Public bug reported:
Use-case: You have a "normal" Charm and you start porting it to
composer. You copy the charm from /trusty/mycharm to /layers/mycharm.
You start splitting the charm in layers and run `charm generate mycharm`
Expected result: You get an error explaining that the Charm
/trusty/mycharm already exists, and would be overwritten by `charm
generate`
Result you get: The following error message:
composer: Added unexpected file, should be in a base layer:
juju-client/config.yaml
Traceback (most recent call last):
File "/tmp/charm-tools/bin/charm-generate", line 9, in <module>
load_entry_point('charm-tools==1.7.1', 'console_scripts',
'charm-generate')()
File
"/tmp/charm-tools/local/lib/python2.7/site-packages/charmtools/compose/__init__.py",
line 468, in main
composer()
File

line 392, in __call__
self.validate()
File

line 384, in validate
"Unable to continue due to unexpected modifications (try --force)")
ValueError: Unable to continue due to unexpected modifications (try --force)
I think my use-case will happen a lot with people just starting with charms
layers. It would be great if the error message could be a little more
explanatory, and not give a python traceback...
