How can I get a list of build targets in Ant?

Question

My codebase has a long build.properties file written by someone else. I want to see the available built targets without having to search through the file manually.

Answer 1

The -p or -projecthelp option does exactly this, so you can do:

ant -p build.xml

You can make a target to invoke this like:

which you can then set as the default, so just typing ant will list the available targets.
