SonarQube Configuration For .NET Core Web API

When multiple developers are working on the same project, it's good to have a code review. SonarQube is a tool through which we can evaluate our code. Here, for demo purposes, we are going to evaluate the web API which is built on .NET Core.
Let's see step by step implementation.
In order to run SonarQube, we need to install JAVA in our local system.
 
Refer to the below link to download JAVA installer and install JAVA.
https://www.oracle.com/technetwork/java/javase/downloads/index-jsp-138363.html

Configure the 'PATH' system variable under environment variables

Go to Control Panel > System > Advanced System Settings, it will open the System Properties window.
Click on the "Environment Variables" button.
Click on the "View" button under User Variables.
Give the variable name as 'JAVA_HOME'.
The variable value will be your JDK path where you installed JAVA.

Select path variable under system variable and click on the "Edit" button.

Add a new path as mentioned below and click the "OK" button.

SonarQube Server Installation

    Download SonarQube from https://www.sonarqube.org/downloads/
    Extract it in one of your local drives like D:\sonarqube-7.6.
    Run the Command Prompt as Administrator. Go to the extracted path and run StartSonar.bat.

    SonarQube server is started locally.
    In order to verify the same, browse http://localhost:9000 in the browser and you will be able to see the landing page of SonarQube.
    Default UserName and Password is admin,

    Creating a Project

      Click on the project in the main menu. Click on + button mentioned on the right side of the page and click on "Create New Project".

      Provide the project key and display name.
      Click on the "Set Up" button.
      SonarQube Configuration For .NET Core Web API 
      Click on the "Generate" button to generate the token.

      A token is generated and you can make a note of that for future use.

      Click on the recently created project and click on "Overview".
      Provide the recently created token.
      In the next step, select your project language and click on "Download" to download the Scanner for MSBuild.

      Evaluate an Application by SonarQube

        Extract it in one of your local drives like D:\sonar-scanner.
        Run the Command Prompt as Administrator.
        Now, here, I am assuming that you have your application, i.e., Web API in .NET Core is ready. If you don't have and you want to test with SonarQube, then you can download any .NET Core Web API project from https://github.com/akshayblevel?tab=repositories
        Execute the below command sequentially.
        dotnet E:\sonar-scanner\SonarScanner.MSBuild.dll begin /k:"{token-created while creating project}"
        dotnet build D:\Akki\POC\DemoWebAPI\DemoWebAPI.sln
        dotnet E:\sonar-scanner\SonarScanner.MSBuild.dll end

        Check the evaluation result

        Run the SonarQube page http://localhost:9000 
        Click on your project and you will be able to see the code analysis result on the page like the number of bugs, vulnerabilities, code smells, code duplication etc.

        Click on each link and you will get all the details with file and line numbers, it will also suggest the solution to resolve that.

        Automate Git Commands Across Repos Using Batch Scripts

          Writing Scripts to Apply Commands Across Repositories I store all of my local repositories in a particular directory. I wrote these scripts to automate one or more git commands to run on each repository within that directory. It could also be used to do a general clean-up before committing anything to your repository. Here are two ways to do it. Method 1: Use this when you want to store commands in a single file to be executed in sequence for every repo in your directory. 1 @echo off 2 ​ 3 for /d %%i in (%cd%\*) do ( 4 echo ************************************************************************* 5 ​ 6 echo "%%i" 7 cd "%%i" 8 ​ 9 echo ----------------------------------------- 10 echo status 11 git status 12 echo ----------------------------------------- 13 ​ 14 echo ************************************************************************* 15 ) 16 ​ 17 cd .. 18 ​ The script is simple: It’s composed of a single for loop.
