Fails to verify contract ( err: Unable to locate a contract with the name )

Environment information

• ape and plugin versions:

  $ ape --version
  0.8.2
  $ ape plugins list
  Installed Plugins
  etherscan    0.8.0
  hardhat      0.8.0
  infura       0.8.0
  solidity     0.8.0

• Python Version: 3.9.5

• OS: linux (docker)

What went wrong?

Tried verifying the contract with publish: True, I got error that it's unable to locate a contract.

• what command you ran ape run deploy_cicada --network :sepolia:infura ( This is a script to deploy a contract named PrivateVote under src/PrivateVote.sol )
• the code that caused the failure (see this link for help with formatting code)

  
  import click
  from ape import project, networks, accounts
  from ape.cli import (
  ConnectedProviderCommand,
  network_option,
  ape_cli_context,
  )

@click.command(cls=ConnectedProviderCommand) @ape_cli_context() @network_option() def cli(cli_ctx, network): """ Get public parameter of cicada vote instance """ try:

custom gas fee

    max_fee = '200 gwei'
    max_priority_fee = '10 gwei'
    # Check network details
    ecosystem_name = networks.provider.network.ecosystem.name
    network_name = networks.provider.network.name
    provider_name = networks.provider.name

    click.secho(f"Selected network: {network_name}", fg="blue")

    account = accounts.load("olas")

    click.secho(
        f"You are connected to network '{ecosystem_name}:{network_name}:{provider_name}'.",
        fg="yellow",
    )
    click.secho(f"Deployer is set to '{account}'.", fg="yellow")

    # Deploy the contract
    click.secho("Deploying the PrivateVote contract...", fg="green")
    project.PrivateVote.deploy(sender=account, publish=True, max_fee=max_fee, max_priority_fee=max_priority_fee)
    click.secho("Contract deployed successfully!", fg="green")
except Exception as e:
    click.secho(f"An error occurred: {e}", fg="red")

- full output of the error you received

Unable to verify. Unable to locate a contract with the name 'PrivateVote.sol:PrivateVote', did you specify the correct Contract Name?

Have attached a txt file that contains the output from terminal for command run with ```-v DEBUG```

As an aside, there are some things with your script I want to comment on!

1. Since 0.7.0, you no longer need to specify @network_option() with ConnectedProviderCommand, you get it automatically and it works better without it
2. When using ConnectedProviderCommand, you can also accept provider and ecosystem right in the command args,

Here is an example!

@click.command(cls=ConnectedProviderCommand)
@ape_cli_context()
def cli(cli_ctx, ecosystem, network, provider):
    ...
    # No need for lines like `network_name = networks.provider.network.name`
    click.secho(f"Selected network: {network.name}", fg="blue")

(Partially shilling this feature)

And also, for the record, I am looking into the issue now and working on ape-etherscan as a whole

Worked for me https://sepolia.etherscan.io/address/0xd9aaBA4a0Cf1F087cEc266e2811e8ae5cAb1Faf3#code

Thanks @antazoey
