Support building crates that use resolver 2
Maldron opened this issue · comments
If a crate (or any of its dependencies) has opted in to resolver 2, it won't currently build with dinghy. The 2021 edition will make resolver 2 the default for new crates (rust-lang/cargo#9048), so this will probably become a widespread issue over time.
To reproduce, create a new empty library like cargo new resolver_2_test --lib, then add resolver = "2" to resolver_2_test/Cargo.toml. Then run dinghy as normal with cargo dinghy -d rust_test_simulator test, and you'll get the following error:
[2021-07-27T20:59:01Z ERROR cargo_dinghy] failed to parse manifest at `/Users/.../resolver_2_test/Cargo.toml`
Caused by:
feature `resolver` is required
this Cargo does not support nightly features, but if you
switch to nightly channel you can add
`cargo-features = ["resolver"]` to enable this feature
