where is ant installed on Mac OS X snow leopard by default?

I don't have ANT_HOME set, so i want to 开发者_如何学编程find where the home directory of ant is. I'm using the version of ant that was installed by default on my OSX install.

Follow these instructions to find the location of any package:

whereis ant (replace 'ant' with whatever you're looking for)

On my machine, this reports:

/usr/bin/ant

so, I do:

ls -l /usr/bin/ant

on my machine this reports:

lrwxr-xr-x  1 root  wheel  22 Nov 30 17:09 /usr/bin/ant -> /usr/share/ant/bin/ant

so, I do :

ls -l /usr/share/ant 

and get:

lrwxr-xr-x  1 root  wheel  14 Nov 30 17:09 /usr/share/ant -> java/ant-1.8.1

from this I can surmise that ant is installed at /usr/share/ant/java/ant-1.8.1

If you run ant -diagnostics, it should tell you where the ant.home is

$ant -diagnostics

ant.home: /opt/local/share/java/apache-ant 

I do not had ANT at all in whole system, but i use NetBeans 8.1 or 8.2.

Step 1: Install NetBeans 8.2

Step 2: Apply the ant from NetBeans 8.2 does the easy job too
