m2eclipse错误

Question

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会在pom文件中标记一些错误,这个错误是:

我的pom文件如下:

<project xmlns="http://maven.apache.org/POM/4.0.0"                 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

 </project>

任何的想法？

Answer 1

Eclipse 3.7.2(Indigo)和maven 3.0.4也遇到了同样的问题.

对我来说,这个问题是由缺少造成maven-resources-plugin-2.4.3.jar的{user.home}\.m2\repository\org\apache\maven\plugins\maven-resources-plugin\2.4.3文件夹中.(不知道为什么maven没有更新它)

解:

1.)为pom.xml添加依赖项

<dependency>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-resources-plugin</artifactId>
    <version>2.4.3</version>
</dependency>

2.)mvn install从Eclipse或命令行运行

3.)在eclipse中刷新项目(F5)

4.)Maven > Update Project Configuration...在项目上运行(右键单击)

JAR文件下载到本地存储库,WS中没有错误.

Answer 2

Eclipse 3.7.2(Indigo)和maven 3.0.4也遇到了同样的问题.

Eclipse没有拿起我的maven设置,所以这就是我解决问题的方法:

1. 窗口 - 首选项 - Maven - 安装

   • 添加(Maven 3.0.4而不是使用嵌入式)
   • 单击"应用并确定"

2. 项目中的 Maven> 更新项目配置 ...(右键单击)

3. 关闭 Eclipse

4. 运行 mvn install命令行.

5. 打开 Eclipse

这些步骤对我有用,但问题并不一致.我只在一台电脑上遇到问题.

Answer 3

只需转到您的用户文件夹,其中有一个".m2"文件夹,打开它并删除文件夹"repository".转到eclipse,清理你的项目,然后右击 - > Maven-> Update Project ..你准备好了.

Answer 4

我通过mvn -U install从命令行运行然后从Eclipse 运行"Maven-> Update Project"来解决这个问题

Answer 5

在这种特殊情况下,解决方案是eclipse的正确代理配置(Window - > Preferences - > Network Connection),该公司拥有严格的安全系统.我会留下这个问题,因为有些答案可以帮助社区.非常感谢您的上述答案.
