Package siddhi extensions in one jar

Question

I am new to Siddhi, I originally used Eclipse for development and used "package required libraries into generated jar" to package all dependencies into one jar file, this way it worked fine.

But when I try to use intellij for development, and use maven to package all the dependencies into one jar file and run it, it comes up with ExtensionNotFoundException.

Exception in thread "pool-4-thread-1" io.siddhi.core.exception.ExtensionNotFoundException: Error on 'SiddhiApp' @ Line: 35. Position: 91, near '@sink(type='file',append = "true",file.uri = "alert.csv", @map(type='csv', header='false'))'. No extension exist for sink:file
