I see there is a good amount of failed tests in CI, was this occurring locally too?

I see there is a good amount of failed tests in CI, was this occurring locally too?

Tests were passing locally on my personal laptop where I submitted this. Let me investigate.

[dbwiddis]

Failures are caused by not finding the json files:

java.io.FileNotFoundException: Resource [mappings/global-context.json] not found in classpath

But they are present in src/main/resources

Possible classloader issue from the class loading the stream, will try to fix...

[dbwiddis]

Fixed. Was using relative classpath which worked with my other laptop config but apparently wasn't portable.

The backport to 2.x failed:

The process '/usr/bin/git' failed with exit code 128

To backport manually, run these commands in your terminal:

# Navigate to the root of your repository
cd $(git rev-parse --show-toplevel)
# Fetch latest updates from GitHub
git fetch
# Create a new working tree
git worktree add ../.worktrees/flow-framework/backport-2.x 2.x
# Navigate to the new working tree
pushd ../.worktrees/flow-framework/backport-2.x
# Create a new branch
git switch --create backport/backport-383-to-2.x
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 fea3e6e3711017b4b19fd61e4c2318fe51f7dd45
# Push it to GitHub
git push --set-upstream origin backport/backport-383-to-2.x
# Go back to the original working tree
popd
# Delete the working tree
git worktree remove ../.worktrees/flow-framework/backport-2.x

Then, create a pull request where the base branch is 2.x and the compare/head branch is backport/backport-383-to-2.x.
