrc or $ nano ~/.bashrc (Which ever you fancy...)

vim ~ /美元。bashrc或$ nano ~/。bashrc(无论你怎么想…)

Append the following:

添加如下:

alias mvn=mvn.bat

别名mvn = mvn.bat

Save & Exit. Then run:

保存和退出。然后运行:

$ source ~/.bashrc

$ ~ / . bashrc来源

Now you should be able to use the 'mvn' command as you do in cmd prompt.

现在您应该可以像在cmd提示符中那样使用“mvn”命令了。

cygwin uses a dos console to execute maven builds (mvn.bat).

cygwin使用dos控制台执行maven构建。

I was facing the same problem while running gradle from cygwin tool.

在cygwin工具上运行gradle时，我遇到了同样的问题。

I used to set the java home including the bin folder

我曾经设置java home，包括bin文件夹

C:\Program Files\Java\jdk1.7.0_67\bin

But later i realized that some application do not recognize if u include bin folder, so i changed the class path to C:\Program Files\Java\jdk1.7.0_67 and it started working.

但后来我意识到,一些应用程序不承认如果你包括bin文件夹,所以我改变了类路径C:\Program Files\Java\ jdk1.7.0_67开始工作。
