Maven 报错处理

从svn拉项目时，如果一个项目有多个子工程，1).  直接从trunk下拉项目，例如wm6-jzmd-project-latest（荆州电子）、wm6-ttbeer-project（青啤），然后在eclipse里import-->Existing Maven Projects根据引导下一步直到完成；2).  然后右键上面两个项目名称下面的pom.xml（即一级工程下）Maven-->Update Project...就可以获取伺服上的jar资源库(如果还是没有成功下载到私服上的jar，一般都是maven的settings文件配置有问题)。----除了如下两个原因外，网速也是可能原因之一，尽量在网络空闲时间update项目。

1.   pom.xml文件报：maven-enforcer-plugin is ignored by m2e 原因及处理办法：(pom.xml文件中execution报错处理)

It looks like that error is due to a missing <pluginManagement> tag. So, in order to avoid the exceptions in Eclipse, it looks like one needs to simply enclose all the plugin tags inside a <pluginManagement> tag, like so:

<build>
<pluginManagement>
<plugins>
<plugin> ... </plugin>
<plugin> ... </plugin>
....
</plugins>
</pluginManagement>
</build>

然后Maven右键-->Update Project...

2. 当编译maven项目不能下载伺服上jar时，可能是maven的setting.xml文件配置问题，例如如下，

repository中配置了两个id:Swisslog和Swisslog Repository，那么在servers中需要分别对应两个server及相应的id、username、password
