jdx services

$ jdx services --help
Usage: jdx services [<options>] [<pattern>]

  List META-INF/services SPI registrations across the workspace's binary roots. With no pattern, every registration is shown; with a pattern, match the service interface FQN or a provider class FQN (substring by default). --regex treats the pattern as a Java regex; --ignore-case folds substring matches. --in/--exclude filter by artifact label; --limit caps provider rows (default 50). Exits 1 when nothing matches.

Options:
  --regex                 Treat the pattern as a Java regex matched against each service/provider FQN.
  --ignore-case           Case-insensitive substring match (ignored under --regex; use (?i) there).
  --in=<text>             Only artifacts whose label matches this glob (jar file name, JDK module or class-dir name).
  --exclude=<text>        Skip artifacts whose label matches this glob.
  --limit=<int>           Maximum provider rows shown (default 50); the rest become a truncation footer.
  --jars=<text>           Binary roots: jar files, class directories or globs (repeatable). Merge in front of the selected workspace's roots.
  -w, --workspace=<text>  Use a named workspace (see jdx ws). Explicit --jars merge in front of it.
  --no-jdk                Do not include the running JDK's stdlib (included by default).
  --coord=<text>          Maven coordinate root group:artifact:version (repeatable). Resolved from ~/.gradle/caches and ~/.m2 first; with --fetch, downloaded from Maven repositories into <cache-dir>/m2 with checksum verification. Merges in front of the workspace.
  --repo=<text>           Maven repository base URL for --coord fetches (repeatable, e.g. --repo https://repo.example.com/maven2). Tried in flag order before Maven Central, which stays last as the fallback. Must be an http(s) URL.
  --fetch                 Allow downloading --coord artifacts (and their -sources.jar) from Maven repositories (Central by default, --repo to add mirrors). Without it, coordinates resolve from the local caches only.
  --json                  Emit machine-readable JSON instead of human-readable text (same information, D-007).
  --no-color              Disable ANSI colors even on a TTY (piped output is always plain).
  --no-daemon             Force in-process execution: do not forward this query to the background daemon even when its socket answers (PROPOSAL.md §14.1).
  -h, --help              Show this message and exit

Arguments:
  <pattern>  Optional substring (or --regex pattern) matched against service and provider FQNs. Omit to list every registration.
