Slither does not handle non-default Truffle build folders

	if not os.path.isdir(os.path.join(contract, 'build'))\
	or not os.path.isdir(os.path.join(contract, 'build', 'contracts')):
	logger.info(red('No truffle build directory found, did you run `truffle compile`?'))
	sys.exit(-1)

, it hardcodes the default directory for Truffle: build/contracts.

However, this location can actually be customized; see https://truffleframework.com/docs/truffle/reference/configuration#contracts_build_directory.

I may try to submit a PR if I can find time this week.

That's a good idea, thank you for reporting the limitation!

Hi @Pneumaticat , I added the option --truffle-build-directory to specify a custom build path.

You can also set the option directly in slither config file, if you don't want to specify the flag at every run. Example of config:

$ cat slither.config.json 
{
    "truffle_build_directory":"custom/build_dir"
}

Note that Slither could parse the information directly from truffle.js, but I used a solution that does not require JS parsing.

This feature will be present in the upcomig 0.6.2 release.
