Build from source

Step 0: Install the necessary tools

💡 RECOMMENDED

Nix development environment: A devbox configuration is provided to automatically setup all the tools below. Read more in here.

To build and test all packages of the Apache KIE Tools project, you're going to need:

• Node 20 (To install, follow these instructions: https://nodejs.org/en/download/package-manager/)
• pnpm 9.3.0 (To install, follow these instructions: https://pnpm.io/installation#using-npm)
• Maven 3.9.6
• Java 17
• Go 1.22.9 (To install, follow these instructions: https://go.dev/doc/install)
• Python 3.12 (To install, follow these instructions: https://www.python.org/downloads/)
• Helm 3.13.3 (To install, follow these instructions: https://helm.sh/docs/intro/install/)
• Make
• xmllint (To install, follow these instructions: https://www.baeldung.com/linux/xmllint)
• bash 5.x (On Linux or Nix you should be fine. On macOS, follow these instructions to use zsh: https://support.apple.com/102360)

ℹ️ NOTE

If you plan on building container images, make sure you have a working Docker setup. Setting KIE_TOOLS_BUILD__buildContainerImages=true will also be necessary.

Step 1: Bootstrap

Bootstrapping installs the necessary dependencies for each package.

• pnpm bootstrap --> Will bootstrap all packages
• pnpm bootstrap [pnpm-filter] --> Will bootstrap packages filtered by pnpm filter

• E.g.,

  pnpm bootstrap -F dmn-editor... bootstraps the dmn-editor package and its dependencies.

ℹ️ NOTE

If you plan on running Playwright tests, set the PLAYWRIGHT_BASE__installDeps environment variable to true before running the command above.

PLAYWRIGHT_BASE__installDeps=true pnpm bootstrap.

This will install all Playwright dependencies (such as browsers engines and OS-specific libraries).

Step 2: Build

• Dev

  • pnpm -r build:dev
    • Will build all packages for development. Skipping linters, tests, minifiers etc.
  • pnpm [pnpm-filter] build:dev
    • Will build packages filtered by pnpm filter

  • E.g.,

    pnpm -F dmn-editor... build:dev builds the dmn-editor package and its dependencies.

• Prod

  • pnpm -r build:prod
    • Will build all packages for production. Optimizers will run, binaries will be produced for multiple architectures etc.
  • pnpm [pnpm-filter] build:prod
    • Will build packages filtered by pnpm filter

  • E.g.,

    pnpm -F dmn-editor... build:prod builds the dmn-editor package and its dependencies.

• Changed

  • pnpm -F '...[HEAD]' build:dev; or
  • pnpm -F '...[HEAD]' build:prod
    • Will build changed and affected packages based on your local changes. Useful for verifying that you didn't break anything.

ℹ️ NOTE

The Apache KIE Tools build is parameterized by several Environment Variables. For an extensive list of these variables, please see the list printed by the bootstrap step.

• To enable the examples build: export KIE_TOOLS_BUILD__buildExamples=true
• To enable container images build: export KIE_TOOLS_BUILD__buildContainerImages=true
• To enable E2E tests: export KIE_TOOLS_BUILD__runEndToEndTests=true

ℹ️ NOTE

Final artifacts will be in {packages,examples}/*/dist directories.

Reproducible Builds for maven-based packages

It is mandatory that any maven-based package that releases artifacts runs Reproducible Builds to build it's artifacts, in this case, in our build:prod scripts.

@kie-tools/maven-base provides the reproducible-build maven profile to enable Reproducible Builds in our builds. To use it follow the steps:

• Make sure the package.json depends on @kie-tools/maven-base:

{
  "dependencies": {
    "@kie-tools/maven-base": "workspace:*"
  }
}

• Make the package pom.xml has kie-tools-maven-base as a parent and declares the project.build.outputTimestamp property like:

<project>
  <parent>
    <groupId>org.kie</groupId>
    <artifactId>kie-tools-maven-base</artifactId>
    <version>${revision}</version>
    <relativePath>./node_modules/@kie-tools/maven-base/pom.xml</relativePath>
  </parent>
  ...
  <properties>
    <project.build.outputTimestamp>2024-01-12T00:00:00Z</project.build.outputTimestamp>
  </properties>
  ...
<projec>

• In your package.json scripts, enable the Reproducible Build profile adding the -Dreproducible argument in build:prod scripts, like:

{
  "scripts": {
    "build:prod": "pnpm lint && run-script-os",
    "build:prod:darwin:linux": "mvn clean deploy [...other maven options...] -Dreproducible",
    "build:prod:win32": "pnpm powershell \"mvn clean deploy [...other maven options...] `-Dreproducible\""
  }
}

IMPORTANT: the current version of the maven-artifact-plugin (3.4.1) used in kie-tools bans the maven-flatten-plugin that we use to generate deployable artifacts using the dynamic ${revision} variable. You can check the full list of banned plugins here. The issue that caused the ban flatten-maven-plugin/issues/256 was a result of change in maven behaviour between v3.8.1 and v3.8.2, and isn't a problem on the maven-flatten-plugin. Actually, in later versions of the maven-artifact-plugin the ban got revoked. Having this in mind, and due to the fact that kie-tools requires newer maven versions, our Reproducible Builds require temporarily overriding the list of banned plugins, until we upgrade to a newer maven-artifact-plugin version. This will be addressed by apache/incubator-kie-issues#1371

Applications

The Apache KIE Tools project contains several applications. To develop each one of them individually, refer to the instructions below.

