Element ‘plugin‘ cannot have character [children], because the type‘s content type is element-only.

前言

觉得你粘贴格式不对，带了特殊格式，爆红

<plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-surefire-plugin</artifactId>
                <version>2.22.1</version>
                　　<!--版本根据你自己的版本写 -->
                <configuration>
                    <skipTests>true</skipTests>
                </configuration>
            </plugin>

解决

​​参考作者​​ 要么手写，要么学他们粘贴在NotePad++ 转一下

<plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-surefire-plugin</artifactId>
                <version>2.22.1</version>
                <configuration>
                    <skipTests>true</skipTests>
                </configuration>
            </plugin>
