Configuração para Code Coverage usando Maven, Jenkins e um dos seguintes plugins para gerar a cobertura de código: OpenClover, Cobertura e JaCoCo.

OpenClover

Maven - pom.xml

<plugin>
    <groupId>org.openclover</groupId>
    <artifactId>clover-maven-plugin</artifactId>
    <version>4.2.0</version>
    <configuration>
        <jdk>1.8</jdk>
        <instrumentLambda>block</instrumentLambda>
        <showInnerFunctions>true</showInnerFunctions>
        <showLambdaFunctions>true</showLambdaFunctions>
        <includesTestSourceRoots>true</includesTestSourceRoots>
        <setTestFailureIgnore>true</setTestFailureIgnore>
        <generateHistorical>true</generateHistorical>
        <historyDir>${user.home}/.clover-history/${project.groupId}-${project.artifactId}</historyDir>
    </configuration>
</plugin>

Executar

mvn clean clover:setup package clover:aggregate clover:save-history clover:clover

Artefatos gerados

• target/clover
• target/site/clover/index.html

Jenkins

Plugin

https://wiki.jenkins.io/display/JENKINS/Clover+Plugin

Configuração

• Goals do maven conforme acima
• No Post-build Actions adicionar Publish OpenClover coverage report

Observação:

Para acessar o relatório do Clover disponibilizado por dentro do Jenkins é necessário configurar o Content Security Policy. Para isso executar no Script Console do Jenkins:

System.clearProperty("hudson.model.DirectoryBrowserSupport.CSP");

System.setProperty("hudson.model.DirectoryBrowserSupport.CSP", "default-src 'self'; script-src * 'unsafe-inline'; img-src * 'self' data:; style-src * 'unsafe-inline'; font-src *");

println(System.getProperty("hudson.model.DirectoryBrowserSupport.CSP"))

Se reiniciar o Jenkins as configurações acima são perdidas. Para deixar persistente é necessário configurar na inicialização. Mais detalhes abaixo:

            </excludes>
        </instrumentation>
    </configuration>
    <dependencies>
        <dependency> <!-- se houver problema com ASM -->
            <groupId>org.ow2.asm</groupId>
            <artifactId>asm</artifactId>
            <version>6.0</version>
          </dependency>
    </dependencies>
</plugin>

Executar
