#### Automatic Branch Analysis & Pull Request Analysis
### 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).
: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).

If you're not in one of those cases, then you shall disable this feature by setting `SONAR_BRANCH_ANALYSIS_DISABLED`.
### Configuring SonarQube project key, project name and other parameters

If you leave the feature enabled, if `SONAR_GITLAB_TOKEN` is provided, the template will try to autodetect (using GitLab APIs) an opened merge request matching the current branch:
You shall define your SonarQube project key and project name in a `sonar-project.properties` file located at the root of your repository (as respectively `sonar.projectKey` and `sonar.projectName` entries), although they might alternately be set as `$SONAR_PROJECT_KEY` and `$SONAR_PROJECT_NAME` variables.

* If one is found, a SonarQube [Pull Request Analysis](https://docs.sonarqube.org/latest/analysis/pull-request/) will be made.
* Otherwise, a simple [Branch Analysis](https://docs.sonarqube.org/latest/branches/overview/) is performed on the current branch.
Note that when not explictly set, the template will use `$CI_PROJECT_PATH_SLUG` and `$CI_PROJECT_PATH` as fallback project key and project name.

### About Sonar GitLab plugin
The `sonar-project.properties` file is also the recommended way to configure other SonarQube [analysis parameters](https://docs.sonarqube.org/latest/analysis/analysis-parameters/)
as well as [language specific parameters](https://docs.sonarqube.org/latest/analysis/languages/overview/).

The [Sonar GitLab plugin](https://github.com/gabrie-allaigre/sonar-gitlab-plugin) uses the GitLab APIs to inline comments
into your commits directly in GitLab for each new anomaly.

As explained above, this template automatically enables the Sonar GitLab plugin if `SONAR_GITLAB_TOKEN` is set.
It will then simply append the `SONAR_GITLAB_ARGS` (overridable) to the SonarQube analysis arguments.

Comments added to GitLab will appear as owned by the user associated to the GitLab [access token](https://docs.gitlab.com/ee/user/profile/personal_access_tokens.html).

### How should I configure other SonarQube arguments ?

The simplest and recommended way to configure other SonarQube [analysis arguments](https://docs.sonarqube.org/latest/analysis/analysis-parameters/)
(and even [language specific args](https://docs.sonarqube.org/latest/analysis/languages/overview/)) is to use a
`sonar-project.properties` file at the root of your repository.
Each _to-be-continuous_ build template shall briefly document the supported language-specific SonarQube parameters.
