Replace pkl-core's local nullness annotations with JSpecify annotations.
Enable NullAway checking for pkl-core packages except org.pkl.core.ast
and org.pkl.core.stdlib.
Notable code changes:
- Add a dedicated late-init constructor to VmTyped
- Move VmExceptionBuilder's fallback message derivation from withCause()
to build()
- Split VmException rendering between builder-provided messages and
string-backed messages
- Initialize MessageTransport handlers with default throwing handlers
- Update JSON helper collection types to allow nullable values JSON
arrays and objects can contain JSON null,
so the Java Map/List element types need to model nullable elements
explicitly
- Make public command transform APIs accept nullable transformed values
Command transforms can produce null for optional/default handling,
so the BiFunction and options-map element types now model that
explicitly
- Make ExecutorSpiException accept nullable message and cause
Existing call sites can pass nullable causes from Throwable.getCause()
- Remove JSR-305 semantics from `@LateInit`
JSpecify does not support the same type-qualifier-nickname pattern,
so `@LateInit` is now documentation plus a NullAway
constructor-initialization exemption
Out of scope:
- NullAway checking of org.pkl.core.ast and org.pkl.core.stdlib
- IntelliJ warnings related to `@LateInit` fields
- Removing the JSR-305 dependency, since concurrency annotations are
still in use
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
* Polish rewrite docs
* Add documentation comments, add missing evaluator options
* Add ability to set HTTP builder in ConfigEvaluatorBuilder
* Add ability to set rewrites in executor API
When we updated spotless's Java and Kotlin formatter, we changed the underlying
formatting rules.
However, due to spotless ratcheting, these formatting changes don't get applied unless a file
gets touched in a commit.
To avoid future PRs introducing lines of change that aren't related to the intention of the PR,
this is a one-time format of all files.
* Load `PklProject` using the same security settings and env vars passed provided via ExecutorSPIOptions
* Handle thrown `PklException` from loading `PklProject` and throw `ExecutorSPIException`
* Handle thrown `PklException` of older Pkl distributions, converting them into `ExecutorSpiException`
* Add version of resolved Pkl distribution to `ExecutorException`
* Review comments

Instead of bundling Pkl's built-in CA certificates as a class path resource and loading them at runtime,
pass them to the native image compiler as the default SSL context's trust store.
This results in faster SSL initialization and is more consistent with how default certificates
are handled when running on the JVM.
Further related improvements:
- Remove HttpClientBuilder methods `addDefaultCliCertificates` and `addBuiltInCertificates`.
- Remove pkl-certs subproject and the optional dependencies on it.
- Move `PklCARoots.pem` to `pkl-cli/src/certs`.
- Fix certificate related error messages that were missing an argument.
- Prevent PklBugException if initialization of `CliBaseOptions.httpClient` fails.
- Add ability to set CA certificates as a byte array
- Add CA certificates option to message passing API
* Add `--proxy` and `--no-proxy` CLI flags
* Add property `http` to `pkl:settings`
* Move `EvaluatorSettings` from `pkl:Project` to its own module and add property `http`
* Add support for proxying in server mode, and through Gradle
* Add `setProxy()` to `HttpClient`
* Add documentation
This adds changes to support loading project dependencies in non-file based projects.
The design for this feature can be found in SPICE-0005: https://github.com/apple/pkl-evolution/pull/6
Changes:
* Consider all imports prefixed with `@` as dependency notation.
* Bugfix: fix resolution of glob expressions in a local dependency.
* Adjust pkl.Project:
- Allow local dependencies from a scheme-local paths.
- Disallow certain evaluator settings if not loaded as a file-based module.
* Breaking API change: `ProjectDependenciesManager` constructor now requires `ModuleResolver` and `SecurityManager`.
This adds support for Windows.
The in-language path separator is still `/`, to ensure Pkl programs are cross-platform.
Log lines are written using CRLF endings on Windows.
Modules that are combined with `--module-output-separator` uses LF endings to ensure
consistent rendering across platforms.
`jpkl` does not work on Windows as a direct executable.
However, it can work with `java -jar jpkl`.
Additional details:
* Adjust git settings for Windows
* Add native executable for pkl cli
* Add jdk17 windows Gradle check in CI
* Adjust CI test reports to be staged within Gradle rather than by shell script.
* Fix: encode more characters that are not safe Windows paths
* Skip running tests involving symbolic links on Windows (these require administrator privileges to run).
* Introduce custom implementation of `IoUtils.relativize`
* Allow Gradle to initialize ExecutableJar `Property` values
* Add Gradle flag to enable remote JVM debugging

This changes the file paths to use characters that are safe for Windows.
Channges the output of the following:
* Package cache directory
* Generated pkl-doc files
* Kotlin generated code
Unsafe characters are encoded as (<hex>).
For example, the colon character `:` is encoded as `(3a)`.
Additionally, this changes the cache directory prefix (package-1 to
package-2).
Follows the design of https://github.com/apple/pkl-evolution/pull/3

This is a comprehensive solution to the "flaky PackageServer tests"
problem. It rules out port conflicts and imposes no limits on test
parallelism. The same solution can be used for other test servers
in the future.
Major changes:
- Turn `PackageServer` from a singleton into a class that is
instantiated per test class or test method.
- Start the server the first time its `port` property is read.
Bind the server to an ephemeral port instead of port 12110.
- For every test that uses `PackageServer`, pass the server port to
`--test-port`, `HttpClient.Builder.setTestPort`, the `CliBaseOptions`
or `ExecutorOptions` constructor, or the Gradle plugin's `testPort` property.
Wire all of these to `RequestRewritingClient`'s `testPort` constructor parameter.
- Enhance `RequestRewritingClient` to replace port 12110 with `testPort`
in request URIs unless `testPort` is -1 (its default).
- Introduce `ExecutorOptions.Builder`.
This makes executor options more comfortable to create
and allows to hide options such as `testPort`.
- Deprecate the `ExecutorOptions` constructor to steer users towards the builder.
- Get rid of `ExecutorOptions2`, which is no longer needed.
- Clean up `EmbeddedExecutorTest` with the help of the builder.
* pkl-excutor tests: symlink 0.25.0 distribution into pkl-executable/build
* Use `IoUtils.getPklHomeDir` in HttpClientBuilder
* Simplify Exceptions.java
* Enable testing for older pkl-executor distribution
Moving to java.net.http.HttpClient brings many benefits, including
HTTP/2 support and the ability to make asynchronous requests.
Major additions and changes:
- Introduce a lightweight org.pkl.core.http.HttpClient API.
This keeps some flexibility and allows to enforce behavior
such as setting the User-Agent header.
- Provide an implementation that delegates to java.net.http.HttpClient.
- Use HttpClient for all HTTP(s) requests across the codebase.
This required adding an HttpClient parameter to constructors and
factory methods of multiple classes, some of which are public APIs.
- Manage CA certificates per HTTP client instead of per JVM.
This makes it unnecessary to set JVM-wide system/security properties
and default SSLSocketFactory's.
- Add executor v2 options to the executor SPI
- Add pkl-certs as a new artifact, and remove certs from pkl-commons-cli artifact
Each HTTP client maintains its own connection pool and SSLContext.
For efficiency reasons, It's best to reuse clients whenever feasible.
To avoid memory leaks, clients are not stored in static fields.
HTTP clients are expensive to create. For this reason,
EvaluatorBuilder defaults to a "lazy" client that creates the underlying
java.net.http.HttpClient on the first send (which may never happen).
