Eclipse(Photon)找不到我的maven依赖jar

我正在尝试从maven repo导入一个库。但我错在说 "The import org cannot be resolved" ,截图如下:

还有,我的 pom.xml 看起来像:

<project xmlns="http://maven.apache.org/POM/4.0.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

        </dependency>
    </dependencies>
</project>
