Command not found via ssh with single command, found after connecting to terminal [duplicate]

Answer 1

By default profiles aren't loaded when connecting via ssh. To enable this behaviour, set the following option in /etc/ssh/sshd_config:

PermitUserEnvironment yes

afterward restart ssh

/etc/init.d/ssh restart

Answer 2

Specify the absolute path to ant, if I recall correctly your profile doesn't get run when you run a remote ssh command.
