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

做NC的时候从别人那拷了个NC_DEMO结果我这报错他那没报错
import nc.bs.wfengine.engine.ext.TaskTopicResolver;

报错信息: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

解决方案1:

Eclipse 默认把这些受访问限制的API设成了ERROR。
Windows -> Preferences -> Java -> Compiler -> Errors/Warnings ->
Deprecated and trstricted API -> Forbidden reference (access rules): -> change to warning

解决方案2:
只需要在project build path中先移除JRE System Library,再添加库JRE System Library,重新编译后就一切正常了。

解决方案3:

工程上右键->工程属性->java builder path->Libraries标签,点击JRE System Library里面的Access rules,add sun/** 为accessible,如果该项存在,就edit。

解决方案4:

Windows -> Preferences -> Java -> Installed JREs -> 选择用的JDK -> Edit -> Add External JARs

俺试了下1,4可行。。。我只是我的,具体每个的差别没研究,谁有研究 给个消息
