执行Maven Install打包的时候，出现以下错误信息：

经过检查才发现原来是<encoding>utf-8</encoding>标签放错位置了，应该放在<configuration>标签里面：

            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>3.0</version>
                <configuration>
                    <encoding>utf-8</encoding>
                    <source>1.8</source>
                    <target>1.8</target>
                </configuration>
            </plugin>
