Handle two-line anchor version output breaking CI#98
Merged
Conversation
The Anchor matrix aborts at toolchain setup with:
##[error]Unable to process file command 'output' successfully.
##[error]Invalid format '1.1.2'
heyAyushh/setup-anchor@v4.999 detects an existing install with
`anchor --version | awk '{print $2}'` and writes the result to
$GITHUB_OUTPUT. `anchor --version` now prints more than one line, so the
value is multi-line and the write fails, killing every matrix group before any
project is built. It only surfaces when the Anchor matrix actually runs (a
change touches an Anchor project), which is why main looks green.
Replace the action in anchor.yml with the same install steps (Solana via the
Anza installer, Anchor via avm) plus toolchain caching, and read the version
from the first line only so a multi-line value can't break the run. The other
workflows using setup-anchor (native, quasar, pinocchio, solana-asm) share the
latent bug and can be migrated the same way once this is confirmed green.

Problem
The Anchor workflow aborts at toolchain setup, before any project is built:
heyAyushh/setup-anchor@v4.999detects an existing install with:anchor --versionnow emits more than one line, soawk '{print $2}'returns a multi-line value, and writing a multi-line value to$GITHUB_OUTPUTfails withInvalid format. That kills every matrix group at setup.It only surfaces when the Anchor matrix actually runs (a change touches an Anchor project).
mainlooks green because its last run changed no Anchor projects, so the matrix was skipped andsetup-anchornever ran — the bug is latent, not absent.Fix
Replace
setup-anchorinanchor.ymlwith the same install steps it performs — Solana via the Anza installer, Anchor viaavm— plus toolchain caching, and read the Anchor version from the first line only (head -n1) so a multi-lineanchor --versioncan never break parsing again.The action's own master branch still has the buggy
awk '{print $2}', so pinning to another tag would not help.Scope / follow-up
anchor.yml. Editing the workflow file triggers a full-matrix run, so this PR's own CI exercises the new setup across every Anchor project.native.yml,quasar.yml,pinocchio.yml, andsolana-asm.ymluse the same action and share the latent bug; they can be migrated the same way once this is confirmed green.Validation
GitHub Actions changes can't be run locally — this relies on the PR's own CI to confirm the full Anchor matrix installs the toolchain and passes.
