Getting started

# Step 1: Clone repo
git clone https://github.com/twitter/bazel-multiversion
cd bazel-multiversion

# Step 2: Build and run code with different versions of Guava
cd multiversion-example/
bazel build tricky/...
bazel run tricky/user/src/main/scala/bincompat:NeedsGuava24
bazel run tricky/user/src/main/scala/bincompat:NeedsGuava29
cd ..

# (optional) Step 3: make changes to 3rdparty.yaml and regenerate 3rdparty/jvm_deps.bzl
# NOTE: This step can become a native-imagine binary with instant startup.
./sbt multiversion/run export
