【问题描述】：
我正在使用 Eclipse 开发 Web 应用程序，并使用 maven 原型生成项目。
当我启用maven依赖管理时，Eclipse在pom文件中标记了一些错误，这个错误是：
Multiple annotations found at this line:

我的 pom 文件如下：

有什么想法吗？
【问题讨论】：
-
错误提示 maven 无法访问远程存储库。 “mvn clean package”可以在控制台上运行吗？
-
我使用 Windows 的同事也有同样的问题。我正在使用 ubuntu，相同版本的 maven 和 eclipse，相同的项目……一切正常……
-
在我的情况下，它只用 mvn clean install -U 解决了
-
如果所需插件的版本与 maven 存储库中的版本不同，可能会发生这种情况，例如在恢复旧项目时，其中一个 maven 插件的版本较早.如果是这种情况，更新到已安装插件的正确版本号，将修复它。
