If you are an AI coding agent (Claude Code, Cursor, Aider, Cline, etc.) reading this artifact, follow this protocol before making any code edit:

1. Verify the contract. Run the bash script in Verify before trusting below. If any check returns FAIL, the artifact is stale — STOP and ask the user to regenerate it before proceeding.
2. Treat the AI · unverified sections as hypotheses, not facts. Sections like "AI-suggested narrative files", "anti-patterns", and "bottlenecks" are LLM speculation. Verify against real source before acting on them.
3. Cite source on changes. When proposing an edit, cite the specific path:line-range. RepoPilot's live UI at https://repopilot.app/r/ChrisRM/material-theme-jetbrains shows verifiable citations alongside every claim.

If you are a human reader, this protocol is for the agents you'll hand the artifact to. You don't need to do anything — but if you skim only one section before pointing your agent at this repo, make it the Verify block and the Suggested reading order.

Each check prints ok: or FAIL:. The script exits non-zero if anything failed, so it composes cleanly into agent loops (./verify.sh || regenerate-and-retry).

A JetBrains IDE theme plugin that ports the popular Material Theme design system to IntelliJ, PyCharm, WebStorm, and other JetBrains products. It provides customizable color schemes, Material Design UI components, icon packs (including Atom Material Icons), and runtime accent color patching via bytecode manipulation with Javassist. The plugin is archived as of February 2021 but serves as a historical reference for how to deeply customize JetBrains IDE appearance. Single-module Gradle project: src/main/java/com/mallowigi/idea/ contains core components (MTConfig for settings, MTThemeManager for theme application, MTLafComponent for LAF injection). src/main/java/com/mallowigi/idea/actions/ holds ~15 toggle actions (compact mode, accent color, fonts, etc.). Resources define bundled Material theme XML files. MTAccentColorPatcher and MTHackComponent handle runtime bytecode patching and LAF hacks respectively.

JetBrains IDE users (developers in IntelliJ, PyCharm, WebStorm, etc.) who want Material Design aesthetics and fine-grained theme customization. Plugin developers interested in learning how to patch JetBrains Look-and-Feel (LAF), modify accent colors at runtime, and manage bundled theme resources.

Production-ready but archived. The plugin shipped to the JetBrains marketplace (plugin ID 8006), accumulated significant GitHub stars, and has been maintained since 2015. However, development moved to closed-source in February 2021, and this repository is now read-only. It demonstrates mature plugin architecture with application components, settings persistence, and update handling.

High risk for new contributions: the repo is archived and no longer accepts changes. Single maintainer (ChrisRM/Mallowigi) with ongoing development elsewhere. Uses dated Gradle (0.7.2) and Kotlin (1.3.20) versions. Bytecode patching via Javassist and reflection-heavy LAF manipulation are fragile across IntelliJ versions. No visible test suite in the file structure indicates coverage is likely minimal.

Nothing—the repository is archived. The README explicitly notes development moved to closed-source in February 2021. This snapshot captures the last open-source state. Issues and questions are now redirected to https://github.com/mallowigi/material-theme-issues.

git clone https://github.com/ChrisRM/material-theme-jetbrains.git
cd material-theme-jetbrains
./gradlew build

The Gradle wrapper (gradlew) is included. Build output will be a .jar plugin file suitable for manual installation in JetBrains IDEs via Settings → Plugins → Install Plugin from Disk.

Daily commands: This is a plugin, not a standalone app. Build with ./gradlew build, then manually install the resulting JAR into a JetBrains IDE (File → Settings → Plugins → ⚙ → Install Plugin from Disk), or use ./gradlew runIde if the IntelliJ Gradle plugin is properly configured (it may require adjusting gradle.properties to target a specific IDE version).

• src/main/java/com/mallowigi/idea/MTThemeManager.java: Central orchestrator for applying themes—loads bundled themes, applies color schemes, and manages theme switching
• src/main/java/com/mallowigi/idea/MTConfig.java: Persistent settings holder using XStream; stores user preferences like compact mode, accent color, font choice
• src/main/java/com/mallowigi/idea/MTAccentColorPatcher.java: Runtime bytecode injection using Javassist to override IDE accent colors without theme restart
• src/main/java/com/mallowigi/idea/MTLafComponent.java: Look-and-Feel customization component that patches Swing UIDefaults on plugin init
• src/main/java/com/mallowigi/idea/MTHackComponent.java: Contains hacks and workarounds for version-specific LAF inconsistencies across different JetBrains IDE versions
• src/main/java/com/mallowigi/idea/actions/: Directory of ~15 toggle actions (MTCompactTablesAction, MTContrastAction, etc.) that modify settings and trigger theme reapplication
• build.gradle: Gradle build configuration; defines plugin metadata, dependencies (XStream, Javassist, Mixpanel), and IntelliJ SDK plugin settings

