Everything in CAP / Node.js

CAP Java is outside it: the plugin is written for CAP Node.js applications, and `cds add decisions` prints a message and writes nothing in a Java project. A decision needs an answer, so the service cannot be queued: a truthy `queued`, `outboxed` or `outbox` setting fails with `INVALID_CONFIG`, which rules out handing a call to the outbox. The package is not yet on npm, so it is installed from a GitHub release archive, and the subclass hooks, the HTTP mock server, the `cds add` facet and the provider test kit are marked experimental.
