Hi! I recently added the meltano-map-transformer mapper to my project which has been (mostly) working as expected in the original project (where I ran

meltano add mapper meltano-map-transformer

). However I am having issues reproducing the environment on other machines: it seems that

meltano install

skips the installation of mappers, on purpose. I am able to force the mapper install by running the

meltano add mapper meltano-map-transformer

command again in the new environment (even though the mapper is already specified in meltano.yml config), but it does not seems ideal?

@ken_payne or @edgar_ramirez_mondragon do you know why that is?

I can confirm that

meltano install

skips the mapper when mappings are declared: https://app.warp.dev/block/l8260OaP1EJ9LeBGhUM2IS. If no mappings are declared, the plugin is correctly installed: https://app.warp.dev/block/YTUO3otJcXJuBPH2JJTqrd The offending line is https://gitlab.com/meltano/meltano/-/blob/029077cfb7d198073beda42a44857f78b6274293/src/meltano/core/plugin_install_service.py#L415. cc @florian.hines

Yea sounds like a bug. We're supposed to install the actual mapper plugin but skip installing the mappings, sounds like we skipping both.
