The Java monorepo is now starting to use the versions.txt at the root for all submodules in the repository (single-component setup).

In https://github.com/googleapis/google-cloud-java/pull/8731/files, owlbot-java unexpectedly created "versions.txt" in the eventarc module and reset the version to 0.0.1-SNAPSHOT.

I need to find a way to adjust the single-component setup:

• When an existing module of the google-cloud-java monorepo is updated
• When a new module of google-cloud-java monorepo is created
• When an existing module of a split repo is updated
• When a new module of an existing split repo is created
• When a new split repo library is created (Maybe I don't need this)

How to confirm?

In one window, run:

~/synthtool$  docker build -f docker/owlbot/java/Dockerfile .

In another window, run:

cd google-cloud-java
gh pr checkout 8731
git reset --hard d9356a599b5a06689bf70c48f482b8ac28744a34

And then

git reset --hard d9356a599b5a06689bf70c48f482b8ac28744a34
docker run --rm -v $(pwd):/workspace XXXXXXX
chown -R suztomo .
git add -A
git commit -m 'chore: manual owlbot-java invocation'
