Managing dependencies

What it does

Maven is an agent skill from skjolber/3d-bin-container-packing. Maven build expertise for this multi-module Java project. Use when working with pom.xml files, managing dependencies, running builds or tests for specific modules, configuring or troubleshooting plugins (surefire, jacoco, shade, spotless, pitest, owasp), regenerating OpenAPI sources, building the JMH benchmark JAR, or releasing to Maven Central.

Its SKILL.md is about 890 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Security, covering Web application vulnerabilities, OpenAPI specifications and Test coverage. It works with Java and OpenAPI. The repository describes itself as: A variant of the Largest Area Fit First (LAFF) algorithm + brute force algorithm. The licence is Apache-2.0.

What it can do on your machine

Read from SKILL.md and the folder at commit 6072d15. 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
Shell commands in SKILL.md call:
- mvn
- java
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

Maven loads about 886 tokens when it runs. Until then it costs about 88 tokens; SKILL.md has 215 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~88
When it runs · the whole SKILL.md, loaded when a task matches: ~886

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); files beside SKILL.md are not scanned.

Maven Multi-Module Build

This project is a Maven multi-module build. The root pom.xml is the parent; all dependency versions and plugin versions are declared there as properties.

Module Names (for `-pl`)

`-pl` value	Description
`api`	Public interfaces and data model
`points`	Free-space point tracking
`core`	Packager algorithm implementations
`test`	Shared test utilities
`jmh`	JMH benchmark suite
`open-api/open-api-model`	Generated Jackson model
`open-api/open-api-server`	Generated Spring server stubs
`open-api/open-api-client`	Generated Apache HttpClient 5 stubs
`open-api/open-api-test`	Shared open-api test utilities
`visualizer/api`	Visualizer JSON contract types
`visualizer/algorithm`	Algorithm state capture
`visualizer/packaging`	Packing result → JSON conversion

Common Commands

bash

# Build and test one module (and its dependencies)
mvn test -pl <module> -am

# Build without running tests
mvn package -pl <module> -am -DskipTests

# Install all modules
mvn install

# Install everything, skip tests
mvn install -DskipTests

Plugin Reference

Surefire — running tests

bash

mvn test -pl <module> -am

Version is maven-surefire-plugin.version in root pom.xml.

JaCoCo — code coverage

bash

mvn test jacoco:report -pl <module> -am
# Report lands in target/site/jacoco/index.html

Spotless — code formatting

bash

mvn spotless:check          # fail if formatting is off
mvn spotless:apply          # auto-fix formatting

Maven Shade — fat JAR (jmh module)

bash

mvn package -pl jmh -am -DskipTests
java -jar jmh/target/benchmarks.jar

OpenAPI Generator — regenerate model/server/client

bash

# All three at once
mvn generate-sources -pl open-api/open-api-model,open-api/open-api-server,open-api/open-api-client

# Individual module
mvn generate-sources -pl open-api/open-api-model

Source of truth is open-api/3d-api.yaml. Never hand-edit generated sources.

PiTest — mutation testing

bash

mvn test-compile org.pitest:pitest-maven:mutationCoverage -pl <module> -am

OWASP Dependency Check

bash

mvn dependency-check:check -pl <module>

Dependency Management Rules

All versions live in root pom.xml as <properties> — never hardcode a version in a child POM.
Use ${property.version} references in child POMs.
<dependencyManagement> in the root POM controls all third-party and inter-module versions.
Inter-module dependencies use ${project.version}.

Key Version Properties

Property	Controls
`java.version`	Java 17 source/target
`junit.version`	JUnit Jupiter
`mockito.version`	Mockito
`assertj.version`	AssertJ
`jmh.version`	JMH framework
`jacoco-maven-plugin.version`	JaCoCo
`maven-surefire-plugin.version`	Surefire
`spotless.version`	Spotless formatter
`pitest.version`	PiTest mutation testing

Release to Maven Central

Uses maven-release-plugin + maven-gpg-plugin + Sonatype Central Portal plugin.

bash

mvn release:prepare
mvn release:perform

Questions about Maven

What does Maven do?

Maven build expertise for this multi-module Java project. An agent skill from skjolber/3d-bin-container-packing. Maven is an agent skill from skjolber/3d-bin-container-packing. Maven build expertise for this multi-module Java project.

When should I use Maven?

Maven fits situations like: working with pom.xml files; managing dependencies; tests for specific modules; troubleshooting plugins (surefire.

How do I install Maven in Claude Code?

Run `npx skills add skjolber/3d-bin-container-packing --skill maven -a claude-code`. Or copy the skill folder (skills/maven in skjolber/3d-bin-container-packing) into .claude/skills/maven in your project. Claude Code loads it when a task matches its description.

How do I install Maven in Codex?

Run `npx skills add skjolber/3d-bin-container-packing --skill maven -a codex`. Or copy the skill folder (skills/maven in skjolber/3d-bin-container-packing) into .agents/skills/maven in your project. Codex loads it when a task matches its description.

Can I use Maven 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 skjolber/3d-bin-container-packing --skill maven -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/maven, .gemini/skills/maven, .github/skills/maven and .opencode/skills/maven in your project.

What does Maven need to run?

Going by SKILL.md and its folder, Maven needs the command-line tools its instructions call (mvn and java).

Does Maven 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 Maven 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. Review the folder before installing.

What licence does Maven use?

Maven is published under the Apache-2.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Maven use?

About 886 tokens (SKILL.md is roughly 3.5k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.

What are the alternatives to Maven?

Skills that share tags, products or a category with Maven: 703 Technologies Fuzzing Testing (jabrena/plinth, 447 stars), Oryxos Init (oryx-labs/oryxos, 186 stars), API Security Review (OWASP/secure-agent-playbook, 187 stars) and Implementing API Security Testing With 42crunch (mukul975/Anthropic-Cybersecurity-Skills, 34k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.

Who maintains Maven?

skjolber (a GitHub user) maintains it in skjolber/3d-bin-container-packing, which has 569 GitHub stars. The repository was last updated on October 8, 2026.
