本地jar使用Maven打包

复制jar包到resources下

IDEA\Project Setting\Libraries添加jar包

pom.xml加入此dependency

        <dependency>
            <groupId>org.opencv</groupId>
            <artifactId>opencv</artifactId>
            <version>3.3.0</version>
            <scope>system</scope>
            <systemPath>${project.basedir}/src/main/resources/opencv-330.jar</systemPath>
        </dependency>

clean && package
