IDEA使用mybatis-generator插件时遇到的一个bug

2023-12-01

之前使用Windows，在Windows上跑这个项目这个mybatis-generator使用是没有问题的，但是迁移到Mac电脑之后就出问题了。（项目两个电脑上都能正常启动，就只是mybatis-generator插件出了问题）
报错如下：

写了dom4j的jar包没找到
刚开始的pom依赖是这样子的：

于是我在整个依赖中加入了dom4j的依赖，并在mygatis-generator这个plugin中也加入了dom4j的内部依赖。

    <dependencies>
        <dependency>
            <groupId>dom4j</groupId>
            <artifactId>dom4j</artifactId>

        </dependency>
    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
            <!--Demo mybatis generator插件-->
            <plugin>
                <groupId>org.mybatis.generator</groupId>
                <artifactId>mybatis-generator-maven-plugin</artifactId>
                <version>1.3.7</version>
                <configuration>
                    <!--mybatis-generator配置文件的地址-->
                    <configurationFile>
                        mybatis-generator/generatorConfig.xml
                    </configurationFile>
                    <overwrite>true</overwrite>
                    <verbose>true</verbose>
                </configuration>
                <dependencies>
                    <!--内嵌mysql依赖-->
                    <dependency>
                        <groupId>mysql</groupId>
                        <artifactId>mysql-connector-java</artifactId>
                        <version>5.1.46</version>
                    </dependency>
                    <!--内嵌itfsw依赖，逻辑删除的依赖-->
                    <dependency>
                        <groupId>com.itfsw</groupId>
                        <artifactId>mybatis-generator-plugin</artifactId>
                        <version>1.3.8</version>
                    </dependency>

                    <dependency>
                        <groupId>dom4j</groupId>
                        <artifactId>dom4j</artifactId>
                        <version>1.6.1</version>
                    </dependency>
                </dependencies>
            </plugin>
        </plugins>
    </build>
</project>

然后运行，再次报错，又发现是freemarker，没有？？？？为什么原来电脑就不会呢？然后同样再次引入依赖，并且plugin中也内嵌依赖。
最后pom是这样子：

终于问题解决了！！！！可以正常使用mybatis-generator了。
所以上述的ERROR问题，需要在引入所提示的包，并且在plugin中也引入依赖。必须两个依赖都得写，要不然也不会成功！

解决方法：导入错误信息提示的依赖。

但是我还是不知道原因？为什么原来在Windows电脑上使用的时候能够正常使用plugin，而到了Mac电脑就必须多写两个依赖呢？有大神能解答一下否？（狗头）
