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

Question

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

Solution 1

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

Solution 2

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

$ant -diagnostics 

-------------------------------------------
ANT PROPERTIES

ant.version: Apache Ant(TM) version 1.9.2 compiled on July 8 2013
ant.java.version: 1.6
ant.core.lib: /opt/local/share/java/apache-ant/lib/ant.jar
ant.home: /opt/local/share/java/apache-ant

You can also do "which ant" instead of using "whereis..."

Correction: The path would be /usr/share/java/ant-1.8.1

This dies not help to find the location of ANT_HOME on every system. Using ant -diagnostics | grep ant.home is more precise.

I admit the question could be confusing. Not having ANT_HOME set as an exported environment variable on OSX seems to be totally common, at least on the 10 OSX servers I manage. Nevertheless ant -diagnostic tells you its default value of ant.home, even if the environment variable ANT_HOME is not set. If ant is not even on the PATH, which wouldn't allow for querying the diagnostics, and you're looking for the binary, you may even want to use find / -name "ant" -type f.

This produces an error: Error: Could not find or load main class org.apache.tools.ant.launch.Launcher

@IgorGanapolsky you probably need to add your JAVA_HOME in env variable
