Access restriction: The type TaskTopicResolver is not accessible due to restrict

做NC的時候從別人那拷了個NC_DEMO結果我這報錯他那沒報錯 
import nc.bs.wfengine.engine.ext.TaskTopicResolver;  

報錯信息:Access restriction: The type TaskTopicResolver is not accessible due to restriction on required library NC_DEMO/NC_HOME/modules/uap/META-INF/lib/uapplatform.jar 

解決方案1： 

Eclipse 默認把這些受訪問限制的API設成了ERROR。 
Windows -> Preferences -> Java -> Compiler -> Errors/Warnings -> 
Deprecated and trstricted API -> Forbidden reference (access rules): -> change to warning 

解決方案2： 
只需要在project build path中先移除JRE System Library，再添加庫JRE System Library，重新編譯後就一切正常了。 

解決方案3： 

工程上右鍵->工程屬性->java builder path->Libraries標籤，點擊JRE System Library裏面的Access rules，add sun/** 爲accessible，如果該項存在，就edit。 

解決方案4： 

Windows -> Preferences -> Java -> Installed JREs -> 選擇用的JDK -> Edit -> Add External JARs 

俺試了下1,4可行。。。我只是我的，具體每個的差別沒研究，誰有研究 給個消息
