I think the answer above needs some update:

I was trying to create a dynamic directory to store my upstream build artifacts so I wanted to pass my upstream job build number to downstream job I tried the above steps but couldn't make it work. Here is how it worked:

1. I copied the artifacts from my current job using copy artifacts plugin.
2. In post build action of upstream job I added the variable like "SOURCE_BUILD_NUMBER=${BUILD_NUMBER}" and configured it to trigger the downstream job.
3. Everything worked except that my downstream job was not able to get $SOURCE_BUILD_NUMBER to create the directory.
4. So I found out that to use this variable I have to define the same variable in down stream job as a parameter variable like in this picture below:

This is because the new version of jenkins require's you to define the variable in the downstream job as well. I hope it's helpful.
