1. Use 'KaptOptions' for all kapt options, including paths and flags.
2. Use a single 'KAPT_OPTIONS' compiler configuration key for setting all options (using a mutable KaptOptions.Builder).
3. Pass 'KaptOptions' instead of separate flags.
4. Remove 'KaptPaths'.
5. Remove deprecated 'aptOnly' CLI option.
since it causes numerous classloading issues. Using the wrapping types
and reload them in the proper context when needed.
Note: this version supports only classes, but the wrapping type could
be extended to support other types in the future.
+ numerous fixes related to proper loading and handling of the templates.
Friend modules should be provided using the -Xfriend-modules flag
in the same format as -libraries. No manual configuration required for
JPS, Gradle and Maven plugins.
Friend modules could be switched off using the -Xfriend-modules-disabled
flag. Doing that will
* prevent internal declarations from being exported,
* values provided by -Xfriend-modules ignored,
* raise a compilation error on attemps to use internal declarations from other modules
Fixes #KT-15135 and #KT-16568.
- Display the Kotlin version in kotlin-gradle-plugin. This is needed
because if "-version" is specified in compiler arguments, the "info"
level of the message printed by the compiler in CLICompiler prevents
it from being displayed by default (unless "--debug" is passed to
Gradle).
- Display the version of JRE the compiler is running on. This will be
helpful to diagnose Java 9 related issues in the future.
- In CLI, also display the executable name (kotlinc-jvm or kotlinc-js)
Introduce system property kotlin.compiler.X.enable.idea.logger=true
The reason is that I suspect that the error is somewhere at com.intellij.ide.plugins.PluginManagerCore#loadDescriptorFromJar but unfortunately default logger doesn't log messages at "info" log level so we can't see why exactly does it fail.
Users can enable IDEA's logger to see more details.
#KT-11916 fixed
To use the IC either:
1. set the `kotlin.compiler.incremental` property to `true` in a pom.xml:
```
<properties>
<kotlin.compiler.incremental>true</kotlin.compiler.incremental>
</properties>
```
2. pass the `kotlin.compiler.incremental` property in a command line:
```
mvn install -Dkotlin.compiler.incremental=true
```
When IC is on Kotlin plugin is expected to print the warning in the log:
```
Using experimental Kotlin incremental compilation
```
After each call an incremental compiler will also log how many files it has compiled:
```
Compiled %SOME_NUMBER% Kotlin files using incremental compiler
```
Note that the first build will be non-incremental.
For more diagnostic information (such as an exact list of compiled files) use the `kotlin.compiler.incremental.log.level` system property:
```
mvn install -Dkotlin.compiler.incremental=true -Dkotlin.compiler.incremental.log.level=info
```
To force the rebuild just run the 'clean' goal:
```
mvn clean install
```
