warning: output filename collision.
The bin target `dotenv` in package `collab2 v0.28.0 (/Users/administrator/actions-runner-1/_work/zed/zed/crates/collab2)` has the same output filename as the bin target `dotenv` in package `collab v0.28.0 (/Users/administrator/actions-runner-1/_work/zed/zed/crates/collab)`.
Colliding filename is: /Users/administrator/actions-runner-1/_work/zed/zed/target/debug/dotenv
The targets should have unique names.
Consider changing their names to be unique or compiling them separately.
This may become a hard error in the future; see <https://github.com/rust-lang/cargo/issues/6313>.
