I cant seem to build the plugin with lein. It gives the following error:

# lein uberjar
lein-javac: system java compiler not found; Be sure to use java from a JDK\nrather than a JRE by eit
her modifying PATH or setting JAVA_CMD.
Uberjar aborting because jar/compilation failed: Subprocess failed
#

Both on Windows and Linux, for me. I only have the JDK installeed.

This was because the JDK, on Windows, also installs the JRE. I uninstalled the JRE and this worked.
