解决mvn install问题Failure to find ** was cached in the local repository

项目是eclipse+maven管理的多模块项目，有两个子模块，myproject-common和myproject-web。工程结构如下：
myproject
|__myproject-common
|    |__src...
|    |__pom.xml
|__myproject-web
|    |__src...
|    |__pom.xml
|__pom.xml

在myproject-web上点击右键，选择Run As -> Maven install 报错：

Failed to execute goal on project myproject-web: 
Could not resolve dependencies for project com.mycompany.myproject:myproject-web:war:1.0: 
Failed to collect dependencies for [com.mycompany.myproject:myproject-common:jar:1.0 (compile), junit:junit:jar:3.8.1 (test)]: 
Failed to read artifact descriptor for com.mycompany.myproject:myproject-common:jar:1.0: 
Failure to find com.mycompany.myproject:myproject:pom:1.0 in http://mycompany.com/nexus/content/groups/public/ was cached in the local repository, resolution will not be reattempted until the update interval of archiva.internal has elapsed or updates are forced -> [Help 1]

然后在本地和远程的maven repo仓库中都加入了myproject-common的jar包，问题依旧。。。

最后在myproject工程上执行Run As -> Maven install 后再在myproject-web工程上点击右键，选择Run As -> Maven install，SUCCESS!!