VS Code Extension (DMN, BPMN, SceSim, and PMML Editors)

1. After you've successfully built the project following the instructions above, open the packages/kie-editors-dev-vscode-extension folder on VS Code. Use a new VS Code window so that the packages/kie-editors-dev-vscode-extension folder shows up as root in the VS Code explorer.
2. From there, you can Run the extension or the end-to-end tests by using the Debug menu/section. You can also use the respective shortcuts (F5 to start debugging, for instance).
3. NOTE: To run the VS Code extension in development mode, you need webpack and webpack-cli to be globally installed on NPM. Normally you can do that with npm install -g webpack@^5.92.1 webpack-cli@^4.10.0, but sudo may be required depending on your installation.
4. Remember! If you make changes to any package other than packages/kie-editors-dev-vscode-extension, you have to manually rebuild them before relaunching the extension on VS Code.

VS Code Extension (Serverless Workflow Editor)

1. After you've successfully built the project following the instructions above, open the packages/serverless-workflow-vscode-extension folder on VS Code. Use a new VS Code window so that the packages/serverless-workflow-vscode-extension folder shows up as root in the VS Code explorer.
2. From there, you can Run the extension or the end-to-end tests by using the Debug menu/section. You can also use the respective shortcuts (F5 to start debugging, for instance).
3. Remember! If you make changes to any package other than packages/serverless-workflow-vscode-extension, you have to manually rebuild them before relaunching the extension on VS Code.

Chrome Extension (DMN, BPMN, and SceSim Editors)

1. After you've successfully built the project following the instructions above, open the packages/chrome-extension-pack-kogito-kie-editors folder on your favourite IDE. You can import the entire repo as well if you want to make changes to other packages.
2. Run pnpm build:dev on packages/chrome-extension-pack-kogito-kie-editors. This will create a version of the Chrome Extension that fetches the envelope locally.
3. Open a terminal and run pnpm start on packages/chrome-extension-pack-kogito-kie-editors. This will start a webpack serve instance with the editors and their envelope. We use that because we don't pack the Chrome Extension bundle with the editors inside. Instead, we fetch them from GitHub pages.
4. You also have to enable invalid certificates for resources loaded from localhost in your browser. To do that, go to chrome://flags/#temporary-unexpire-flags-m118 in your Chrome browser, enable this flag and restart browser. Then go to chrome://flags/#allow-insecure-localhost in your Chrome browser and enable also this flag. Alternativelly, you can go to https://localhost:9001 and add an exception.
5. Open Chrome and go to chrome://extensions. Enable "Developer mode" in the top-right corner and click on "Load unpacked". Choose the packages/chrome-extension-pack-kogito-kie-editors/dist folder.
6. From now on you can use the development version of the extension. Remember! After each change, you have to rebuild the changed modules and hit the "Refresh" button of the extension card.

Chrome Extension (Serverless Workflow Editor)

1. After you've successfully built the project following the instructions above, open the packages/chrome-extension-serverless-workflow-editor folder on your favourite IDE. You can import the entire repo as well if you want to make changes to other packages.
2. Run pnpm build:dev on packages/chrome-extension-serverless-workflow-editor. This will create a version of the Chrome Extension that fetches the envelope locally.
3. Open a terminal and run pnpm start on packages/chrome-extension-serverless-workflow-editor. This will start a webpack serve instance with the editors and their envelope. We use that because we don't pack the Chrome Extension bundle with the editors inside. Instead, we fetch them from GitHub pages.
4. You also have to enable invalid certificates for resources loaded from localhost in your browser. To do that, go to chrome://flags/#temporary-unexpire-flags-m118 in your Chrome browser, enable this flag and restart browser. Then go to chrome://flags/#allow-insecure-localhost in your Chrome browser and enable also this flag. Alternativelly, you can go to https://localhost:9000 and add an exception.
5. Open Chrome and go to chrome://extensions. Enable "Developer mode" in the top-right corner and click on "Load unpacked". Choose the packages/chrome-extension-serverless-workflow-editor/dist folder.
6. From now on you can use the development version of the extension. Remember! After each change, you have to rebuild the changed modules and hit the "Refresh" button of the extension card.

KIE Sandbox

1. After you've successfully built the project following the instructions above, go to packages/online-editor.
2. Open a terminal and run pnpm start. This will start a webpack serve instance with the Online Editor resources.
3. From now on you can use the development version of the Online Editor by accessing https://localhost:9001.
4. Run the CORS Proxy by running pnpm start at packages/cors-proxy.

Serverless Logic Web Tools

1. After you've successfully built the project following the instructions above, go to packages/serverless-logic-web-tools.
