### Automatic Branch Analysis & Merge Request Analysis

By default, this template tries to auto-detect and use [Pull Request Analysis](https://docs.sonarqube.org/latest/analysis/pull-request/) or [Branch Analysis](https://docs.sonarqube.org/latest/branches/overview/) (depending on the context).
This template relies on SonarScanner's [GitLab integration](https://docs.sonarqube.org/latest/analysis/gitlab-integration), that is able to auto-detect whether to launch Branch Analysis or Merge Request Analysis
from GitLab's environment variables.

Those is a great SonarQube features but it assumes one of the following conditions:
:warning: This feature also depends on your SonarQube server version and license.
If using Community Edition, you'll have to install the [sonarqube-community-branch-plugin](https://github.com/mc1arke/sonarqube-community-branch-plugin) to enable automatic Branch & Merge Request analysis (only works from SonarQube version 8).

* you are using a [Developer Edition](https://www.sonarqube.org/developer-edition/) version,
* or you are using Community Edition with an opensource plugin emulating those features, such as [sonarqube-community-branch-plugin](https://github.com/mc1arke/sonarqube-community-branch-plugin).

If you're not in one of those cases, then you shall disable this feature by setting `SONAR_BRANCH_ANALYSIS_DISABLED`.

If you leave the feature enabled, the template will try to auto-detect whether the current branch is associated to an open Merge Request or not:

1. if you're running [Merge Request pipelines](https://docs.gitlab.com/ee/ci/yaml/workflow.html#switch-between-branch-pipelines-and-merge-request-pipelines), 
   then the template will automatically detect the MR,
2. if you're running [branch pipelines](https://docs.gitlab.com/ee/ci/yaml/workflow.html#switch-between-branch-pipelines-and-merge-request-pipelines)
   instead, the template will have to call GitLab APIs to determine whether the current branch is associated to an open Merge Request.
   This will only be possible if you provided `SONAR_GITLAB_TOKEN`. 
   Otherwise, a simple [Branch Analysis](https://docs.sonarqube.org/latest/branches/overview/) is performed on the current branch.
:warning: Merge Request Analysis only works if you're running [Merge Request pipeline](https://docs.gitlab.com/ee/ci/yaml/workflow.html#switch-between-branch-pipelines-and-merge-request-pipelines) strategy (default).
