maven_jar migration tool

maven_jar will be removed from Bazel 2.0 onwards. See this issue for more information.

This tool helps to automatically migrate your project from maven_jar to maven_install provided by rules_jvm_external.

These PRs were generated using this tool:

• https://github.com/google/copybara/pull/96
• https://github.com/kythe/kythe/pull/4180
• https://github.com/bazelbuild/rules_k8s/pull/463

Prerequisites

• Buildozer. Ensure that the buildozer is available in your PATH.

Usage

First, add the latest version of rules_jvm_external to your WORKSPACE by following the instructions on the releases page.

Then, add the following to your WORKSPACE to load the migrator's dependencies:

load("@rules_jvm_external//:defs.bzl", "maven_install")
load("@rules_jvm_external//migration:maven_jar_migrator_deps.bzl", "maven_jar_migrator_repositories")
maven_jar_migrator_repositories()

Next, run this command in root of project workspace to generate the maven_install WORKSPACE snippet:

$ bazel run @rules_jvm_external//migration:maven_jar

This command will also run the buildozer commands to migrate your project to use the new maven_install labels.

If the snippet looks good, concatenate it to the end of your WORKSPACE file:

$ bazel run @rules_jvm_external//migration:maven_jar >> WORKSPACE

Finally, if the build continues to succeed, you can remove maven_jar_migrator_repositories from your WORKSPACE file.
