What it does

Mvnf is an agent skill from eclipse-rdf4j/rdf4j. Run Maven tests in this repo with a consistent workflow (module test-artifact cleanup, root -Pquick install to refresh .m2repo, then module verify or a single test class/method). Use when asked to run tests/verify in the rdf4j multi-module build or when the user says mvnf.

Its SKILL.md is about 970 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including scripts (for example `scripts/mvnf.py`).

It sits in Testing & QA. It works with Python. The repository describes itself as: Eclipse RDF4J: scalable RDF for Java. The licence is BSD-3-Clause.

When your agent uses it

  • Asked to run tests/verify in the rdf4j multi-module build
  • The user says mvnf

Example prompts

  • “/mvnf”

Requirements

  • Python 3

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. Deletes stale target/surefire* and target/failsafe* artifacts for the selected module.
  2. mvn -B -ntp -Dmaven.compiler.showWarnings=false -T 1C -o -Dmaven.repo.local=.m2_repo -Pquick install
  3. mvn -o -Dmaven.repo.local=.m2_repo -pl verify (optionally with -DskipITs -Dtest=... for unit tests or -PskipUnitTests -Dit.test=... for…

What it can do on your machine

Read from SKILL.md and the folder at commit fdbf6e5. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 1 file in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • python3
    • mvn

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Mvnf loads about 971 tokens when it runs. Until then it costs about 70 tokens; SKILL.md has 369 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~70
When it runs · the whole SKILL.md, loaded when a task matches
~971

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

description
Run Maven tests in this repo with a consistent workflow (module test-artifact cleanup, root -Pquick install to refresh .m2_repo, then module verify or a single test class/method). Use when asked to run tests/verify in the rdf4j multi-module build or when the user says mvnf.

mvnf

Run Maven tests with repeatable commands and useful failure pointers.

Quick start

  • Run a module's full test suite:
    • python3 .codex/skills/mvnf/scripts/mvnf.py core/sail/shacl
  • Run a unit test class or method (module auto-detected):
    • python3 .codex/skills/mvnf/scripts/mvnf.py ShaclSailTest
    • python3 .codex/skills/mvnf/scripts/mvnf.py ShaclSailTest#testSomething
  • Run an integration test (Failsafe):
    • python3 .codex/skills/mvnf/scripts/mvnf.py --it ShaclSailIT#testSomething

What it does

  1. Deletes stale target/surefire* and target/failsafe* artifacts for the selected module.
  2. mvn -B -ntp -Dmaven.compiler.showWarnings=false -T 1C -o -Dmaven.repo.local=.m2_repo -Pquick install
  3. mvn -o -Dmaven.repo.local=.m2_repo -pl <module> verify (optionally with -DskipITs -Dtest=... for unit tests or -PskipUnitTests -Dit.test=... for Failsafe ITs)

Root install output is stored in maven-build.log. On success, mvnf prints one root-install summary line with BUILD SUCCESS and the log path. Verify logs use logs/mvnf/*-verify.log when retained or when tests fail. By default, successful Maven phases do not print their output tail; mvnf prints compact Surefire/Failsafe report totals and report paths instead. Failed phases still print the retained Maven tail plus compact report failure details.

For manual root clean installs, keep full output in maven-build.log and print only errors plus the reactor summary:

bash
mvn -B -ntp \
  -Dmaven.compiler.showWarnings=false \
  -T 1C -o -Dmaven.repo.local=.m2_repo -Pquick clean install 2>&1 \
  | tee maven-build.log \
  | awk '
     /\[WARNING\]/ { next }
      /\[ERROR\]/ { print; next }

      /Reactor Summary/ { summary=1 }
      summary { print }
    '

For install without clean, replace clean install with install. For a module install, add -pl <module> -am before -Pquick. Keep the 2>&1 | tee maven-build.log | awk ... tail on every install variant.

If the test run fails, it prints the list of Surefire/Failsafe report files under the module's target/*-reports/ directories. For a handoff-ready block from retained reports, run python3 scripts/agent-evidence.py <module>/target/surefire-reports <module>/target/failsafe-reports.

Options

  • --module <path>: Force the module when the test class name exists in multiple modules.
  • --it: Treat the selector as an integration test and pass it via -Dit.test=....
  • --no-offline: Run Maven commands without -o (useful if offline resolution fails).
  • --stream: Stream verify output live for hang/no-progress debugging; install output is filtered to errors plus the reactor summary while the full install log is kept in maven-build.log.
  • --tail-on-success: Print Maven output tails on successful phases too (old verbose behavior).
  • --retain-logs: Keep verify logs on success.
  • -- <maven args>: Append extra Maven flags/profiles to the verify command while preserving selector behavior.

LMDB regression speedup note

For LMDB theme regression/snapshot tests, enable persistent prepared stores to skip repeated dataset rebuilds:

  • -Drdf4j.lmdb.themeRegression.persistentStore.enabled=true
  • Optional root override: -Drdf4j.lmdb.themeRegression.persistentStore.root=persistent-lmdb-theme-store

Pass extra Maven flags after --, for example:

  • python3 .codex/skills/mvnf/scripts/mvnf.py LmdbThemeQueryRegressionTest#socialMediaFiveCycleInterleavesValuesWithFollowsEdges --module core/sail/lmdb -- -Drdf4j.lmdb.themeRegression.persistentStore.enabled=true

What does Mvnf do?

Run Maven tests in this repo with a consistent workflow (module test-artifact cleanup, root -Pquick install to refresh .m2repo, then module verify or a single test class/method). Mvnf is an agent skill from eclipse-rdf4j/rdf4j.m2repo, then module verify or a single test class/method).

When should I use Mvnf?

Mvnf fits situations like: asked to run tests/verify in the rdf4j multi-module build; the user says mvnf.

How do I install Mvnf in Claude Code?

Run `npx skills add eclipse-rdf4j/rdf4j --skill mvnf -a claude-code`. Or copy the skill folder (.agent/skills/mvnf in eclipse-rdf4j/rdf4j) into .claude/skills/mvnf in your project. Claude Code loads it when a task matches its description.

How do I install Mvnf in Codex?

Run `npx skills add eclipse-rdf4j/rdf4j --skill mvnf -a codex`. Or copy the skill folder (.agent/skills/mvnf in eclipse-rdf4j/rdf4j) into .agents/skills/mvnf in your project. Codex loads it when a task matches its description.

Can I use Mvnf in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add eclipse-rdf4j/rdf4j --skill mvnf -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/mvnf, .gemini/skills/mvnf, .github/skills/mvnf and .opencode/skills/mvnf in your project.

What does Mvnf need to run?

Going by SKILL.md and its folder, Mvnf needs Python for the scripts in its folder and the command-line tools its instructions call (python3 and mvn). Our summary lists: Python 3.

Does Mvnf access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Mvnf safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.

What licence does Mvnf use?

Mvnf is published under the BSD-3-Clause licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Mvnf use?

About 971 tokens (SKILL.md is roughly 3.9k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
