maven duplicate finder plugin介绍

maven-duplicate-finder-plugin是一个maven编译过程中检查是否有相同classpath.Classname的情况。

需要在settings.xml中的pluginGroups标签中加入pluginGroup,代码如下:

<pluginGroups>
	<pluginGroup>com.ning.maven.plugins</pluginGroup>
</pluginGroups>

在pom.xml中要加入如下代码:

<build>
	<pluginManagement>
		<plugins>
			
			<plugin>
				<groupId>com.ning.maven.plugins</groupId>
				<artifactId>maven-duplicate-finder-plugin</artifactId>
				<version>1.0.5</version>
				<configuration>
					<failBuildInCaseOfConflict>true</failBuildInCaseOfConflict>
				</configuration>
				<executions>
					<execution>
						<phase>verify</phase>
						<goals>
							<goal>check</goal>
						</goals>
					</execution>
				</executions>
			</plugin>
		</plugins>
	</pluginManagement>
</build>

在命令行进入代码pom.xml文件的目录执行如下命令:
mvn duplicate-finder:check
或者
mvn com.ning.maven.plugins:maven-duplicate-finder-plugin:1.0.5:check
