mybatis-plus 错误java.lang.NoClassDefFoundError: org/apache/velocity/context/Context

错误

使用mybatis-plus自动生成文件的时候，报下面的错误：

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/velocity/context/Context
    at com.baomidou.mybatisplus.generator.AutoGenerator.execute(AutoGenerator.java:100)
    at com.layuicms.erp.utils.CodeGenerator.main(CodeGenerator.java:101)

    at java.lang.ClassLoader.loadClass(ClassLoader.java:357)
    ... 2 more

Process finished with exit code 1

原因是缺少了依赖

解决方案

pom.xml文件当中加入velocity的依赖

<!-- 模板引擎 -->
    <dependency>
        <groupId>org.apache.velocity</groupId>
        <artifactId>velocity-engine-core</artifactId>
        <version>2.0</version>
    </dependency>
