运行product

[quote]The activator com.siemens.ct.mp3m.Activator for bundle com.siemens.ct.mp3m is invalid [/quote] 你弄得这个不可用.

我刚才down了一个，直接运行了下，什么问题都没，我是从官网上checkout下来的，你这个错误是怎么来的呢？我也看了下，这个就是你运行错了，我说的不错的话你运行的应该是com.siemens.ct.mp3m，但实际上不是这个，这个只是个RCP，RCP要以poduct运行添加它的必须jar，你试着运行一下branding.blue和branding.orangle吧两种风格

真不知道你是怎么把这些错误弄出来的，我down下来直接运行就OK eclipse modeling3.5.2
