export JAVA_HOME with spaces in Cygwin

问题

I'm trying to set my JAVA_HOME in Cygwin with this command:

export JAVA_HOME="/cygdrive/c/Program Files/Java/jdk1.7.0_10"

But when I do cd $JAVA_HOME, I'd get this error:

$ cd $JAVA_HOME
-bash: cd: /cygdrive/c/Program: No such file or directory

I tried quoting, and escaping the space (ie., \), but none worked. Any idea what else would?

Thanks,

I faced this problem too and I saw many posts but nothing really worked. There is a small trick that I did and things started working.

My JAVA_HOME was set to C:/Program Files/Java/jdk1.7.0_23. The problem was with Program Files directory and I was getting the same error.

In Windows there is a short name created for every directory with a space which is without a space. You can see it by running dir /X command on the command prompt. The Short name for Program Files was PROGRA~1.

In the Windows env variable through My Computer I changed the JAVA_HOME to C:/PROGR~1/Java/jdk1.7.0_23 and in hadoop-env.sh I changed JAVA_HOME to /cygdrv/c/PROGRA~1/Java/jdk1.7.0_23.

It worked fine.

You set JAVA_HOME correctly. Now let's cd correctly too.

cd "$JAVA_HOME"

To avoid using the tedious Windows environment variables, and also use the actual path string copied from Windows explorer, I suggest adding the following to your startup script:

             TMP=`cygpath -sw "C:\Program Files\Java\jdk1.8.0_31"`
export JAVA_HOME=`cygpath -u $TMP`

The first cygpath invocation obtains a short, windows path; the second converts it to unix format, which works fine in cygwin.

This will also now work fine:

$ cd $JAVA_HOME

Try to use short name to avoid a space in a path.

"C:\Program Files" should have short name C:\Progra~1 (you can verify it using DOS dir command or entering it into address bar in file explorer).

Set your JAVA_HOME this way:

export JAVA_HOME="/cygdrive/c/Progra~1/Java/jdk1.7.0_10"

Try using the DOS subst command to take the spaces of the JAVA_HOME path name. Assuming drive J; is not mounted or otherwise used.

In a DOS shell

subst j: "C:/Program Files/Java/jdk1.7.0_45"

J: is now an abbreviation for C:/Program Files/Java/jdk1.7.0_45

You can now cd to J:

now run Cygwin and

export JAVA_HOME="J:"

回答6:

I installed Java outside of "Program Files", specifically in c:\tools. Then you can use cygpath to convert the C:\tools\jdk1.8.0_144 to /cygdrive/c/tools/jdk1.8.0_144

on MSYS2 terminal

checke for previous claim: ls "/C/program files/" !works! -thats for long file names so, to the point:

export JAVA_HOME="/D/Devel/jdk-12.0.2"

And now maven works....

check:

user55@DESKTOP MSYS ~
# echo $JAVA_HOME
/D/Devel/jdk-12.0.2

You can give the normal C: directory path, and if surrounded by "" you don't need to escape the space in Program Files.

export JAVA_HOME="C:/Program Files/Java/jdk1.7.0_45"
