I checked out r738 of trunk/springpython, changed directory to src, and tried to run jython build.py install (based on the README.TXT which indicates to do the same, but with setup.py, which isn't present).

The setup seemed to be running fine, then came to the following error:

running install
...
copying springpython\LICENSE.txt -> build\lib\springpython
running build_scripts
creating build\scripts-2.5
error: file 'plugins\coily' does not exist
Sure enough, the only file in plugins is coily-template. I copied plugins/coily-template to plugins/coily and now the setup completed successfully.

Was that the correct fix? If not, what do you recommend to install Spring Python under jython?
