I built libraries for a while using Eclipse and the MacOS default system Java (Java 10) – but with a project configured as a Java 8 project. It would give a warning, but it always compiled fine.

To clean up the build process and remove the warning I finally added Java 8.0.192 to the Eclipse build path and used that for projects. That also worked fine, but with no warning.
