joda time 2.0

You need to explicitly include 'joda-convert', which is marked as a
optional dependency in the joda-time POM [1]

org.joda
joda-convert
1.1

The Scala compiler requires that all classes referenced in signatures
of classes that you use are also available on the compile time
classpath.

This library dependency should be optional. Annotations in Java are
optional - if they aren't found, the class still loads and runs.
Clearly Scala isn't respecting that.

I only included this in Joda-Time because of how Java annotations are
optional. No one should be forced to pick this up this as a
dependency. Can Scala be changed/fixed?

You only need it at compile time, use the "provided" scope in Maven for that.

Has anyone any suggests as to what I can do about this as a user?
I'm compiling within intellij using the scala module.

The problem is that I get this;
error while loading Period, Missing dependency 'class
org.joda.convert.FromString', required by C:\programmingExperiments
\joda-time-2.0\joda-time-2.0.jar(org/joda/time/Period.class)

repeated for each of the types at the top of the Make error list. It
doesn't tell me which or what I need to modify in order to make it go
away.
Does this mean I simply can't make it compile, or do I have to go
around importing org.joda.time.convert._into every scala file that
requires it?

Has anybody any interest in sorting this out? Or are you just going to
blame each other? Right now it looks like I've got to go back to a
previous version of jodatime, which is a shame because I do use joda
everywhere.

Add this JAR to your classpath:

org.joda
joda-convert
1.1
