maven 编译与此同时复制指定文件以及文件夹

maven 编译同时复制指定文件以及文件夹
现有项目test，我想在maven编译时同时拷贝另一文件到编译母目录，比如在执行mavn clean compile 时，把c盘下的abc.xml拷贝到编译目录target下，同时把c盘下的abc文件夹下所有内容拷贝到项目指定文件夹下，比如target下的abc文件夹,请问怎么做？
我试着在pom.xml中添加

<plugin>
                                <artifactId>maven-antrun-plugin</artifactId>
                                <executions>
                                        <execution>
                                                <id>gen-webadmin</id>
                                                <phase>compile</phase>
                                                <configuration>
                                                        <tasks>
                                                                <copy todir="${basedir}/target/build/plugin_update/plugin"
                                                                        file="${basedir}/plugin.xml" />                                     
                                                        </tasks>
                                                </configuration>
