Running Maven Command From Java Program (From Eclipse) Mac OS

Question

I want to run Maven command from Java in Mac but I am getting the following error:

Exception in thread "main" java.io.IOException: Cannot run program "mvn": error=2, No such file or directory

My code looks like this:

p = Runtime.getRuntime().exec("mvn -version");

If I run the following command, it works fine. The only issue is related to Maven:

p = Runtime.getRuntime().exec("ls -ltr");

Answer 1

Does mvn -version works within the terminal window in eclipse? i had an issue running mvn command on eclipse terminal while it was working in OS terminal. I found these steps that fixed my issue:

1. add the "mvn_installation_location"/bin to /etc/paths file as root user.
2. right click eclipse and "show contents" then run eclipse from /Contents/MacOS/eclipse.
