Summary

  • mise 2026.10.5 changed the default vendor for a bare java version from OpenJDK to Temurin (release notes). Our mise.lock records OpenJDK with shorthand_vendor = "openjdk", so mise install --locked fails with mise 2026.10.5 or later:
    mise ERROR Failed to install core:java@latest: java@latest is not in the lockfile
    
  • This breaks the "Deploy to GitHub Pages" job, which installs the newest mise because the workflow does not pin a mise version. It also breaks the mise install --locked enter hook for developers on a current mise.
  • This PR keeps java = "latest" and runs mise lock --bump java. The lock moves from OpenJDK 26.0.1 to Temurin 27.0.0+35.
  • Temurin publishes no macOS x64 build of Java 27, and the bump fails while the lock covers that platform. So mise.toml now sets lockfile_platforms to the platforms the lock already covered, without macos-x64. Developers on Intel Macs get no locked Java.

Only the Java lock entries change. hugo, lychee and maven keep their current entries.

CI does not use mise's Java. Tests, checkstyle and api-compat use actions/setup-java.

Verification

  • Generated with mise 2026.10.10.
  • Checked mise install --locked with mise 2026.10.9 (the version CI selects now) and 2026.10.10.
  • Did a real mise install --locked java on linux-x64, and ran java -version.
  • Compared all 6 new Java checksums with Adoptium's published .sha256.txt files. All match.

Summary by CodeRabbit

  • Build & Compatibility
    • Lockfile platform coverage now includes Linux arm64/x64 (including musl), macOS arm64, and Windows x64. macOS x64 is excluded.

mise 2026.10.5 changed the default vendor for a bare `java` version from
OpenJDK to Temurin. Our lock records OpenJDK with
`shorthand_vendor = "openjdk"`, so with mise 2026.10.5 or later,
`mise install --locked` fails with "java@latest is not in the
lockfile". This breaks the Pages workflow and the mise enter hook.

Run `mise lock --bump java` to lock `java = "latest"` to Temurin. This
moves the locked version from OpenJDK 26.0.1 to Temurin 27.0.0+35.

Temurin publishes no macOS x64 build of Java 27, and the bump fails
while the lock covers that platform. Set `lockfile_platforms` to the
platforms the lock already covered, without macos-x64. The other tools
keep their existing lock entries.

📝 Walkthrough

The mise.toml configuration sets the lockfile platforms to Linux arm64 and x64, including musl, macOS arm64, and Windows x64. It excludes macOS x64 and notes that Temurin has no macOS x64 build for Java 27.

Changes: Lockfile platforms

Layer / File(s) Summary

mise.toml
The configuration lists Linux arm64 and x64, including musl, macOS arm64, and Windows x64. It excludes macOS x64 and adds a comment about Temurin’s Java 27 build availability.

Change: Bug fix

Merge Risk: 🔵 Low · up to c8cff

Lock generation on Intel Macs can fail because the host platform is added despite being omitted from the configured list. An explicit supported platform list or Intel-compatible Java selection provides a bounded workaround, so the PR is mergeable with contributor awareness.

🌐 Web query:

site:mise.jdx.dev "lockfile_platforms" "current platform" mise lock --platform

💡 Result:

`lockfile_platforms` applies when you run `mise lock` without `--platform`; mise adds the current platform to the configured list. An explicit `mise lock --platform …` overrides the setting and targets only the platforms you specify. ([mise.jdx.dev](https://mise.jdx.dev/configuration/settings.html?utm_source=openai))

If `lockfile_platforms` is unset, mise uses platforms already in the lockfile, or common defaults for a new lockfile. ([mise.jdx.dev](https://mise.jdx.dev/cli/lock?utm_source=openai))

Exclude macos-x64 from lock generation on Intel Macs.

mise lock adds the current platform to lockfile_platforms. On an Intel Mac, it can therefore resolve java = "latest" for macos-x64, where Temurin 27 has no matching build. Use an explicit supported --platform list when generating the lockfile, or provide an Intel-compatible Java selection.
