I'm using clippy on travis.
As we all know, clippy sometimes fails to catch up in time and a nightly without clippy is shipped.
To mitigate failure of my travis job in this case, I was installing clippy from the git repo if it was not shipped with the nightly:
1
2
3
| &＃096;
- if [[ "$CLIPPY" &＃061;&＃061; "true" ]]; then rustup component add clippy-preview --toolchain&＃061;nightly || cargo install --git https://github.com/rust-lang-nursery/rust-clippy/ --force clippy ; fi
- if [[ "$CLIPPY" &＃061;&＃061; "true" ]]; then cargo clippy --all-targets --all-features -- -D warnings ; exit ; fi |
`
However it seems this no longer works:

Thanks!
The problem is that afaik we cannot force to install (not update-to) a nightly that has clippy, if the latest nightly does not ship clippy.
