从SBT导入的第3方库找不到包

Question

I'm using Play 2.6 with Scala - but this may not be a Play issue.

I've built the project using SBT, and found a lovely CSV file reader library I wanted to use in my project. So I import it into my build.sbt as follows:

libraryDependencies ++= Seq("com.github.tototoshi" %% "scala-csv" % "1.3.4")

And do a refresh project. I go to use one of its static methods in a class of mine, and IntelliJ suggests an auto-import, which I add to the class:

import com.github.tototoshi.csv.CSVReader

class MyClass { ... }

But when I go to compile this via localhost:9000 in the browser, I get this error:

object github is not a member of package com

I'm new to using 3rd party libraries, but how can it not find the imported library? It told me where to find it, so it's in there somewhere. Should I change anything?

Thanks.

EDIT

It was a Play issue. I was trying to run my application from the browser - from my understanding the application compiles itself when you try to load your application after making changes.

Answer 1

You can use RootProject to reference an external build. You can find details and examples here - https://github.com/harrah/xsbt/wiki/Full-Configuration#project-references .

Answer 2

It was a Play issue after all. I think SBT needed to do a compile on its own after I took the above steps.

I simply shut down the localhost server I was running from, did a sbt clean compile run and that fixed the issue.