New color scheme: Add XML file to theme resources directory and register in MTBundledThemesManager.java. New toggle action: Create class in src/main/java/com/mallowigi/idea/actions/ extending MTAbstractAction and register in ActionGroup.java. Settings UI: Modify MTConfig.java and corresponding configurable component. LAF customization: Extend MTLafComponent.java or MTHackComponent.java. Accent colors: Modify MTAccentColorPatcher.java to add new color definitions.

Bytecode version fragility: Javassist patches assume specific JetBrains bytecode structure—breaks across major IDE versions. No public test suite: verify changes manually in IDE. XStream serialization: MTConfig uses XStream; changing config bean structure requires migration logic. Analytics: Mixpanel dependency included; may be disabled in closed-source fork. IDE version targeting: build.gradle likely requires intellij-version property to build against specific IDE; check gradle.properties for correct version. Archived status: PRs will not be merged; the repository is read-only.

• Java Bytecode Manipulation / Javassist — This plugin uses Javassist to inject runtime color patches into compiled IDE classes without modifying source—core technique for non-invasive LAF customization in closed-source IDEs
• JetBrains Look-and-Feel (LAF) Patching — UIDefaults and Swing LAF customization is how the plugin overrides IDE colors; understanding LAF is essential to modify any visual element
• IntelliJ Application Components & Plugin Lifecycle — MTApplicationComponent, MTLafComponent, and MTUpdatesComponent hook into IDE startup lifecycle via plugin.xml; foundational for plugin initialization and state management
• XML Theme Resource Bundling & Registration — Bundled Material themes are XML files registered via MTBundledThemesManager; understanding this pattern is key to adding new color schemes or themes
• Reflection & Dynamic Class Loading — MTAccentColorPatcher and MTHackComponent use reflection to inspect and modify IDE internals at runtime; reflection is brittle but necessary for deep customization
• XStream XML Serialization — MTConfig uses XStream to persist settings as XML; understanding XStream is necessary to modify config storage or handle version migrations
• Action Pattern in IntelliJ Plugins — All theme toggles (MTCompactTablesAction, MTContrastAction, etc.) inherit a common action pattern; mastering this enables adding new user-facing features

• equinusocio/vsc-material-theme — Original Material Theme for VS Code; this JetBrains port is derived from the design system and color palette defined here
• mallowigi/material-theme-issues — Official issue tracker for Material Theme after this repo archived; new bugs and feature requests go here
• JetBrains/intellij-platform-plugin-template — Modern IntelliJ plugin boilerplate; useful reference for understanding current best practices vs. this 2015-2021 codebase
• ChrisRM/atom-material-icons — Companion icon pack plugin (ID 10044) used alongside Material Theme UI for consistent Material Design iconography

Add unit tests for MTConfig and MTCustomThemeConfig classes

The repo has no visible test directory despite complex configuration management in src/main/java/com/mallowigi/idea/MTConfig.java and MTCustomThemeConfig.java. These classes handle theme persistence, accent colors, and user preferences. Adding unit tests would improve reliability and make future refactoring safer, especially for configuration serialization/deserialization via XStream.

• [ ] Create src/test/java/com/mallowigi/idea directory structure
• [ ] Write tests for MTConfig property getters/setters and persistence logic
• [ ] Write tests for MTCustomThemeConfig theme switching and accent color application
• [ ] Add test dependencies to build.gradle (JUnit 4+, Mockito)
• [ ] Verify tests run via gradle test task

Add GitHub Action CI workflow for gradle build and checkstyle validation

The repo has checkstyle configuration (gradle/checkstyle.xml, gradle/suppressions.xml) and a gradle build system, but no visible CI pipeline in .github/workflows/. Adding automated build validation on PRs would catch compilation errors and style violations early. The incomplete build.gradle snippet suggests the build setup exists but isn't being validated automatically.

