How do you all solve multi-network development with truffle? Whenever I try migrations between networks (i.e. local ganache to rinkeby) I always get an error that compiling was done with a different compiler version so I have to end up deleting the build folder in order to migrate but then when I try going back to the intial network I get t`this contract has not been deployed to detected network` because I deleted the build folder

Thanks, so I just have to change the contracts_build_directory and that's where the networks build will live?

perfect

or wait

thats global

so that wont help

how do I do this for multiple networks?

simply define the networks on your truffle-config.js (see networks: {} ), then upon migrating, add a new flag --network (network_name)

this doesnt work

I have to delete the build folder in order to migrate on a new network

and then my old networks build is lost

is there a way to have multiple builds across different networks or do I have to have different git branches for each one which is what I'm currently doing (and its a huge pain)

as far as I know, the build will be the same regardless of the network/infrastructure

No that's not true, network details are stored in the artifact

This is the network ID which is my openethereum node running in kubernetes.

If I try to run migrations on Rinkeby, (network ID 4) it fails because this artifact is in the build folder under network ID 17

These contracts are upgradeable so I need to preserve the builds across all my networks.

and so deleting the build folder is out of the question. I have to have seperate git branches for each network but that is so convoluted and cumbersome, there must be somethign I'm missing

I don't think I have this in my artifacts

You do. It's in all the compiled json files under build
