mybatis-generator生成数据对象

Question

最开始的报错：

Failed to execute goal org.mybatis.generator:mybatis-generator-maven-plugin:1.3.2:generate (default-cli) on project mmall: Execution default-cli of goal org.mybatis.generator:mybatis-generator-maven-plugin:1.3.2:generate failed: Cannot resolve classpath entry: /g/Program/Java/JAVA_workSpace/mysql-connector-java-5.1.6-bin.jar -> [Help 1]

将classPathEntry location改为绝对路径之后报错：

Failed to execute goal org.mybatis.generator:mybatis-generator-maven-plugin:1.3.2:generate (default-cli) on project mmall: Access denied for user 'root'@'113.250.152.4' (using password: YES) ->

各种尝试均无果。。。。希望各位能帮忙解决一下。

PS：在课程4.9中 我在git bash中无法使用 ll 命令（command not found）,所以无法查看我是否下载了mysql-connector-java-5.1.6-bin.jar  于是自己去下载了一个

额。。成 功 了？？！！该怎么说？迷之兼容性？？这个问题看了好多帖子。。也试了菠萝的pom.xml文件，每次试也rebuild。。还是不行。。之后尝试新窗口直接导入老师的源代码，点自动生成dao层，尝试让它报重复生成表的接口的错误，不负所望，出现期望的错误，用源码的datasource.propertise和generatorConfig.xml替代自己创建的mmall_learning项目中相应的文件，竟然OK了

我改成菠萝的pom.xml文件。。。但还是 Cannot resolve classpath entry: E:/IdeaProjects/mmall_learning/src/main/tool/mysql-connector-java-5.1.6-bin.jar"。。

你好，同学 路径不对吧？你是linux还是windows，windows的话盘符呢？

g:/这样写路径哟。

另外这里还提示了权限问题检查自己的账号密码是否正确。mysql是否开通了外部访问权限。

这个bin.jar包在项目的tools文件夹下是有的。同学可以看看哟。
