Apache IVY error message? : impossible to get artifacts when data has not been loaded

Question

hey all, I'm getting the following error when trying to build a project via SBT in scala

[info] :: USE VERBOSE OR DEBUG MESSAGE LEVEL FOR MORE DETAILS
java.lang.IllegalStateException: impossible to get artifacts 
    when data has not been loaded. IvyNode = log4j#log4j;1.2.14

I don't see any of my projects referencing 1.2.14, nor is it in my .m2 or .ivy repositories. Not sure where to look for this one

a full error dump is here: http://pastebin.com/pM7NUhY0

thanks

One of your dependencies might be depending on log4j 1.2.14 transitively. Are you able to specify the log4j dependency directly in your project and force Ivy to download it? – Laodicea

when ivy says "use verbose or debug level" then it really means it as the errors it produces at normal logging levels are pretty obtuse. – Recount

Binil, that's what fixed it. If I manually add the log4 1.2.14 dependency it works, thanks – Liminal

Answer 1

Seems that this is related to IVY-987 and should be fixed in ivy 2.1.0-RC1.

Answer 2

I saw this recently with a junit dependency and it kind of drove me nuts trying to fix it. In my case I had to remove the "test" scope from the dependency declaration (in this case in SBT with Scala).

Anyway, hope it helps someone.
