首先，研发写的代码里要有单元测试相关的桩内容。
1.需要下载可用的jacoco.jar包配置到build.xml中
2.jenkins配置：
sonar.projectKey=${JOB_NAME}
sonar.projectName=$JOB_NAME
sonar.projectVersion=$SVN_REVISION
sonar.sources=.
sonar.language=java
sonar.sourceEncoding=UTF-8
sonar.dynamicAnalysis=reuseReports
sonar.core.codeCoveragePlugin=jacoco
sonar.surefire.reportsPath=${WORKSPACE}/billtrunk/target/junit
sonar.java.binaries=${WORKSPACE}/billtrunk/bin/classes
sonar.jacoco.reportPath=${WORKSPACE}/billtrunk/target/sonar/jacoco.exec
sonar.junit.reportPaths=${WORKSPACE}/billtrunk/target/junit
sonar.jacoco.itReportPath=${WORKSPACE}/billtrunk/target/ITCoverageReport/jacocoIT.exec
3.build.xml样本
<?xml version="1.0" encoding="UTF-8"?>
<project name="Simple Java Project analyzed with the Sonar Ant Task" default="all" basedir="." xmlns:jacoco="antlib:org.jacoco.ant" xmlns:sonar="antlib:org.sonar.ant" xmlns:ivy="antlib:org.apache.ivy.ant">

</jacoco:report>
</target>
<!-- ========= The main target "all" ========= -->
<target name="all" depends="clean,resolve,compile,it coverage report" />
</project>
4.单元测试要显示在sonarqube中，需要在web端配置
5.可以在设计，链接中加入详情
可以tomcat的conf/server.xml中配置链接 <host>标签内加上访问url
<Context path="/coverage" docBase="/opt/jenkins/workspace/UNIT_TEST_srpbase-common/billtrunk/target/report" debug="0" privileged="true">
</Context>
<Context path="/junit" docBase="/opt/jenkins/workspace/UNIT_TEST_srpbase-common/billtrunk/target/junit" debug="0" privileged="true">
</Context>
