TP #2 : Pipelines gitlab

Setting up a GitLab Project

Difficulty: Easy

Create a .gitlab-ci.yml file in the project’s root directory that contains:

.gitlab-ci.yml

stages:
  - prepare

image: openjdk:17-slim

variables:
  LIB_FOLDER: "lib"
  SRC_FOLDER: "src"
  TEST_FOLDER: "tests"
  BUILD_FOLDER: "out"
  JUNIT_REMOTE: "https://repo1.maven.org/maven2/org/junit/platform/junit-platform-console-standalone/1.9.3/junit-platform-console-standalone-1.9.3.jar"
  JUNIT_LOCAL: "$LIB_FOLDER/"junit-platform-console-standalone.jar"
  JACOCO_REMOTE: "https://search.maven.org/remotecontent?filepath=org/jacoco/jacoco/0.8.13/jacoco-0.8.13.zip"
  JACOCO_LOCAL_ZIP: $LIB_FOLDER/"jacoco.zip"

before_script:
  - apt-get update && apt-get install -y curl unzip
  - mkdir -p lib
  - curl $JUNIT_REMOTE -o $JUNIT_LOCAL
  - curl -L $JACOCO_REMOTE -o $JACOCO_LOCAL_ZIP
  - mkdir -p lib/jacoco
  - unzip $JACOCO_LOCAL_ZIP -d $LIB_FOLDER/jacoco

print-info:
  stage: prepare
  script:
    - echo "Using Java version:"
    - java -version

This file means that there is a single stage in the pipeline (prepare). Since gitlab launches virtual machines to build your work, an image is needed. We choose to use a recent version of java (opendjdk:17-slim). Some variables are defined in order to prevent some copy/paste errors and the before_script stage is used to install some dependencies (in our case junit and jacoco). Then a dummy job print-info is defined to print some information. And this job is triggered by the prepare stage. You can see that the script section of a job is a sequence of commands that will be executed.

Add the .gitlab-ci.yml file to your repository and commit and push your changes.
On the gitlab website, you should be able to see the pipeline being run and once finished a green checkmark is displayed.
Add a second job to the prepare stage that displays the content of your lib folder (it might be useful for debugging purpose to be sure that you have all the needed jar files).
Commit and push your changes

Building your project

Difficulty: Rx

Warning

From the rest of this practical, you should reuse and ADAPT compilation commands that have been used in the previous practical (TP1)

Add a build stage and a compile job that will compile your source files in the out/classes folder.
Commit your work and see if the pipeline is triggered and successful on gitlab.

Testing your project

Difficulty: Rx

Add a build-tests stage and a compile-tests job that will compile you test files in the out/test-classes folder
Commit your work and see if the pipeline is triggered and successful on gitlab.

Danger

It should generate an error because the out/classes/*.class are not found.

Create an artifact¹ in your jobs (compile and compile-tests) for the out folder with:

artifacts-example.yml

artifacts:
  paths:
    - out/
  expire_in: 1 week

Running the tests

Difficulty: Rx

Add a test stage and a run-tests job that will run the tests
Commit your work and see if the pipeline is triggered and successful on gitlab.
Do not forget to add the necessary artifacts in your job.

Getting the code coverage

Difficulty: Rx

Add a coverage stage and a jacoco job that will run the tests
Commit your work and see if the pipeline is triggered and successful on gitlab.
Do not forget to add the necessary artifacts in your job.

Do the report

Difficulty: Hard

Add a report stage and a build-report job that will use jacoco to generate the report based on the jacoco.exec file from the jacoco job.

Info

xml or csv report are better options than html because they are easier to parse and to extract data.

(Bonus) Extract the code coverage

In the reportstage, add a job that will extract the code coverage from the report. You could use any tool you want (grep, xmllint…)

Wrapping up

Create a README.md file that includes the pipeline status and the code coverage badges (see https://docs.gitlab.com/ee/user/project/badges.html).

Checkstyle

Download checkstyle…
… and place it in your lib folder
Create a checkstyle.xml to define the rules your source code should follow (you can use the file detailed at the end of this page)
Run checkstyle on your source files with the command:

java -jar lib/checkstyle-11.1.0-all.jar -c checkstyle.xml src/

Be sure that there are no errors
Create a code smell in Calculator.java by modifying the add method with

int c = a, d = b;
return c + d;

Rerun checkstyle and see that a code smell [MultipleVariableDeclarations] is issued.
Revert the file Calculator.java

Adding Stages

Define a lint stage in the .gitlab-ci.yml file before the build stage.
Add a checkstyle job that will use checkstyle to check your source code.

Checking for duplicates

At the root of your $HOME folder, download pmd with the command

curl -L https://github.com/pmd/pmd/releases/download/pmd_releases%2F7.17.0/pmd-dist-7.17.0-bin.zip -o pmd.zip

Extract the zip file
In you repository run the cpd commande with

~/pmd/bin/pmd cpd --minimum-tokens 80 --dir src/

Ensure that there are no duplicates
Create some duplicates in your code and ensure that they are detected with cpd

Adding a cpd job

Add a check-duplicates job that will use cpd to check your source code.

Code quality with SonarQube

Go to https://sonarqube.polytech-lille.fr/projects

and create a new project and get the token.

Download sonar-scanner on your machine
In your root folder, create a file named sonar-project.properties containing:

# Project metadata
sonar.projectKey=Your Projet
sonar.projectName=Your Project Name
sonar.projectVersion=1.0
sonar.login=Your Token
sonar.host.url=http://cadmium.polytech-lille.org:9000

# Project base directory (if different from root)
sonar.projectBaseDir=.

# Source files
sonar.sources=src

# Binaries directory (build output)
sonar.java.binaries=out/**

# Test files (optional)
sonar.tests=tests

# Exclude specific folders
sonar.exclusions=**/lib/**

# Language and encoding
sonar.language=java
sonar.sourceEncoding=UTF-8

In you project folder, launch sonar-scanner. Once finished get the report at https://sonarqube.polytech-lille.fr/projects
