1.5.21-1.0.0-beta06

Highlights

• Supported finer-grained tracking of changes in classpath / different modules for incremental processing. Previously, whenever there was a change in the classpath, a full reprocessing would be triggered. Now only dirty classes that are reachable will invalidate sources. This is disabled by default, however. Please enable it by setting the Gradle property ksp.incremental.intermodule=true.
• Supported default values in annotations.
• Supported checked exceptions in compiled classes.
• Supported processing without Kotlin sources.

Issues Resolved
#53 Annotation values that are default are not visible in KSP
#233 Incremental processing for classpath changes
#493 Code does not get generated if project has only Java source files
#496 Execution failed for task ':foo:kspKotlin'. > Extension of type 'KspExtension' does not exist.
#507 getJvmCheckedException does not work for already compiled files
#511 About incremental aggregating processor
#531 The AbstractCompile.destinationDir property has been deprecated. This is scheduled to be removed in Gradle 8.0.

1.5.21-1.0.0-beta05

Highlights

• updated kotlin version to 1.5.21
• fixed a bug in findDeclaration() for Java Enum entry value
• added Resolver.getJvmCheckedException for property accessors

1.5.20-1.0.0-beta04

Fixes #487 KspTask.configure()'s @internal annotation is incompatible with Gradle 7.x.

1.5.20-1.0.0-beta03

Highlights

Updated to Kotlin 1.5.20
Experimental support of KMP (JVM, JS and Metadata)
KSNode.validate now doesn’t validate local declarations by default.

Bug fixes

#448 Not compatible with gradle configuration cache
#464 Generated proguard files in resources are not seen by AGP

1.5.10-1.0.0-beta02

Highlights

• fixed an issue with asMemberOf when calling with a Java property accessor.
• Added back fun interface for SymbolProcessorProvider.

1.5.10-1.0.0-beta01

Highlights

• Updated to Kotlin 1.5.10
• Introduced KSPropertyDeclaration.hasBackingField

API and Behavior Changes

• Parameters of SymbolProcessorProvider.create() are refactored into SymbolProcessorEnvironment
• Name of default package (i.e., w.o. package declaration) is changed to an empty string.
• The deprecated SymbolProcessor.init() is removed.

1.5.0-1.0.0-alpha10

Highlights

• switch to Sequence for a bunch of APIs
  • Some of the API return type has been changed from Collection or List to Sequence, which will allow performance improvement if you use case involved early termination.
  • Note that because Sequence is lazily evaluated, it requires a terminal operation to make actual compute happen. Please check you uses around the impacted APIs to see if they have a terminal operation. Most common use case is Collection.map{} which will iterate through the collection by itself, but is non-terminal for Sequence and should be companied with toList() or replaced with forEach
  • For the whole list of APIs impacted by this change, please refer to this commit.
• Added KSDeclaration.getDocString() API for getting the document comment. Note that it returns as is and you might need to process the string.
• Origin for KS symbols from binaries is now split into KOTLIN_LIB and JAVA_LIB.
• Added name mapping helper for mapping names from Kotlin to Java and Java to Kotlin.
• asMemberOf() is now a member function of KSPropertyDeclaration and KSFunctionDeclaration, instead of Resolver
• Add KSType.outerType and KSType.innerArguments
• Introduce KSType.isFunctionType and KSType.isSuspendFunctionType

Hightlights

New Entry Point

A new interface, SymbolProcessorProvider is introduced to replace SymbolProcessor.init().
Previously, processors implements SymbolProcessor and register themselves

1. in META-INF/services/com.google.devtools.ksp.processing.SymbolProcessor, and
2. need to save the environment / utils passed to SymbolProcessor.init().

Now, processors should implement and register the new provider interface SymbolProcessorProvider,

1. in META-INF/services/com.google.devtools.ksp.processing.SymbolProcessorProvider, and
2. create an instance of the old SymbolProcessor, where the utils / environment can be passed in the constructor.

So that processors can get rid of lateinit vars for those environments and utils.

The old service SymbolProcessor is still loaded from its service file. However, if the processor register both SymbolProcessor and SymbolProcessorProvider, and the provider returns exactly the processor registered, then the processor's init() will be called twice.

We recommend migrating to the new interface and are planning the deprecate the old service and SymbolProcessor.init().

Thanks @edrd-f for this new interface!

1.4.32-1.0.0-alpha07

Highlights

• Updated Kotlin version to 1.4.32
• Added Resolver.getDeclarationsFromPackage() API, this API is to retrieve declarations with a given package name from both classpath and sources. Note that this API can be expensive.
• Bug fixes around generic type arguments and jvm_static detection.
