cargo run -p meroctl -- --node-name node1 --home data bootstrap start --merod-path {path} --app-path {path}
or with app download
cargo run -p meroctl -- --node-name node1 --home data bootstrap start --merod-path {path}
If user didn't provide app-path, instructions at the bottom of log are provided. Otherwise not.

Run tests locally and they are passing
cargo build -p meroctl -p merod -p e2e-tests

@fbozic did you saw this error before?

You shouldn't use println in the commands, please use environment.output.. Because we consume command output in multiple formats. Potentially, this breaks your e2e-tests.
