Can cargo dist build exactly the binary?

[tisonkun]

I built a project that has several test-only, non-binary crates.

Now when cargo-dist runs cargo dist build, those crates will be built and some of them may fail - https://github.com/tisonkun/morax/actions/runs/11226860397/job/31208119385?pr=9

Since those crates have nothing to do with the binary I'd like to release, I wonder if it's possible to exclude their build.

You can try adding a [metadata.dist] section to their Cargo.toml files with dist = false - that will tell cargo-dist not to try to build them. https://opensource.axo.dev/cargo-dist/book/reference/config.html#dist

@mistydemeo thanks for your suggestion. But it doesn't seem to work.

It failed with https://github.com/tisonkun/morax/actions/runs/11227771504/job/31210572728

It seems that the rdkafka crate still built although all its dependent is excluded by package.netadata.dist.dist = false.
