My source maven project is of archetype 19 and getting below error:
********** Executing Repository Modernizer **********
Error: ENOENT: no such file or directory, stat
The prior version exhibited this symptom, and the way to work around it was to perform a non-global install of @adobe\aem-cs-source-migration-repository-modernizer in the same folder in which you're running the aio plugin from.
$ cd project-to-modernize
$ npm i @adobe\aem-cs-source-migration-repository-modernizer
But that said, that was fixed in v0.0.8 so just upgrade to the latest version and you should be set.
