Cargo uses absolute paths somewhere #55072
Description
I am trying some embedded rust programming and figured out that the cargo/rustc cache does not survive a move of the project folder. (This is the cortex-m-quickstart project but I think that does not really matter.)
There are no absolute paths neither in .cargo/config nor in Cargo.toml. After a cargo clean I can do a build again.
PS C:\Users\danie_000\Code\RE\ABC> rustc --version
rustc 1.30.0-beta.15 (590121930 2018-10-12)
PS C:\Users\danie_000\Code\RE\ABC> cargo --version
cargo 1.30.0-beta (05e9b01fc 2018-09-21)
The rust version is set by rustup default beta and not overwritten for any of these folders.
After the rename of the Project folder, cargo summons rustc with some references to the ABC path that does not exist anymore.
