Setting Up Java 8 CI with Ant, Jenkins, SonarQube, and JaCoCo

Technical environment: CI is essential for security‑driven projects; the proof‑of‑concept demonstrates that Java 8, NetBeans 8.0, Ant, JUnit 4, JaCoCo 0.7.1, Jenkins and Sonar 4.2 can work together.

Java 8 & NetBeans & Ant: the tutorial builds a modular multi‑layer application using Ant (Maven can also be used) and describes the module suite structure.

JUnit 4 & JaCoCo: unit tests are written with JUnit 4 and code coverage is collected with JaCoCo, which fully supports Java 8.

Jenkins & Sonar: Jenkins serves as the CI engine, integrating the above tools; SonarQube performs quality analysis and is compatible with Java 8. The Sonar Ant task is added via a small library or Maven plugin.

Project configuration steps: install Java 8, create a module suite with classes and JUnit tests, commit to version control, set up JaCoCo and Sonar Ant task folders, and add the following Ant build file (sonar‑jacoco‑module.xml):

Builds the module suite otherSuite.
Some tests failed; see details above.

A second Ant file (sonar‑jacoco‑suite.xml) defines the SonarQube configuration at the suite level, including database connection properties, project keys, source, binary and test paths, and the tasks to merge JaCoCo reports and run Sonar analysis.

Builds the module suite otherSuite.

Additional steps include installing Jenkins plugins (JaCoCo, Mercurial/Subversion, Sonar), configuring the Jenkins system settings, creating a freestyle job that invokes the Ant build files, and adding a post‑build action to record JaCoCo coverage. Finally, the SonarQube database is prepared with a GRANT statement and the sonar.properties file is edited to enable MySQL.
