# jdx services

IDE equivalent: META-INF/services SPI providers

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.

## Usage

```text
jdx services [<options>] [<pattern>]
```

## Example

```console
$ jdx services java.sql.Driver --coord org.postgresql:postgresql:42.7.4 --fetch --no-jdk
services matching 'java.sql.Driver'
postgresql-42.7.4.jar (1)
  service java.sql.Driver
    provider org.postgresql.Driver
```

## Options

| Option | Description |
|---|---|
| `--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

| Argument | Description |
|---|---|
| `<pattern>` | Optional substring (or --regex pattern) matched against service and provider FQNs. Omit to list every registration. |
