我在学JAVAEE的时候 总出现Maven的问题

用myeclipes 2018 的时候 创建WEB项目
pom.xml会直接报错，网上查就是MAVEN问题。（自己也试过删除maven仓库没用）
然后用了idea 用maven方式创建项目，输入坐标后还是会报错如下：
Could not find artifact org.mybatis:mybatis:pom:x.x.x in central

现在连创建项目都是问题 。。求大神帮忙解决

是不是配置的setting.xml文件有问题

看问题应该是在仓库或者镜像中没有找到你需要的这个jar包。
那么问题应该是一下两者之一：
1.仓库或者镜像不对，不过这个错误我记得不是这样提示的。
2.这个仓库或者镜像里确实不存在这个jar

你可以尝试最最下面这个setting.xml文件，使用的是aliyun参考。至于mybatis的jar包可以在pom.xml文件中配置：
（官方最新版本是3.5.4，版本无所谓，maven配置方法都是一样）

<dependency>
    <groupId>org.mybatis</groupId>
    <artifactId>mybatis</artifactId>
    <version>3.3.1</version>
</dependency>
