I posted about this a day or so before the old group was closed, so it kinda drowned in all the other messages, I guess. I realize that the Homebrew package is maintained by some other people, but at the moment I am not sure where to post it, so here goes... When installing the ES package via Homebrew on Mac OS X I get the following warning: Warning: JARs were installed to "lib". Installing JARs to "lib" can cause conflicts between packages. For Java software, it is typically better for the formula to install to "libexec" and then symlink or wrap binaries into "bin". See "activemq", "jruby", etc. for examples. It's been like that for the last couple of months. ---

Pawel, What problem does this cause exactly? This is a pretty standard homebrew warning for Java packages, owing to Java assumptions Homebrew can't really isolate the environment, so the warning just says that. - Lee ---

It doesn't seem to cause any problems. The warning says it _may_ cause problems. I'm no Java developer and wouldn't know, I just saw a warning message and wanted to share it. ---

Strange, I thought that we fixed it at one point in the formula. Anyone up to looking at the suggested reference formulas and see if we can copy over what they do to be a better brew citizen? 2011/9/23 Paweł Krakowiak [pawel.krakowiak@gmail.com](mailto:pawel.krakowiak@gmail.com) > It doesn't seem to cause any problems.

I remember that from the time I got involved with the formula, it already spilled the warnings. I can't see any fixes when I quickly check out the diffs of ([Commits · Homebrew/legacy-homebrew · GitHub](https://github.com/mxcl/homebrew/commits/) master/Library/Formula/elasticsearch.rb)... I remember checking out AMQP formula to get a sense what should be done, but it was somehow unclear. Will check it out again. Seems like ActiveMQ is doing: libexec.install Dir['\*'] and we're doing: prefix.install Dir['\*'] Karel.