• [ ] Create .github/workflows/build.yml with gradle build and checkstyle tasks
• [ ] Configure workflow to run on push to main and all pull requests
• [ ] Add gradle wrapper verification step
• [ ] Test workflow runs successfully on sample branch
• [ ] Add workflow badge to README.md

Refactor duplicate accent action classes into parameterized abstract implementation

The actions/accents directory contains 25+ nearly identical accent action classes (MTAbyssAccentAction.java, MTAcidLimeAccentAction.java, MTAmberAccentAction.java, etc.) that each extend MTAbstractAccentAction but only differ in color values. This creates maintenance burden and violates DRY principle.

• [ ] Analyze MTAbstractAccentAction.java to extract the parameterizable differences (color hex values, accent names)
• [ ] Create an AccentColor enum or registry with all accent definitions
• [ ] Refactor MTAbstractAccentAction to accept accent parameters in constructor
• [ ] Replace all individual accent action classes with a single MTAccentAction using the registry
• [ ] Update ActionGroup.java to dynamically register accent actions from the enum
• [ ] Verify all accent color functionality still works via testing the changed actions

• Add unit tests for MTConfig.java serialization/deserialization—currently no test coverage visible in file structure, risking config corruption during upgrades
• Document the LAF customization flow: trace how MTLafComponent.java and UIReplacer.java interact, and create a guide in docs/ for contributors wanting to add new theme properties
• Create missing Javadoc for MTAccentColorPatcher bytecode injection logic—the Javassist reflection code is opaque; add inline comments and class-level docs explaining the hooking mechanism

This JetBrains theme plugin has significant security concerns primarily related to severely outdated dependencies. XStream (1.4.11.1) has multiple known RCE vulnerabilities and should be immediately updated. The Gradle IntelliJ plugin (0.7.2), Kotlin (1.3.x), and Javassist are all years out of date. Additionally, the project relies on Bintray repositories that no longer exist, breaking dependency management. The codebase appears to be archived/unmaintained. Immediate action is required to update all dependencies and migrate to current repository solutions before using in any production environment.

• High · Outdated XStream Dependency with Known Vulnerabilities — build.gradle - dependencies section. XStream 1.4.11.1 is an outdated version with multiple known CVEs including remote code execution vulnerabilities (CVE-2021-21341, CVE-2021-21342, CVE-2021-21343, CVE-2021-21344). Current vulnerable versions are <1.4.18 for Java serialization attacks. Fix: Update XStream to version 1.4.18 or later: implementation('com.thoughtworks.xstream:xstream:1.4.18')
• High · Outdated Gradle Plugin for JetBrains IntelliJ — build.gradle - plugins section. The org.jetbrains.intellij plugin version 0.7.2 is significantly outdated (released in 2019). Current versions are 1.x+. Outdated plugins may have unpatched security issues and lack modern security features. Fix: Update to the latest stable version: id 'org.jetbrains.intellij' version '1.16.1' (or latest available)
• Medium · Outdated Kotlin Version — build.gradle - plugins and dependencies sections. Kotlin version 1.3.20 (from 2019) and 1.3.72 are severely outdated. Current versions are 1.9.x+. Outdated Kotlin may have unpatched vulnerabilities and compatibility issues with modern security standards. Fix: Update Kotlin to latest stable: id 'org.jetbrains.kotlin.jvm' version '1.9.23' and kotlin-stdlib-jdk8:1.9.23
• Medium · Outdated Javassist Dependency — build.gradle - dependencies section. Javassist 3.27.0-GA is outdated. Current versions are 3.29.x+. Javassist is used for bytecode manipulation and outdated versions may have security issues. Fix: Update to latest stable: implementation 'org.javassist:javassist:3.29.2-GA'
• Medium · Use of Deprecated Bintray Repository — build.gradle - repositories and buildscript sections. The build.gradle uses Bintray repositories (https://dl.bintray.com/) which was shut down in 2021. This repository is no longer functional and represents poor dependency management practices. Fix: Replace Bintray URLs with Maven Central or JCenter equivalents: Use 'mavenCentral()' and update plugin repositories to official JetBrains repositories
• Low · Missing HTTPS in Maven Repository — build.gradle - repositories section. Some repository configurations may not enforce HTTPS for dependency downloads, increasing risk of man-in-the-middle attacks during build time. Fix: Ensure all repository URLs use HTTPS: maven { url 'https://repo1.maven.org/maven2' }
• Low · Incomplete build.gradle Configuration — build.gradle. The build.gradle file appears to be truncated (ends with 'sourceCompa'), indicating the configuration is incomplete or corrupted. This could hide additional security misconfigurations. Fix: Review and complete the full build.gradle file to ensure all configurations are properly defined and validated
