# 151-java-performance-jmeter Sets up JMeter load testing in Java projects by creating a run-jmeter.sh script and standard test directories. - skill · `type=skill` · Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, OpenCode · 349 installs · ★ 456 - Author: Juan Antonio Breña Moral - License: Apache-2.0 · policy=mirror · the beginning of the file is at the end of this page - Source: https://github.com/jabrena/plinth/tree/HEAD/skills/151-java-performance-jmeter/SKILL.md - Updated: 2026-10-21 - HTML: https://affpapa.org/en/nevibecode/skills/151-java-performance-jmeter ## What it does The skill first checks `jmeter --version`. If JMeter is not on your `PATH`, the agent stops immediately. It then scaffolds `src/test/resources/jmeter/` for `load-test.jmx` and `target/` for output artifacts. Next, it copies `run-jmeter.sh` into the project root and runs `chmod +x run-jmeter.sh`. The template stays unmodified. The script accepts flags for threads (`-t`), loops (`-l`), ramp-up (`-r`), and GUI mode (`-g`). You can also override settings via `JMETER_THREADS`, `JMETER_LOOPS`, or `JMETER_RAMP_UP`. Without JMeter in your `PATH`, the workflow fails immediately. Install JMeter beforehand. ## Install ### Claude Code (native platform) 1. **Skills CLI (Vercel)** ```bash npx skills add jabrena/plinth --skill 151-java-performance-jmeter -a claude-code ``` 2. **Manually: put the files in place** - File: `~/.claude/skills/151-java-performance-jmeter/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/151-java-performance-jmeter/ ### Codex 1. **Skills CLI (Vercel)** ```bash npx skills add jabrena/plinth --skill 151-java-performance-jmeter -a codex ``` 2. **Manually: put the files in place** - File: `.agents/skills/151-java-performance-jmeter/SKILL.md` — For all projects use ~/.agents/skills/ ### Cursor 1. **Skills CLI (Vercel)** ```bash npx skills add jabrena/plinth --skill 151-java-performance-jmeter -a cursor ``` 2. **Manually: put the files in place** - File: `.cursor/skills/151-java-performance-jmeter/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/ ### GitHub Copilot 1. **GitHub CLI** ```bash gh skill install jabrena/plinth 151-java-performance-jmeter ``` 2. **Manually: put the files in place** - File: `.github/skills/151-java-performance-jmeter/SKILL.md` ### Gemini CLI 1. **Skills CLI (Vercel)** ```bash npx skills add jabrena/plinth --skill 151-java-performance-jmeter -a gemini-cli ``` 2. **Platform CLI** ```bash gemini skills install https://github.com/jabrena/plinth --path skills/151-java-performance-jmeter ``` ### Windsurf (Devin Desktop) **Manually: put the files in place** - File: `.devin/skills/151-java-performance-jmeter/SKILL.md` — The legacy .windsurf/skills/ path still works ### OpenCode **Skills CLI (Vercel)** ```bash npx skills add jabrena/plinth --skill 151-java-performance-jmeter -a opencode ``` ### Claude.ai **Claude.ai** - Zip the folder and upload it in Settings → Capabilities → Skills Where a file is given instead of a command, copy the files from the source to that path: https://github.com/jabrena/plinth/tree/HEAD/skills/151-java-performance-jmeter/SKILL.md ## When to use it - Add a JMeter test execution script to a Java project root - Create the src/test/resources/jmeter directory structure for test plans - Configure load test parameters via CLI flags or environment variables - Validate local JMeter availability before setting up tests ## Example prompts - Set up JMeter performance testing for this Java project - Add run-jmeter.sh script and test plan folders for load testing - Configure JMeter load testing support with environment variable overrides ## Source text · SKILL.md · Apache-2.0 Below is the content of a third-party file.

BEGIN THIRD-PARTY FILE c3bbed03b42b2fcb ```text --- name: 151-java-performance-jmeter description: Use when you need to set up JMeter performance testing for a Java project — including creating the run-jmeter.sh script from the exact template, configuring load tests with loops, threads, and ramp-up, or running performance tests from the project root with custom or default settings. This should trigger for requests such as Improve the code with JMeter performance testing; Apply JMeter performance testing; Refactor the code with JMeter performance testing; Add JMeter support; Create a JMeter test plan for a Java service. Part of Plinth Toolkit license: Apache-2.0 metadata: author: Juan Antonio Breña Moral version: 0.19.0 --- # Run performance tests based on JMeter Provide a complete JMeter performance testing solution by creating the run-jmeter.sh script from the exact template, making it executable, and configuring the project structure for load testing. Supports custom loops, threads, ramp-up, and environment variable overrides. **What is covered in this Skill?** - Create run-jmeter.sh in project root from the exact template (no modifications) - Project structure: src/test/resources/jmeter/load-test.jmx, target/ for results - Script options: -l (loops), -t (threads), -r (ramp-up), -g (GUI), -h (help) - Environment variables: JMETER_LOOPS, JMETER_THREADS, JMETER_RAMP_UP - Verify JMeter is installed and available before proceeding **Scope:** Copy the script template verbatim. Do not modify, interpret, or enhance the template content. ## Constraints JMeter must be installed and available in PATH. If not available, show a message and exit. Use only the exact template for the run-jmeter.sh script. - **PREREQUISITE**: Verify JMeter is installed and accessible via `jmeter --version` before creating the script - **CRITICAL**: Copy the run-jmeter.sh template exactly — do not modify, interpret, or enhance - **PERMISSION**: Make the script executable with `chmod +x run-jmeter.sh` - **BEFORE APPLYING**: Read the reference for the exact script template and usage instructions - **EDGE CASE**: If request scope is ambiguous, stop and ask a clarifying question before applying changes - **EDGE CASE**: If required inputs, files, or tooling are missing, report what is missing and ask whether to proceed with setup guidance ## When to use this skill - Improve the code with JMeter performance testing - Apply JMeter performance testing - Refactor the code with JMeter performance testing - Add JMeter support - Create a JMeter test plan for a Java service ## Workflow 1. **Verify JMeter prerequisite** Check `jmeter --version` and stop with guidance if JMeter is not installed or not available in PATH. 2. **Read JMeter reference template** Read `references/151-java-performance-jmeter.md` and use the `run-jmeter.sh` template exactly as provided. 3. **Create script and project structure** ``` END THIRD-PARTY FILE c3bbed03b42b2fcb The third-party file has ended.
