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
