scrypto build of workspace fails

[cjdsellers]

Hi all,

We have a large multi-crate scrypto project with a top level Cargo.toml manifest defining a workspace. Running scrypto build from the top level fails with the following output (redacted):

Error: BuildError(InvalidManifestFile("<..redacted..>Cargo.toml"))

There is no additional stack trace even when running with RUST_BACKTRACE=1 or with the --trace option.

Running cargo check finishes successfully which means all Rust syntax is correct, and the workspace is defined correctly.

Also running cargo build --target wasm32-unknown-unknown --release --target-dir target --manifest-path Cargo.toml succeeds, which afaik is what scrypto build is essentially running.

The slightly redacted workspace manifest looks like this:

[workspace]
resolver = "2"
members = [
   ... a bunch of crates
]

[workspace.package]
rust-version = "1.73.0"
version = "0.1.0"
edition = "2021"

[workspace.dependencies]
sbor = { git = "https://github.com/radixdlt/radixdlt-scrypto", tag = "v1.0.0" }
scrypto = { git = "https://github.com/radixdlt/radixdlt-scrypto", tag = "v1.0.0" }

# dev-dependencies
transaction = { git = "https://github.com/radixdlt/radixdlt-scrypto", tag = "v1.0.0" }
radix-engine = { git = "https://github.com/radixdlt/radixdlt-scrypto", tag = "v1.0.0" }
scrypto-unit = { git = "https://github.com/radixdlt/radixdlt-scrypto", tag = "v1.0.0" }
radix-engine-stores = { git = "https://github.com/radixdlt/radixdlt-scrypto", tag = "v1.0.0" }
rand = "0.8.5"

[profile.release]
opt-level = 's'        # Optimize for size.
lto = true             # Enable Link Time Optimization.
codegen-units = 1      # Reduce number of codegen units to increase optimizations.
panic = 'abort'        # Abort on panic.
strip = "debuginfo"    # Strip debug info.
overflow-checks = true # Panic in the case of an overflow.

Are we doing anything obviously wrong? or is this a known issue currently, with a workaround?

It would be great to be able to run scrypto/cargo commands from the top level of the source, as this will make setting up CI/CD much easier, also more efficient just compiling the subdependency crates once with a single Cargo.lock and target dir.

Thank you for all the hard work which went into getting scrypto to v1!

Looking forward to your response.
