在maven的web项目的test的文件执行main方法报错Failed to execute goal org.codehaus.mojo:exec-maven-plugin:3.1.0:exe问题

在pom.xml添加这个插件

<build>
    <plugins>
        <plugin>
            <groupId>org.codehaus.mojo</groupId>
            <artifactId>exec-maven-plugin</artifactId>
            <version>3.1.0</version>
            <executions>
                <execution>
                    <goals>
                        <goal>java</goal>
                    </goals>
                </execution>
            </executions>
            <configuration>
                <classpathScope>test</classpathScope>
            </configuration>
        </plugin>
    </plugins>
</build>
