Unable to understand how to build for migrate.java to work

[adiv5]

Description

This is for the usecase textmining.I have loaded schema in keyspace, but then when i try to migrate data using migrate.java, I cant understand how to get it to work

i initially tried javac migrate.java but it failed because repo uses bazel for building.

hence i went to the textmining directory, and ran

bazel build //migrate/migrator-bin.jar

to which i am getting the following error:

build aborted: no such package '@antlr4_tool//jar'
