Hi i am getting this error when i run nf-core/demultiplex It seems that the class AdapterRemover (from the lib/ folder) is not being imported to the demultiplex.nf . Were there any changes in nextflow v24 or in the revision that may have broken automatic importation of groovy classes in the workflow?

Have you tried removing the cache?

rm -rf ~/.nextflow/assets/nf-core/demultiplex

I have pulled an older revision (1.4.1) and now it works until compilation (it’s still running now). It seems that adding the AdapterRemover class broke the demultiplex.nf workflow
