Unable to import the Treet.java file in the repl

When I open the repl and type the commands Craig provides, it works until I try to import com.teamtreehouse.Treet

It tells me that it cannot find symbol, and it points to the period before Treet.

Any ideas? I couldn't make sense of anything on stack overflow...

Thanks in advance. :)

Is your Treet.java file in the relative directory "./com/teamtreehouse/"? If it is in our current working directory, you can try to use "import Treet".

Hi Chris,

Thanks for your help, when I type import .com/teamtreehouse/Treet.java;

I get a 'Does not exist'. It's definitely in the working directory, I can see it on the left under teamtreehouse

In the video, Craig is in the ~/workspaces directory which has three items: a directory com, Example.class and Example.java. He then does two steps to import Treet in the java-repl: load file, then import:

$ java-repl
Welcome to JavaRepl version 272 (Java HotSpot(TM) 64-bit Server VM, Java 1.8.0_20)
Type expression to evaluate, :help for more options or press tab to auto-complete
java> :load com/teamtreehouse/Treet.java
Loaded source file from com/teamtreehouse/Treet.java
java> import com.teamtreehouse.Treet;
Imported com.teamtreehouse.Treet

What are you experiencing that is different in your case?

I found the issue. Double check your Treet.java and Example.java files and make sure Example compiles without warnings.
