jdx tree

IDE equivalent: External library browser (artifacts)

Show the package forest of each matching artifact (jar file name or JDK module; default '*' — every artifact). --depth caps nesting (0 shows top segments only), --counts adds per-package subtree type counts. Exits 1 when no artifact matches.

Usage#

jdx tree [<options>] [<artifact>]

Example#

$ jdx tree 'gson*' --depth 3 --coord com.google.code.gson:gson:2.14.0
package tree for 'gson*'
gson-2.14.0.jar
  com
    com.google
      com.google.gson
        com.google.gson.annotations
        com.google.gson.internal
        com.google.gson.reflect
        com.google.gson.stream
warning MULTI_RELEASE_VARIANT: multi-release gson-2.14.0.jar serves version-specific variants for this JDK (21)

Real output — this example ran against the current jdx when the page was built.

Options#

Option	Description
`--depth=<int>`	Maximum package nesting shown (default 8; 0 shows top-level segments only).
`--counts`	Show per-package subtree type counts.
`--limit=<int>`	Maximum package nodes 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
`<artifact>`	Artifact glob: jar file name or JDK module (default '*' — every artifact).
