- 文中测试例子均采用JHotDraw7源码,官网关于 JHotDraw的检测结果:http://pmd.sourceforge.net/reports/jhotdraw_JHotDraw.html
- 下载地址:https://sourceforge.net/projects/pmd/files/pmd/5.1.0/
- 安装:解压到任意目录。
3. 使用方法:
3.1 使用命令行:(Windows下)
命令行进入PMD安装目录,bin文件夹,执行命令:
基本命令:pmd -d C:\Users\lsp\Desktop\svn\jhotdraw7\src -f html -R rulesets/java/unusedcode.xml
其中 C:\Users\lsp\Desktop\svn\jhotdraw7\src为所需要分析源码绝对路径,可以是文件夹也可以是单个文件。
-R 表示的采用的检测规则。 此规则都存在于
Rulesets下有多种语言的规则,Java下又包含多种规则,在命令行每次只能检测单个规则(暂时未发现多条规则应用于一次检测),也可以自定义规则,具体怎么定义参见官网。
-f 设置检测结果输出格式,html, xml,text, csv,
该工具默认命令行检测结果输出到控制台,可以通过-r参数导出检测结果:如D:\Program Files\pmd-bin-5.1.0\bin>pmd -d C:\Users\lsp\Desktop\svn\jhotdraw7\src -f html -r D:\pmdreport\PMDoutput.html -R rulesets/java/unusedcode.xml

3.2 Ant
在项目路径下build.xml文件中加入:
D:\Program Files\pmd-bin-5.1.0\lib为pmd安装路径下的lib
C:\Users\lsp\Desktop\svn\jhotdraw7\src\源码路径
D:\pmdreport\pmd_report.xml分析结果文件
<formatter type="xml" toFile="D:\pmdreport\pmd_report.xml"/> 格式化输出xml
<formatter type="net.sourceforge.pmd.renderers.HTMLRenderer" toFile="D:\pmdreport\foo.html"/> 格式化输出HTML
<path id="pmd.classpath">
<pathelement location="${build}"/>
<fileset dir="D:\Program Files\pmd-bin-5.1.0\lib">
<include name="*.jar"/>
</fileset>
</path>
<taskdef name="pmd" classname="net.sourceforge.pmd.ant.PMDTask" classpathref="pmd.classpath"/>
<target name="pmd">
<pmd rulesetfiles="rulesets/java/imports.xml,java-unusedcode">
<formatter type="xml" toFile="D:\pmdreport\pmd_report.xml"/>
<fileset dir="C:\Users\lsp\Desktop\svn\jhotdraw7\src\">
<include name="**/*.java"/>
</fileset>
</pmd>
</target>
3.3 Maven
使用maven插件检测较为简单,只需在pom.xml文件中加入:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-pmd-plugin</artifactId>
</plugin>
执行mvn pmd:pmd
即可在target文件夹下看到以下文件:
即违反规则的报告文件,每个规则对应一个xml文件。也可以配置规则。
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-pmd-plugin</artifactId>
<configuration>
<rulesets>
<ruleset>/rulesets/braces.xml</ruleset>
<ruleset>/rulesets/naming.xml</ruleset>
</rulesets>
</configuration>
</plugin>
3.4 Eclipse Ide
安装网址: http://sourceforge.net/projects/pmd/files/pmd-eclipse/update-site/
安装完右键项目或文件:选择PMD->check code即可使用PMD工具检查代码。
选择PMD-->Find suspect cut and paste。检查结果会放在reports目录下
