issues in install

(1)unable to import tochal
when I import tochal in eclipse, it shows many errors, mostly about "CGNode cannot be resolved to a type".

(2)unable load chrome extension
when I load chrome extension, it shows "Failed to load extension from: ~/Desktop/workspace/tochal/src/main/resources
Manifest file is missing or unreadable."

Hoping someone can tell me how to fix it, thanks in advance!
