Ubuntu build error for both /examples/java-matter-controller and /examples/kotlin-matter-controller

[kencottrell]

Build issue(s)

1. Do these run on Ubuntu OS? I can't tell from README.MD files for java-matter-controller and kotlin-matter-controller whether or not these only run on Android? It appears that these should work on Ubuntu?
2. If Ubuntu should work, I get the same build error when executing this:
   ./scripts/build/build_examples.py --target linux-x64-java-matter-controller build

Platform

other

Anything else?
