<build>
        <resources>
            <resource>
                <directory>src/main/java</directory>
                <includes>
                    <include>**/*.xml</include>
                </includes>
            </resource>
            <!-- 可不写下边的部分 -->
            <resource>
                <directory>src/main/resources</directory>
                <includes>
                    <include>*.xml</include>
                    <include>*.properties</include>
                </includes>
            </resource>
        </resources>
    </build>

After adding, remember to rewrite and load the pom file. If it still reports an error, check the compiled version and project structure version. After modifying, click Apply and then OK
