## maven中mybatis-generator自定义插件，无法实例化的问题 ##

1.  问题描述

Execution default-cli of goal org.mybatis.generator:mybatis-generator-maven-plugin:1.3.6:generate failed: Cannot instantiate object of type [你的自定义插件路径]

1.  问题解决

需要把对应的插件类打包成jar，然后再把打包好的jar安装到本地maven库中，添加到插件的依赖中：

1.  maven将jar包安装到本地仓库的方法：

mvn install:install-file -Dfile=【jar包的路径】 -DgroupId=【你的groupid】 -DartifactId=【你的artifactid】 -Dversion=【你的版本号】 -Dpackaging=jar
    
    mvn install:install-file -Dfile=E://MavenRep//mybatis_generator_plugs.jar  -DgroupId=cn.zanezz -DartifactId=commnetgenerator -Dversion=1.0.0 -Dpackaging=jar
    
    该依赖要放到插件的依赖中，否则会出现同样的问题
    <dependency>
            <groupId>cn.zanezz</groupId>
            <artifactId>commnetgenerator</artifactId>
              <version>1.0.0</version>
      </dependency>

或者直接在插件如下代码

<plugin>
                    <groupId>org.mybatis.generator</groupId>
                    <artifactId>mybatis-generator-maven-plugin</artifactId>
