Security Misconfiguration

Restrict the workflow token to read-only contents.

This workflow does not declare permissions, so GITHUB_TOKEN access depends on repository or organization defaults. It checks out repository code and runs Maven and Gradle commands. Limit the token to contents: read. Set persist-credentials: false when later steps do not need Git authentication.

Pass workflow inputs through env and validate them before use.

${{ github.event.inputs.version }} and ${{ github.event.inputs.nextVersion }} are expanded directly into shell text. A workflow dispatcher can supply shell metacharacters that execute before Maven or sed runs. The job has contents: write permission and later passes release credentials to JReleaser. Validate the version values and quote their uses.

Update the statement that the module is excluded from the Maven reactor.

The root pom.xml now lists refactor-first-gradle-plugin as a module. This statement is stale. Also update the same claim in the header comment of .github/workflows/gradle.yml and in plans/finish-pr-157-v2.md, or restore the exclusion.

carries the class-file-69 `rewrite-java-25` jar, whose bytecode Gradle ≤ 9.0
cannot instrument):

- Build & test: `cd refactor-first-gradle-plugin && ./gradlew clean build`
- Plugin id: `org.hjug.refactorfirst`; tasks `refactorFirstHtmlReport`,
`refactorFirstSimpleHtmlReport`, `refactorFirstCsvReport`,
`refactorFirstJsonReport` (task/output contract: see
`plans/finish-pr-157-v2.md` §1; verified by `RefactorFirstPluginTest`
[ProjectBuilder] and `RefactorFirstPluginFunctionalTest` [TestKit]).
- **Thin jar — no shadow plugin, no `minimizeJar`.** The plugin resolves
`org.hjug.refactorfirst.report:report` and its transitives as real jars, so
`codebase-graph-builder`'s JEP 238 `META-INF/versions/25` entries stay intact
(shading with minimize would strip them and break Java 25 parsing).
- **No `getProject()` in `@TaskAction`** (Gradle 9 / configuration-cache
hygiene); values are captured at registration time. Tasks declare no
`@Input`/`@Output` and `getOutputs().upToDateWhen(t -> false)` — they always
run (guarded by `configurationCacheRunHasNoProblems` and `tasksRunEveryTime`).
- `refactorFirstJsonReport` must invoke
`org.hjug.refactorfirst.report.JsonGenerator` (the Maven plugin's generator),
**never** `org.hjug.refactorfirst.report.json.JsonReportExecutor`.
- Version sync: `refactor-first-gradle-plugin/gradle.properties`
`refactorFirstVersion` must equal the Maven `project.version`; `gradle.yml`
fails the build on drift, and `release.yml` bumps both in the same commit.
Release order: `report` et al. must be on Maven Central **before**
`./gradlew publishPlugins` (maintainer-only) publishes the thin plugin jar.
- Local dev: run `mvn install` (or `-pl report -am`) first so `mavenLocal()`
can resolve the SNAPSHOT `report` dependency, **then** `./gradlew
publishToMavenLocal` so consuming builds can resolve the plugin marker
`org.hjug.refactorfirst:org.hjug.refactorfirst.gradle.plugin` from
`mavenLocal()`. Consumers need `mavenLocal()` in `pluginManagement
repositories`; never point `resolutionStrategy.eachPlugin.useModule` at the
marker coordinates (that module is POM-only) — either omit
`resolutionStrategy` or point `useModule` at the implementation module
`org.hjug.refactorfirst.plugin:refactor-first-gradle-plugin`.

## But I'm using Gradle / my project layout isn't typical!
I plan to create a Gradle plugin and (possibly) support non-conventional project structures in the future, but in the meantime you can create a dummy POM file in the same directory as your .git directory to show your project's name in the report:
## Using the Gradle Plugin

Apply the plugin in `build.gradle.kts` (or `build.gradle`):

```kotlin
plugins {
id("org.hjug.refactorfirst") version "0.11.0"
}
```

Tasks (run with `./gradlew <task>` on the project the plugin is applied to):

|Task| Output |
|----|----------------------------------------------------------------------|
|`refactorFirstHtmlReport`| `build/reports/refactorfirst/refactor-first-report.html` |
|`refactorFirstSimpleHtmlReport`| `build/reports/refactorfirst/refactor-first-report.html` |
|`refactorFirstCsvReport`| `build/reports/refactorfirst/RefFirst_P<name>_PV<version>_PD<date>.csv` |
|`refactorFirstJsonReport`| `.refactorfirst/refactor-first.json` |

Reports are always regenerated: the tasks never report `UP-TO-DATE` and are never loaded `FROM-CACHE`.

The `refactorFirst` extension accepts the same options as the Maven plugin (described above), plus an output override:

```kotlin
refactorFirst {
showDetails = false
backEdgeAnalysisCount = 50
analyzeCycles = true
minifyHtml = false
excludeTests = true
testSourceDirectory = "src/test"
projectName = "My Project" // defaults to the Gradle project name
projectVersion = "1.0-SNAPSHOT" // defaults to the Gradle project version
outputDirectory = "build/rf" // HTML/CSV only; the JSON report always writes to .refactorfirst
}
```

## But my project layout isn't typical!
If your project layout isn't conventional, you can create a dummy POM file in the same directory as your .git directory to show your project's name in the report:

```xml
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
