ClassNotFoundException: MyBatis3Simple

Question

当我使用mybatis生成器从mysql中自动生成映射器xml和模型时，我得到了以下错误：

[INFO] --- mybatis-generator-maven-plugin:1.3.0:generate (default-cli) @ loanmanager ---
java.lang.RuntimeException: Cannot instantiate object of type MyBatis3Simple
    at org.mybatis.generator.internal.ObjectFactory.createInternalObject(ObjectFactory.java:136) ...
Caused by: java.lang.ClassNotFoundException: MyBatis3Simple
    at org.codehaus.plexus.classworlds.strategy.SelfFirstStrategy.loadClass(SelfFirstStrategy.java:50)

生成器配置为：

**<generatorConfiguration>
    <!--<properties resource="">-->
    <!--</properties>-->

    <!-- 配置成你本地的mysql-connector-java jar -->
    <classPathEntry
            location="/Users/shenbin/.m2/repository/mysql/mysql-connector-java/5.1.40/mysql-connector-java-5.1.40.jar" />
<context id="baseTradeTables" targetRuntime="MyBatis3Simple" defaultModelType="flat">
<property name="beginningDelimiter" value="`"/>
        <property name="endingDelimiter" value="`"/>

        ...
</context>
</generatorConfiguration>**

pom.xml为：

<build>
        <plugins>
            <plugin>
                <groupId>org.mybatis.generator</groupId>
                <artifactId>mybatis-generator-maven-plugin</artifactId>
                <version>1.3.0</version>
            </plugin>
        </plugins>
    </build>

但是如果我使用MyBatis3，它可以正常运行。

您使用的是1.3.0，但MyBatis3Simple是从1.3.2版本开始添加的。see this for detail
