使用Eclipse建立Dynamic web project时出现错误

[rita_zoe]

是最后一步出现的错误的，提示是“One or more constraints have not been satisfied”点开详细信息是：One or more constraints have not been satisfied.
Cannot install project facet Java 6.0. Some version of this project facet is already installed.


请问这是怎么回事啊？

不知道,帮顶

好像是说已经存在一个版本了.

[kittaaron]

设下Eclipse编辑器级别看下.
窗口-首选项--JAVA-编译器-一致性级别.

同样的问题。有高手可以帮忙解决下嘛！

[西宝三元]

应该是插件的问题
先选择2.5
然后再选择3.0
回去选择一下就OK了
你试试吧
