How to detect and uninstall apache ant ?

Hello,
At my linux server I think there are 2 duplicate Apache Ant Installation
1) opt/ant
2) usr/local/ant

And whenever I tires to build ant using command 1)cd opt/ant 2) ant or 1)cd usr/local/ant 2) ant it shows error message "ant build failed"

Does it show above error due to duplicate installation?

1) Can I delete both ANT folders with rm -rf ant and install apache ant again? 2) Will deletion cause any harm?

Thanking You

Regards
ninad

It does not matter if you are under /opt/ant or /usr/local/ant, if you just run "ant" I'm pretty sure it's taking the one from your $PATH or $ANT_HOME.

It'd be different if you run /opt/ant OR /usr/local/ant.

It's unlikely.

Hello,
Thanks for your reply. I managed to run install latest version(1.8.1) of ant successfully.
I used following commands at my shell in which I logined with username root which is supreme userand export ANT_HOME=/opt/ant & export PATH=$PATH:/opt/ant/bin commands at my shell, after that ANT starts running and I tested it with ant -version command.
but after I logged out of shell and again logged in to find out ANT is not running again and path ANT_HOME and other PATH which I set before is empty. I wonder why it not saving changes? at ANT_HOME and PATH.

Really strange.

Regards
ninad

Environment variables don't work that way, they're neither system-wide nor persistent. Child processes inherit copies from parents and that's it. You need to modify a login script/profile/etc to set them correctly in the first place on login.

Hello,
I edited root/.bash_profile file for
ANT_HOME=/opt/ant
PATH=$PATH:$HOME/bin:/opt/ant/bin


ANT is working now.

However I still have problem with building ANT for my RED5 service
