在单独运行web模块之前，您需要在父模块中

mvn clean install

将另一个模块安装到本地回购

或者，您可以在web模块中

mvn clean install-am

，以便它构建依赖的模块

请在服务模块中将包装更改为jar，或者将其删除，默认包装为jar

<packaging>jar</packaging>
<name>croz-service</name>

jar
克罗兹服务

转到包含项目pom文件的文件夹。然后获取cmd并运行

mvn clean install

如果失败，请在删除目标文件夹后重试

应用程序的类路径中缺少类hr.croz.bspoljaric.service.AddressService。您需要修复创建war的方式，并确保所有必要的jar文件都存储在其WEB-INF/lib目录中。重要的是你的pom文件在这里。不是密码。谢谢回复。我显然遗漏了一些东西，因为我在WebPOM文件中声明了对服务的依赖。这些是我的pom文件：1。网站：；2.家长：；3.服务：嘿，我已经运行了maven安装，一切都很顺利，但我仍然得到了错误。
