* If a KotlinGradleSubplugin implements
KotlinCompilerPluginSupportPlugin, don't apply it as a legacy plugin
* Add the legacy KotlinGradleSubplugin implementations back so that
when there's JAR hell with META-INF/services in the old artifacts
pointing to the classes, loading the plugins with ServiceLoader (legacy
implementation) from the new artifacts would not fail.
* There's a corner case for plugins not in kotlin-gradle-plugin
If a newer and older version of such a subplugin is used with an older
version of the Kotlin Gradle plugin, the latter will find the META-INF
entries and will try to load the subplugins from the new version. With
the original fix for KT-39809, this would result in silently ignored
empty stub implementations.
Given that the Kotlin Gradle plugin can now check if a subplugin
supports the new API, it's OK to keep the old entries and make the
stub implementations throw a build error when called, so that improper
plugin versions are not ignored and are clearly reported.
Note that this is only necessary for the subplugins not bundled in the
kotlin-gradle-plugin module, as those will always be in sync with the
Kotlin version.
Issue #KT-39809 Fixed
To simplify configuring a `KotlinCompilation` with Gradle Kotlin DSL, it
is essential to expose statically-known types where possible.
This commit parametrizes `KotlinCompilation` with its Kotlin options
type (a subtype of `KotlinCommonOptions`) and adds `kotlinOptions` and
`compileKotlinTask` to `KotlinCompilation`.
(minor) Also reduce the visibility of `attachClassesDir` and
`setupPlugins` to internal, since this API is not for external use.
Add default implementations for KotlinTarget and KotlinCompilation
(some of them are used in code added by further commits).
Refactor AbstractKotlinPlugin so that parts of its logic can be easily
applied outside the plugin (needed for MPP plugin later).
The single platform Kotlin plugins having Kotlin compiled along with
Java will now create a KotlinCompilation and a KotlinSourceSet per Java
source set or per Android variant.
The build configuration logic will use KotlinCompilation
objects rather than Java or Android plugin entities.
Subplugins API and implementations are updated to use KotlinCompilation.
Introduce Gradle models for plugins 'kotlin-allopen', 'kotlin-noarg' and
'kotlin-sam-with-receiver'. Corresponding model builders are registered
in each one of those plugin main classes.
Added .property files to make the plugins available by fqnames in
order to publish them to Gradle Plugin Portal.
