简单的说就是和workspace resolution这个特性有关，In 0.9.7默认的maven的启动配置已经被修改为“pickup setting for workspace dependency resolution from the project settings”，而不是所有的maven插件都可以在workspace dependency resolution开启的情况下工作。比如这次maven Assembly plugin就犯错了，可以通过在maven的启动配置中关闭这个特性来解决这个问题。

    解决的方法很简单，右键单击要执行package的project，"properties for ***" -> maven，将"resolve dependencies from workspace projects"前的勾取消。
