Cannot Perform Operation [message #275306] Fri, 05 November 2004 21:14 Go to next message

While typing a package name in my source code and I pause before
completely typing the whole package name, I get an error window popping up
called "Cannot Perform Operation" and it has the message "This compilation
unit is not on the build path of a Java project.".

Please, if anyone knows what I have to do to get the system to either
recognize this package as I type it in, or a way for me to turn off this
feature entirely I would much appreciate it. These pop ups are extremely
annoying.

I am using Eclipse 3.0.1 Build 200409161125. I always open my files from
the navigator view.

Thanks,
John Ling

Well this tells you that the file is not part of the source code because
it is not on the Java build path. Ensure that your project is a Java
project and that the file's container is on the Java build path.
