So I am trying to replicate the textmining usecase of biograkn in the biograkn repo. I am trying to migrate the data in schema, for which i was supposed to do bazel build. so i ran the following command:
bazel build //migrator:migrator-bin
inside the textmining folder of biograkn. Now, the build fails and I am getting error:
Here is the traceback

I suspect its some antlr4 package issue on maven servers. How to resolve it, if there are any good workarounds?
Yes it looks like the link being depended upon is dead. You are trying to manually migrate the data yourself. To use BioGrakn in the most basic case, you can just download a pre-loaded set of data by following the link in the README/releases page.
If you want to customise things or use it as a basis for your own work, and you want to use Bazel, then the dependencies in the WORKSPACE file should point to more recent commits the relevant repos. In general this repo needs an update.
