On FreeBSD drip does not work as a drop-in replacement for java.

Drip does not seem to pass parameters along to java correctly on FreeBSD

What version of bash is installed?

See following output:

[1222][jostein@invalid:~]$ bash --version
bash --version
GNU bash, version 4.2.37(0)-release (i386-portbld-freebsd7.4)

I've inspected the environment and it seems (which seems to match my memory) that FreeBSD does not ship with bash out of the box, and that this is built from source via the ports-system. /usr/bin/env bash, resolves to "bash", which only occurance is in /usr/local/bin/bash.

Looking into this one a little bit more myself, it seems like the issue is with the expr-binary, I find that what works on my Raspberry Pi running Raspbian (Debian-based Linux) does not work on FreeBSD.

Observe the following output on Raspbian:

jostein@raspberry:~$ expr "-cp" : '.*[.-]'
1
jostein@raspberry:~$ expr --version
expr (GNU coreutils) 8.13

And the following on FreeBSD:

[1300][jostein@invalid:~]$ expr "-cp" : '.*[.-]'
expr: illegal option -- c
usage: expr [-e] expression

"-cp" is taken as an option to expr. Doing the following to prevent this however, seems to trigger same behaviour as in GNU expr:

[1301][jostein@invalid:~]$ expr -- "-cp" : '.*[.-]'
1

Replacing all occurances of "expr" with "expr --" in the drip script seems to fix the error on FreeBSD:

[1302][jostein@invalid:~/.m2/repository/org/clojure/clojure/1.4.0]$ drip -cp clojure-1.4.0.jar clojure.main
Clojure 1.4.0
user=>

Same modified script tested on Raspberry Pi running Linux:

jostein@raspberry:~$ drip -cp clojure-1.4.0.jar clojure.main
Clojure 1.4.0
user=>

Seems like we have a simple fix :)

Thanks for tracking this down!
