The way that cake and lein behave is generally this:
1) Search up the file tree starting from the directory in which cake
or lein is called until a project.clj file is encountered. Consider
this to be the project root.
2) Start a JVM in this directory with the classpath set to contain any
files in src or lib.
When you are starting a new library, place it under the src directory
of your project. Then give it a namespace name in the ns form that
corresponds to its position beneath src, using . as a directory
separator.
So if your project file tree looks like this:
|-- LICENSE
|-- build
|-- classes
|-- lib
| |-- byte-spec-0.2.0-20100821.141701-1.jar
| |-- clojure-1.2.0.jar
| |-- clojure-contrib-1.2.0.jar
| |-- deps.clj
| |-- java-osc-cvs-20100502.112537-4.jar
| |-- jna-3.2.4.jar
| |-- midi-clj-0.2.0-20100821.141701-1.jar
| |-- miglayout-3.7.3.1.jar
| |-- osc-clj-0.3.0-20101217.045604-1.jar
| |-- overtone-0.1.5.jar
| |-- scsynth-jna-0.1.2-20100502.112537-1.jar
| `-- vijual-0.2.1.jar
|-- pom.xml
|-- project.clj
|-- src
| `-- overtone_test
| `-- core.clj
`-- test
Then your core.clj file should begin with an ns form like this:
(ns overtone-test.core
(:use [overtone.live]
[overtone.inst.synth]))
At compile-time, the Clojure compiler will look for your libraries
beneath your classpath (as established by lein or cake in the way I
described above) with names like overtone/live.clj and overtone/inst/
synth.clj.
And that, as they say, is that.
