Make sure you have the Migrations.sol and that the name of the contract is the same as the name of the file, that solved the issue for me.

I was having the same issue and it came down to the MyContract.sol file being in the main project directory instead of the ../contracts/ directory. Also ensure that you have a constructor in your contract that initializes the code you’re trying to run.

As @pianchemist said, truffle init turns the folder in which you run the command into the staging directory for your project and sets up standard default files and structure. The creation of files after this and placing them in the correct directories are up to you. For simple projects, having your contract within the contracts directory is as complex as it needs to be. For larger projects, it works like any other programming structure: you may have a folder that contains library code, or a hierarchy of contracts depending on the complexity of your project.

Regardless of size and complexity, ensure that your config is pointing to the correct locations using the staging directory as the root of the project. Ensure that any import statements also point to the correct location.
