Describe the bug

When two 'script contracts' have the same name, and forge script is run for any function in the contract, forge crashes with this error:

➜  contracts git:(script-test) ✗ forge script src/deploy/Deploy.t.sol --sig "deploy()"--private-key <>
[⠰] Compiling...
[⠒] Compiling 1 files with 0.8.10
[⠘] Solc 0.8.10 finished in 1.13s
Compiler run successful
The application panicked (crashed).
Message:  called `Option::unwrap()` on a `None` value
Location: cli/src/cmd/forge/script/executor.rs:36

This is a bug. Consider reporting it at https://github.com/foundry-rs/foundry

Backtrace omitted. Run with RUST_BACKTRACE=1 environment variable to display it.
Run with RUST_BACKTRACE=full to include source snippets.
[1]    6716 abort      forge script src/deploy/Deploy.t.sol --sig "deploy()" --rpc-url  --private-ke

It is likely that having two contracts with the same name in different files is not ideal (or possibly not valid, they compiled fine). However, if that is the case then forge should detect this and print a friendly error.

Thanks!

are both contracts actually contracts or is one an interface?

I ran into this today. Basically what I did was clone a script (Deploy.s.sol) and renamed it (to Mint.s.sol), changed the content, but forgot to change the name of the new contract from DeployScript -- leading to the above error and no hint as to why I was seeing it.

Renaming the contract in Mint.s.sol (and eliminating the duplicated script contract name) resolved the issue.

Optimistically marking as resolved

Recreating a setup with a duplicate CounterScript now returns:

Error: 
Multiple contracts found with the name `CounterScript`

Running against a direct path forge script script/Counter2.s.sol yields no errors
