Hashes are required, even if setting is disabled about driver-binary-downloader-maven-plugin HOT 1 OPEN

Originally the plugin didn't work unless the hash was valid. The checkFileHashes option was added when some people requested a way to download files without checking the hash.

The plugin is designed to use hashes because this is how it checks that the file it has downloaded is correct. As a result the RepositoryMap.xml has an XSD that requires the hash field to be filled in.

To get the hash of a file you can do the following on the command line in OSX/Linux:

openssl sha1 <FileYouWantAHashFor>
openssl md5 <FileYouWantAHashFor>

For windows have a look at:

It looks like the chromedriver team no longer supply MD5 or SHA1 hashes of their files so that you can check that your download is not corrupt and is the expected file, this is disappointing.
