maven-install-plugin负责将获取的jar包安装到本地仓库

<build>
       <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-install-plugin</artifactId>
                <executions>
                    <execution>
                        <id>install-external</id>
                        <phase>clean</phase>
                        <configuration>
                            <file>${project.basedir}/lib/opencv-341.jar</file>
                            <repositoryLayout>default</repositoryLayout>
                            <groupId>org.opencv</groupId>
                            <artifactId>opencv</artifactId>
                            <version>1.0</version>
                            <packaging>jar</packaging>
                            <generatePom>true</generatePom>
                        </configuration>
                        <goals>
                            <goal>install-file</goal>
                        </goals>
                    </execution>
