Adobe flash builder 4.7 gives "Internal error" when trying to create Apache Flex JS project

Hi,

I am trying to create Apache Flex JS project in Adobe flash builder 4.7. It gives  "An internal build error has occured. See the error log for more information". Error in error log states : "Uncaught exception in compiler  com.adobe.flexbuilder.project". Also it's not generating any file in  bin-debug folder.

The above stated problem only occurs, when trying to create a project by  targeting Apache FLEX JS 0.8.0 SDK. However, flash builder doesn't produce any error when project is created by targeting Apache Flex 4.16.0 Sdk.

Thanks in advance.

Regards
