How to Contribute

Start by opening an issue using one of the issue templates, or propose a change by submitting a pull request (including a detailed pull request description).

Running the Project

Prerequisites

1. Install nvm
2. Install Java version >= 17
3. Select Node version: nvm use
4. If using an Apple M1:
   • Add npm_arch=x64 to $HOME/.gradle/gradle.properties
   • Add protoc_platform=osx-x86_64 to $HOME/.gradle/gradle.properties
5. If using Windows:
   • The extension uses grpc-tools@1.12.x dependency which does not work out-of-the-box in Windows (check this issues for details), so you'll need to install some aditional DLLs if the project build is failed.
   • Download and start Build Tools for Visual Studio 2022.
   • Go to the Individual Components tab and select the following:
     • MSVC v143 - VS 2022 C++ x64/x86 build tools (latest) (replacing x64/x86 with your arch)
     • Windows Universal CRT SDK
   • Click Install to add the components.

Build Gradle Build Server & Gradle Project Importer

Before proceeding with the build steps for Build Task Server & Language Server, you need to build the Gradle Build Server and its client (Gradle Project Importer) first.

1. cd extension
2. git clone https://github.com/microsoft/build-server-for-gradle.git
3. Build the Importer and Build Server jars: ../gradlew buildJars

Build Task Server & Language Server

After building the Gradle Build Server and its client, proceed with the following steps.

1. Change directory to the root of the project

2. Build project files: ./gradlew build

Running the build for the first time can take a bit of time, but subsequent builds should be fast.

Debugging Gradle plugin

The extension uses a Gradle plugin (com.microsoft.gradle.GradlePlugin) to get a lot of information from your project's Gradle build. If you want to debug the Gradle plugin, you can follow these steps:

1. Run vscode launch configuration Debug Extension & Gradle Plugin.
2. Run vscode launch configuration Attach to Gradle Plugin.

Note: There is a known issue that when the Gradle project stores in a sub-folder of the root folder, the Attach to Gradle Plugin will fail to attach. See #1237.

Debugging Gradle Server

1. Run vscode launch configuration Debug Gradle Server & Extension.
2. Run vscode launch configuration Attach to Gradle Server when you notice the Gradle: Connecting... message in the bottom status bar.

Note: If [error] Error connecting to gradle server: Failed to connect before the deadline appears in the Gradle for Java output channel, it indicates that the connection attempt to the Gradle Server was too slow. The GradleBuildClient requires an active Gradle Server to successfully establish a connection. If you encounter this issue, please retry the connection promptly to avoid this error.

Development Workflow

Open the root of the project in VS Code.

Open the Debug panel, and select one of the debug tasks, for example Debug Extension, or any of the test launch configurations.

You can also run ./gradlew build testVsCode to run all tests.

Code Style

Prettier is used to lint & format most files.

• Lint: ./gradlew lint
• Fix linting issues: ./gradlew format
