在本文中，我们将向您展示如何使用[Maven PMD插件][Maven PMD]来分析Java代码。

*PS PMD需要Java 1.7*

## 1. Maven PMD插件 ##

在`reporting`标记中定义`maven-pmd-plugin` ，以便`mvn site`将生成PMD报告。

pom.xml

<reporting>
            <plugins>
          
                <plugin>
                    <groupId>org.apache.maven.plugins</groupId>
                    <artifactId>maven-pmd-plugin</artifactId>
                    <version>3.11.0</version>
                </plugin>
    
            </plugins>
        </reporting>

## 2. Java代码 ##

一个简单的Java代码。 我们将使用Maven PMD插件来分析此代码并在报告中显示问题。

package com.mkyong.examples;
    
    public class StaticCodeExample {
    
        //Unused field
        private int abc;
    
        private String ip = "127.0.0.1";
    
        public void test() {
    
            String[] field = {"a", "b", "c", "s", "e"};
    
            String s = "";
            for (int i = 0; i < field.length; ++i) {
                s = s + field[i];
            }
    
            System.out.println(ip);
    
        }
    
    }

## 3. Maven网站 ##

`mvn compile site`将为Java项目生成Maven站点，将生成PMD报告并将其自动集成到Maven站点中。

$ mvn compile site

## 4. PMD报告 ##

在`target/site/pmd.html`查看报告
