我在OS X Mavericks上运行mvn时出现以下错误：无法运行程序“/ bin / sh”：error = 2，没有这样的文件或目录

Question

I am running OS X Mavericks on a MacBook Pro.

I have maven 3.0.5 installed.

When I run mvn, I am getting the following error message.

Error while executing process. Cannot run program "/bin/sh": error-2, No such file or directory

And before you ask:

PATH="/usr/local/apache-maven-3.0.5/bin:/Library/Java/JavaVirtualMachines/jdk1.7.0_79.jdk/Contents/Home/bin:/usr/local/bin:/bin:/usr/bin"

M2_HOME="/usr/local/apache-maven-3.0.5"

M2="/usr/local/apache-maven-3.0.5/bin"

MAVEN_OPTS="-Xms256m -Xmx768m -XX:MaxPermSize=512m"

I am also seeing the following near the beginning of the mvn output: [WARNING] Some problems were encountered while building the effective settings

[WARNING] Failed to use environment variables for interpolation: Cannot run program "env": error=0, spawn failed @

I had the same problem: exec() failed with ANY executable. Finally remembered that I was using a private jre. That jre was a copy of the original one, just with bin/java set as executable.

I made lib/jspawnhelper executable and it worked!

It seems your system is missing the "sh" shell to start interpreting the script.

I just looked up installed shells on Mac OSX and got this result:

/bin/zsh
/bin/ksh
/bin/tcsh
/bin/bash
/bin/sh

So when "/bin/sh" is missing, try "/bin/bash" for example.

Better:

1. Check if "/bin/sh" exist
2. If exist check if the user which runs the command can execute the shell

Because it can be possible that the shell binary exist but isn't executable for you. Then you have to make it executable for the user trying mvn.

Hope that helps ;)

If you are using eclipse , this is due to the java version. point java to your OS java instead of eclipse java. this will be solved
