ant+sonar+jacoco代码质量代码覆盖率扫描

使用ant构建的java web项目如何做sonar代码质量扫描？
以下就是实际遇到并成功使用的案例
一、做sonar扫描的准备工作
    1.给web项目增加build.xml构建脚本。
    2.下载jar包：jacocoant.jar；sonar-ant-task-2.2.jar
    3.搭建一个sonar服务器
二、在build.xml中编写jacoco和sonar的脚本

　　案例的build.xml脚本

                        <!-- Update the following line, or put the "sonar-ant-task-*.jar" file in your "$HOME/.ant/lib" folder -->
                        <classpath path="${basedir}/third/sonar-ant-task-2.2.jar" />
                </taskdef>

                <!-- Execute Sonar -->
                <sonar:sonar />
        </target>

        <!-- ========= The main target "all" ========= -->
        <target name="all" depends="clean,compile,test,sonar" />

</project>

    1.因为ant中没有像maven那样天然集成sonar，所以在脚本中需要加入很多sonar需要的属性。
    2.需要一个target任务执行jacoco:coverage并生成代码覆盖率文件jacoco.exec；这里注意jacoco.exec是在<jacoco:coverage destfile="${basedir}/jacoco.exec">指定，如果没有destfile属性则默认在项目根目录生成名为jacoco.exec文件。这个生成的文件要和<property name="sonar.jacoco.reportPath" value="jacoco.exec" />对应，这步是把jacoco.exec交给sonar去解析。

        <jacoco:coverage>
             <junit fork="true" forkmode="once" printsummary="on" showoutput="true">
                <formatter type="xml" usefile="true"/>
                 <classpath>  
                  <fileset dir="${lib.dir}" includes="**/*.jar"/>  
                  <pathelement path="${classes.dir}"/>  
                </classpath>
                <batchtest todir="${reports.junit.xml.dir}">
                 <fileset dir="${classes.dir}">
                    <include name="**/*Test*.*" />
                 </fileset>
                </batchtest>
             </junit>
        </jacoco:coverage>    

   

　　3.这步非必须；如果要生成jacoco报表还可以添加一个<jacoco:report>，可以生成html、xml、csv类型的报表。

            <jacoco:report>
                <executiondata>
                    <file file="jacoco.exec" />
                </executiondata>
                <structure name="ma project coverage report">
                    <classfiles>
                        <fileset dir="${basedir}/target/classes" />
                    </classfiles>
                    <sourcefiles encoding="UTF-8">
                        <fileset dir="${src.dir}" />
                    </sourcefiles>
                </structure>
                <html destdir="${basedir}/target/report" />
                <csv destfile="${basedir}/target/report/report.csv" />
                <xml destfile="${basedir}/target/report/report.xml" />
            </jacoco:report>        

　　4、代码覆盖率做完了就可以做sonar代码质量扫描了。

        <target name="sonar" depends="compile">
            <taskdef uri="antlib:org.sonar.ant" resource="org/sonar/ant/antlib.xml">
                    <classpath path="${basedir}/third/sonar-ant-task-2.2.jar" />
            </taskdef>

            <!-- 执行 Sonar -->
            <sonar:sonar />
    </target>

三、运行这个build脚本，成功后就可以去sonar服务器查看结果了。
