Why is network already up to date while trying to deploy a contract on truffle

Question

I have just started writing smart contracts in solidity using truffle framework. For testing, I'm using ganache.
I executed the following steps as mentioned on truffle site

truffle deploy (for deploying my contract on the network
truffle test (to test my contract)
truffle deploy (if I run this command again, it says that "Network up to date"

However, on restarting the ganache, and then executing the same command, it worked.

Answer 1

I guess you have ganache running already in the background and you have deployed and migrated a contract already on the network, and if you'll try to deploy the same contract again without the changes, it won't let you do it, because you are deploying the same contract which is already deployed on the network.

However, if you want to deploy the same contract again,then you have two options:either, delete the json files from the build directory or you can forcefully redeploy the contract by executing : truffle deploy --reset

Answer 2

If you want to only migrate all contracts without deploying, then you can run the following command

 truffle migrate --reset
