Collator build fails on the first run

[JoshOrndorff]

On the rococo_v1 tag (and probably on master) when I do a clean checkout and build the collator with cargo build --release -p rococo-collator, the command fails with the following (full error):

error: failed to run custom build command for `westend-runtime v0.8.22 (https://github.com/paritytech/polkadot?branch=rococo-branch#e9164236)`

Running the exact same command without changing anything succeeds the second time.

Yeah that is a bug in the wasm-builder, which I still don't know on how to solve it..

I'm so used to it I don't even see it anymore

This issue is now preventing the docker image from building in the cumulus workshop. Is there a workaround? The best thing I can think of is to run cargo build --release three times in the Dockerfile. That's how I get around it locally.

run cargo build --release three times in the Dockerfile

Is this a magic spell @JoshOrndorff ?

I really need to fix this. I already invested some thoughts and maybe just should get started and try my ideas.

Did you sovled it? My VSCode always show me this error and it looks like makes the rust-analyzer extension stop working

[bkchr]

Nope still exists.
