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

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
