当我从命令行（使用farmanager）运行“mvnsite”时，一切都非常好，它将所有必要的jar下载到存储库并执行任务

但是，当我尝试使用m2eclipse插件从eclipse执行相同的操作（mvn站点）时，它会告诉我：

在eclipse中执行项目->清理（同时尝试刷新项目）。当您从命令行编译代码时，有时会在eclipse中引起一些问题，并且必须在eclipse中重新编译代码

使用m2eclipse插件并运行一些程序的所有人，下面是我的提示：

1）使用您自己的maven，而不是在m2eclipse中构建，您可以在m2eclipse首选项中切换到它

2）将存储库位置从C:\Users\current\u user-m2\repository更改为C:\Users\current\u user-m2\repository 到D:\repository或任何其他不带~的正常路径或任何其他特殊路径

3）在惊慌失措之前，用自己的maven检查控制台中的所有内容。例如，我的命令如下 mvn站点 mvn安装 mvn tomcat：重新部署

在控制台上工作得很好，但在eclipse内部失败。这意味着m2eclipse参数是错误的，您应该设置自己的参数

4）不要依赖上下文命令（右键单击-runas-maven test/site/build）在runas-maven build-in菜单中创建您自己的命令选择正确版本的JRE（在我的例子中是1.7）并添加任何其他参数不要忘记给这个命令起个名字，比如：“maven-tomcat:redeployJDK 7”-这将给您一个很好的机会运行您想要的任何东西，并且不会面临90%的Eclipse问题和bug

另外，我在maven 2和m2eclipse上挣扎了20多个小时。希望我的建议对某些人有用

m2eclipse有时会出现这种情况，这是因为当您向pom.xml添加新的依赖项时，m2e会自动将其添加到类路径中，并且此类路径生成有一些问题

一个快速而肮脏的修复方法是

```
从eclipse中删除项目
```

现在

导航到项目文件夹

和

删除.settings目录和.classpath文件

将项目作为“Maven项目”导入eclipse

在运行按钮（带有绿色三角形的按钮）中，选择运行配置
进入“maven build”类别，并查找您的项目中的一个
检查maven运行时、JRE和类似的东西是否正确配置：在eclipse中更改时不会刷新这些值
应用更改并运行
