Within the parent project, child ones were already visually hidden in my case, but still found through search and Ctrl-click links.

I solved this by using Resource filters:

1. Right-click (parent) project > Properties > Resource > Resource Filters
2. Click Add Filter..., select Applies to -> Folders and enter one child project's folder name, click OK
3. Repeat 2. for all child project folders

By the end, you should have something like this:

curl -X POST -H 'Content-type: application/json' --data '{"text": "'"${message}"'"}'

@Deprecated public static Scheduler elastic()

Deprecated. use boundedElastic(), to be removed in 3.5.0

Scheduler that dynamically creates ExecutorService-based Workers and caches the thread pools, reusing them once the Workers have been shut down.

The maximum number of created thread pools is unbounded.

The default time-to-live for unused thread pools is 60 seconds, use the appropriate factory to set a different value.

This scheduler is not restartable.

Returns:default instance of a Scheduler that dynamically creates ExecutorService-based Workers and caches the threads, reusing them once the Workers have been shut down
