Jenkins+PMD构建自动化静态代码检测

jopen 6年前

前言:软件缺陷是不可避免的,要尽量减少错误并提高软件质量,主要有两在类技术,即缺陷预防和缺陷检测

缺陷预防包括编写更好的设计规范、实施代码审核制度、运行代码静态分析工具、运行单元测试等

PMD是一种开源分析Java代码的工具,通过静态分析获知代码错误,该工具可以做到检查Java代码中是否含有未使用的变量、是否含有空的抓取块、是否含有不必要的对象等等

因此Jenkins+PMD构建自动化静态代码检测是很有必要的


PMD下载地址:http://sourceforge.net/projects/pmd/

下载后解压即可

PMD主要可以通过ant脚本来执行,编写ant的build文件,这里新建的为如buildPMD.xml

    <?xml version="1.0" encoding="UTF-8"?>                <project name="pmd" default="pmd" basedir=".">                     <property environment="env">         <property

</formatter></pmd>        </taskdef></target>                </project>      本文中定义了两个target,分别生成了XML和HTML格式的报告,因为在Jenkins中的分析插件需要用XML格式才能生成视图报告,而XML格式对于团队来说不直观,不宜发送邮件,因此生成两份报告,一份用于Jenkins分析,一份发送邮件用于团队成员直接查看    编写好buildPMD.xml,直接使用ant -f buildPMD.xml即可在CMD命令或Linux shell下执行PMD静态代码检测    在Jenkins中新建个任务,Build项Add build step中选择“Execute Shell”,输入ant -f buildPMD.xml即可    附:pmdrule.xml      [xml] view plaincopy        <?xml version="1.0" encoding="UTF-8"?>
