Gradle Plugin Version Bump

Bumps the dev.nx.gradle.project-graph plugin to a new version. This is a recurring task that touches 5 files in an identical pattern every time.

Required Inputs

Collect these values from the master branch before starting:

1. NEW_VERSION - the version we want to bump to Example: OLD_VERSION: 0.1.15 => NEW_VERSION: 0.1.16 You can find this value by looking at the OLD_VERSION specified in packages/gradle/project-graph/build.gradle.kts in the version field.
   The NEW_VERSION will be the OLD_VERSION + 1.

2. NX_MIGRATION_VERSION - the version of Nx that will trigger our version bump migration Example: OLD_VERSION: 22.7.0-beta.0 => NEW_VERSION: 22.7.0-beta.1 You can find this value by looking at the nx version in package.json under devDependencies. The NEW_VERSION will be the OLD_VERSION + 1.

3. MIGRATION_FOLDER - the folder name under packages/gradle/src/migrations/ that will contain our migration files Example: NEW_VERSION: 22.7.0-beta.1 => MIGRATION_FOLDER: 22-7-0 Take the version and replace all the dots with hyphens and remove the beta or rc suffix.

Steps

1. Update the version constant

File: packages/gradle/src/utils/versions.ts

Change gradleProjectGraphVersion to the new version:

export const gradleProjectGraphVersion = 'NEW_VERSION';

2. Update build.gradle.kts

File: packages/gradle/project-graph/build.gradle.kts

Update the version on line 13:

version = "NEW_VERSION"

3. Create migration TypeScript file

File: packages/gradle/src/migrations/MIGRATION_FOLDER/change-plugin-version-NEW_VERSION.ts

Determine the previous version by reading the current gradleProjectGraphVersion from packages/gradle/src/utils/versions.ts before modifying it.

Template:

import { Tree, readNxJson } from '@nx/devkit';
import { hasGradlePlugin } from '../../utils/has-gradle-plugin';
import { addNxProjectGraphPlugin } from '../../generators/init/gradle-project-graph-plugin-utils';
import { updateNxPluginVersionInCatalogsAst } from '../../utils/version-catalog-ast-utils';

/* Change the plugin version to NEW_VERSION
 */
export default async function update(tree: Tree) {
  const nxJson = readNxJson(tree);
  if (!nxJson) {
    return;
  }
  if (!hasGradlePlugin(tree)) {
    return;
  }

  const gradlePluginVersionToUpdate = 'NEW_VERSION';

  // Update version in version catalogs using AST-based approach to preserve formatting
  await updateNxPluginVersionInCatalogsAst(tree, gradlePluginVersionToUpdate);

  // Then update in build.gradle(.kts) files
  await addNxProjectGraphPlugin(tree, gradlePluginVersionToUpdate);
}

4. Create migration documentation file

File: packages/gradle/src/migrations/MIGRATION_FOLDER/change-plugin-version-NEW_VERSION.md

Replace PREV_VERSION with the version that was current before this bump.

Template:

#### Change dev.nx.gradle.project-graph to version NEW_VERSION

Change dev.nx.gradle.project-graph to version NEW_VERSION in build file

#### Sample Code Changes

##### Before

\```text title="build.gradle"
plugins {
id "dev.nx.gradle.project-graph" version "PREV_VERSION"
}
\```

##### After

\```text title="build.gradle"
plugins {
id "dev.nx.gradle.project-graph" version "NEW_VERSION"
}
\```

5. Add migration entry to migrations.json

File: packages/gradle/migrations.json

Add a new entry at the end of the generators object (before the closing }), following the existing pattern:

"change-plugin-version-NEW_VERSION": {
  "version": "NX_MIGRATION_VERSION",
  "cli": "nx",
  "description": "Change dev.nx.gradle.project-graph to version NEW_VERSION in build file",
  "factory": "./src/migrations/MIGRATION_FOLDER/change-plugin-version-NEW_VERSION"
}

The migration key uses the version with hyphens replacing dots (e.g., 0-1-16).

Verification

Run:

nx run-many -t test,build,lint -p gradle
