Motivation
- Enable correct NullAway analysis
- Pick up toolchain fixes and improvements
Toolchains
- Require JDK 25 for JVM toolchain (keep Java 17 runtime compatibility)
- Require Kotlin 2.3.20 for Kotlin toolchain (keep Kotlin 2.2 runtime
compatibility)
- Require JDK 25 for Gradle daemon JVM (via
gradle-daemon-jvm.properties)
- Fix javac and kotlinc warnings from toolchain upgrades
CI
- Bump GitHub workflows to JDK 25
Building Kotlin
- Bump Kotlin language level to 2.2 to match stdlib version
- Consolidate build logic into pklKotlinBase.gradle.kts
- Adopt modern Kotlin plugin syntax
- Fix new kotlinc warnings
- Update ktfmt to 0.62
- first version compatible with Kotlin 2.3.20
- changes formatting compared to 0.61
- Replace dependency resolution rule with BOM alignment
- rule was too broad and interfered with toolchain/runtime separation
Testing
- Expand matrix to JDK 25 (LTS) and 26
- Ensure each matrix task can be run independently
- Fix KotlinCodeGeneratorsTest and EmbeddedExecutorsTest on affected
JDKs
- Disable one test in CliCommandTest on affected JDKs (failure cause
unknown)
Compatibility fixes
- Fix reflective access in DocGenerator on affected JDKs
Build fixes
- Fix misuse of `task.enabled` vs. `report.required`
- Fix `gradlew tasks` on Windows
- Downgrade Spotless to 8.3.0 to (hopefully) work around sporadic
NoClassDefFoundError
Result
- NullAway runs correctly
- Broader JDK test coverage
- More reproducible and potentially faster builds
This avoids an issue where, during the course of development, a file is
touched, thus modifying the copyright year.
Then, undoing the previous change does not undo the copyright year
change.
This changes the Gradle build to always create multi-jdk tasks,
and instead use the `enabled` property to determine whether the task
is actually ran or not.
The has the following benefits:
* IntelliJ and other tools understand the task execution graph (e.g. testJdk20 shows up as a task)
* JDK-specific Gradle configurations always exist, so `updateDependencyLocks` is consistent.
The change ensures the generated bytecode adheres to the APIs
for the target Java release.
Previously, only sourceCompatibility and targetCompatibility were used,
and they might cause issues like NoSuchMethodError when a newer javac
compiles with -target older_release.
Note: it is good to use a new an up to date javac to avoid issues
in the compiler itself, so having a proper `-release ..` configuration
is vital.

This updates the GraalVM and Truffle libraries to 2024.1.2.
This also updates the build logic to compile Java sources using Java 21, due to some compile-only dependencies within GraalVM/Truffle using class file version 65. However, the produced artifact is still compatible with Java 17.
This also changes the Gradle build logic to use toolchains, and to test the Java libraries with JDK 17 and 21.
One consequence of this change is that Truffle is no longer shaded within the fat jars.
feat: support for jvm21+ toolchain
feat: support for gradle toolchains
feat: pass -PnativeArch=native to build with -march=native
test: multi-jdk testing support
test: support for jvm-test-suite plugin
test: add tasks to run jpkl eval on multiple jdks
test: make jdk exec tests respect multi-jdk flags and ranges
fix: remove mrjar classes at >jvm17 from fatjars
fix: use jdk21 to run the tests (needed for Unsafe.ensureInitialized)
fix: truffle svm dependency is required after graalvm 24.0.0
fix: warnings for gvm flag usage, renamed truffle svm macro
fix: build with --add-modules=jdk.unsupported where needed
fix: don't use gu tool for modern graalvm versions
fix: catch Throwable instead of deprecated-for-removal ThreadDeath
chore: buildinfo changes for JVM targets, toolchains
chore: enforce testing at exactly jdk21
chore: enforce build tooling at jdk21+
chore: bump graalvm/truffle libs → 24.1.2
chore: toolchains for buildSrc

* Remove unnecessary strictfp modifier
* Add annotations to address Truffle DSL warnings (@Idempotent, @Exclusive)
* Adjust build logic to allow building cross-arch on macOS
* Add warning suppression for specialization limit (left this one as a TODO)
- Fix and clean up the pkl-commons-test build script.
- Change tests to read test packages/certs directly from
the file system instead of packaging and reading them
from the class path.
- Update expected checksums of some test packages.
- Fix a conflict between Pkl's and Gradle's
Kotlin libraries in the pkl-gradle project.
- Fix build deprecation warnings.
- Ensure Gradle distribution integrity with `distributionSha256Sum`.
- Manually verify integrity of Gradle wrapper added by this commit.
- fix: make version catalog accessible from `buildSrc` plugins
- chore: declare `googleFormatVersion` in version catalog
- chore: declare `ktfmt` in version catalog
