This is probably not the answer you are looking for and I admit it is not elegant but it currently works for me, meaning that I think it takes less time for me to periodically do the following instead of researching and finding a more elegant solution.

I assume you are using the sbt-eclipse plugin ( https://github.com/typesafehub/sbteclipse ). When I add new dependencies to my project ( which is actually pretty rare ) I simply regenerate my eclipse project files from the plugin. The downside of this is that I have a multiple module project and after I refresh the projects in eclipse I need to re-add the inter-project dependencies in the eclipse build path editor.

Like I mentioned it is pretty hacky but all in all I really don't loose that much time doing it. It's not pretty but it works.

Best of luck, Andy

The following works for me:

1) close project in Eclipse

2) in my file explorer, browse to my Eclipse project, make sure hidden files are visible

3) open .classpath in a simple text editor

4) copy the bottom entry. For example, in my current project, it is <classpathentry path="/home/natalie/.ivy2/cache/org.scalatest/scalatest_2.9.1/jars/scalatest_2.9.1-1.8.jar" kind="lib"></classpathentry>

5) navigate to my .ivy folder, cache, then down to the library I have added via sbt

6) right click on jar file, select properties, copy the path and jar file name and replace it in the entry I copied in step 4

7) save .classpath

8) open my project on Eclipse

New dependency is now available in Eclipse.

All you need is execute from your project home:

sbt "eclipse with-source=true"

or enter sbt console and write:

eclipse with-source=true

BTW: I don't know if from Jan '12 something has changed but now it seems much more simple.

In command prompt go to the project folder and type

sbt eclipse

This should generate the appropriate .classpath entries in eclipse project.

Go back to eclipse, select the project and press f5, this will reload the referenced libs.

I use the Apache IvyDE plugin for Eclipse, and I've had more luck with this approach. It's only described in the old sbt docs, but works with sbt 0.11

First, install the IvyDE plugin in Eclipse and restart.

Run the sbt command deliver-local - this will create an XML ivy file of your dependencies.

In Eclipse, under your Project/Properties - Java Build Path - Libraries, click "Add Library" and choose "IvyDE Managed Dependencies" then select the file target/scala-2.9.1/ivy-projectversion.xml

When you add a new dependency to build.sbt, run the sbt commands reload and deliver-local again. Then right-click the Ivy library for your project in the Package Explorer - it will be called "target/scala-2.9.1/ivy-projectversion.xml [compile,test]", and click the second "Refresh" menu item (between "Refresh" and "Reload Settings" - not "F5 Refresh" ).

If you are using sbteclipse plugin it's achievable in a simple way. In sbt type:

reload
eclipse with-source=true

Then in eclipse, hit F5 on a project folder to refresh it. Or right-click and choose "Refresh". Just works.
