## Overview

The project consists of two components:

* a .NET project that produces an assembly that plugs in to OmniSharp

* a Java project that produces a Sonar plugin jar that will be consumed by SonarLint in Rider and VSCode

## Building locally

The Azure pipeline builds, tests and packages both components.

Use the following commands to build locally:

### Download OmniSharp fork

`mvn generate-resources -Pdownload-omnisharp-for-building`

### Build .NET solution

Set the `ARTIFACTORY_USER` (your Sonar email) and `ARTIFACTORY_PASSWORD` (your repox credentials) environment variables.

You may need to restart your computer after these variables are set.

`dotnet build omnisharp-dotnet/SonarLint.OmniSharp.DotNet.Services.sln`

### Java plugin

The Java component depends on the .NET component, so the .NET component must be built first.

`mvn clean verify`
