Fetch Maven artifacts in 0.2.0 via secure URLs

[vmax]

Recently Maven Central started enforcing HTTPS when downloading artifacts (ref)

We've fixed the URLs as per their suggestion in our fork: https://github.com/graknlabs/rules_antlr/tree/0.2.1

@marcohu would it be possible for you to release 0.2.1 which contains updated URLs? Unfortunately, upgrading to 0.4.0 for us is not an option because we're using Java 8 and it contains code that is only compatible with Java 11 (such as String::isBlank)

The real issue is the unwanted Java 11 dependency. It has been fixed in the dev branch. I will cut a new release when support for 4.8 and 4.7.3 has been added, but I won't touch the old code.

Thanks for bringing the issue to my attention.
