Hello, I’m looking at the SDK examples, specifically the “opc-ua-device”. I’m using Eclipse IDE, and when I open a source file, trying to use code completion (CTRL + Space) I get this error message:

“This compilation unit is not on the build path of a java project”

Anyone knows what’s the problem?
