1. Overview

Enforce and report code quality with:

  1. Checkstyle with Google Java coding standards (maven-checkstyle-plugin)
  2. CodeNarc (codenarc-maven-plugin)
  3. Duplicate-Finder (duplicate-finder-maven-plugin)
  4. Enforcer (maven-enforcer-plugin)
  5. FindBugs (findbugs-maven-plugin)
  6. fmt-maven-plugin formats your code using google-java-format, which follows Google's code styleguide (fmt-maven-plugin)
  7. JDepend (jdepend-maven-plugin)
  8. JUnit (junit5 with junit4 backwards compatibility)
  9. JaCoCo (jacoco-maven-plugin)
  10. PMD (maven-pmd-plugin)
  11. Report site generation (maven-site-plugin)

and more with this Maven POM.


The purpose of the project is to use the Maven Site Plugin to:

  1. Use the Maven Site Plugin to generate meaningful test and quality reporting artifacts
  2. Enforce test coverage thresholds and code standards
  3. Prevent source code that does not conform to standards from being merged into master.

2. Prerequisite software

4. Usage

4.1. Run unit tests, evaluate complexity, and check coverage

$ mvn test verify

4.2. Generate site files

To build the Maven reports site, open a Terminal and run:

$ mvn site

Then open maven-code-quality-pom/target/site/index.html in a Web browser.

4.3. Run quality checks

  • 4.3.1. mvn fmt:check

    Formats all src/ and test/ Java code according to the Google Java style guide.

    ℹ️ mvn fmt:format runs with every build.

  • 4.3.2. mvn enforcer:display-info

    Executes the defined enforcer-rules once per module and displays the current platform information

  • 4.3.3. mvn site

    Generates the site for a single project.

  • 4.3.4. mvn checkstyle:check

    Performs Checkstyle analysis and outputs violations or a count of violations to the console, potentially failing the build.

  • 4.3.5. mvn duplicate-finder:check

    Finds duplicate classes/resources on the classpath.

  • 4.3.6. mvn findbugs:check

    Identify defect (bug) patterns in your Java source code.

  • 4.3.7. mvn pmd:check

    Fail the build if there were any PMD violations in the source code.

  • 4.3.8. mvn pmd:cpd-check

    Fail the build if there were any CPD violations in the source code.

4.3. Export reports to SonarCloud.io
