- Fixes the issue that sometimes occurred on CI where old `services` configuration was not cleaned and SPI definitions were leaking between PRs, causing random failures:
```
❌ should allow selecting table rows based on a boolean column
An unexpected panic was thrown: java.util.ServiceConfigurationError: org.enso.base.file_format.FileFormatSPI: Provider org.enso.database.EnsoConnectionSPI not found
```
- The issue is fixed by detecting unknown SPI classes before the build, and if such classes are detected, cleaning the config and forcing a rebuild of the given library to ensure consistency of the service config.

/** A helper task that ensures consistency of SPI services definitions.
|
|
*
|
|
* It should be attached as a dependency to `Compile / compile / compileInputs` of a given library.
|
|
*
|
|
* It detects any unknown classes in the `services` definitions and forces a recompilation if needed, to ensure the
|
|
* consistency of the definitions. Without this helper task, the incremental compiler did not detect removed service
|
|
* classes, thus after such a class was removed, it still stayed in the SPI configuration - crashing at runtime when
|
|
* the missing class was attempted to be instantiated. Only a `clean` allowed to regenerate the SPI configuration.
|
|
* This was causing issues on the CI when switching between PRs that have some new SPI configurations - they were
|
|
* leaking and crashing unrelated PRs.
|
|
*
|
|
* This task is created with the `std-*` Java helper libraries in mind and is aimed primarily at Java-only projects.
|
|
* Additional tweaks may be needed to get it working for mixed Java/Scala projects, if ever needed.
