Tested locally with this:

nextflow run nf-core/rnaseq -r 3.17.0 -profile test,conda --outdir dir

Breaks on the released version and works fine with this PR build 🎉

[ewels]

If we could get this into a patch release that would be amazing 🙏🏻

[pditommaso]

Made a change to use normalised absolute path + using more compact sip hash algorithm.

How this solution is going to be validated?

I could try to add an integration tests that installs miniconda and runs the pipeline which reproduces the error. Do you think it is enough?

[pditommaso]

I was more thinking running a real pipeline to replicate the problem. Maybe @ewels knows more

I was trying to validate earlier this morning already, but couldn't get the original error to trigger any more 🙈

I'll clean up my env and try again shortly. Maybe @maxulysse or @pinin4fjords could also have a go?

I can definitively replicate the original error

[pditommaso]

@maxulysse nice. Are you able to make a local build with this branch and try it?

It's a success 🚀

[pditommaso]

Great!

I was too slow, but I just checked on GitPod and was able to replicate the error and confirm that it's now fixed on master 👍🏻
