Features of maven build resources

function of build resoures

When maven is packaged, the default resource files are all under src / main / resources, so only the resource files in this directory will be packaged.
If you need to package resource files from other directories, you need to specify the directories through resources.

This also reflects the idea that maven default is greater than the configuration

Distribution method of packaging other directory resource files

1. Use build-helper-maven-plugin

    <build>  
    ...  
    </plugins>  
        ...  
        <!--  
        利用此plugin，把源代码中的xml文件，  
        打包到相应位置，这里主要是为了打包Mybatis的mapper.xml文件   
        -->  
        <plugin>  
            <groupId>org.codehaus.mojo</groupId>  
            <artifactId>build-helper-maven-plugin</artifactId>  
            <version>1.8</version>  
            <executions>  
                <execution>  
                    <id>add-resource</id>  
                    <phase>generate-resources</phase>  
                    <goals>  
                        <goal>add-resource</goal>  
                    </goals>  
                    <configuration>  
                        <resources>  
                            <resource>  
                                <directory>src/main/java</directory>  
                                <includes>  
                                    <include>**/*.xml</include>  
                                </includes>  
                            </resource>  
                        </resources>  
                    </configuration>  
                </execution>  
            </executions>

    ...  
</build>
