Question

我用Maven创建了dyamic web项目。我在我的pom.xml中使用了这个（https://github.com/Codearte/jfairy）假数据生成器插件作为maven，如下所示：

<dependency>
    <groupId>io.codearte.jfairy</groupId>
    <artifactId>jfairy</artifactId>
    <version>0.5.3</version>
</dependency>

但我得到的错误如下：

所以建议我。

Eclipse maven集成效果不佳。您可以转到项目目录并运行此命令：

mvn eclipse:clean
mvn eclipse:eclipse
mvn install

换句话说，每次更改pom.xml时，最好使用

mvn eclipse:eclipse

壳牌中的
