A modern programming language that makes developers happier.

kotlinlang

I successfully upgraded my project to Kotlin 1.6.21, but after changing `plugins { id "org.jetbrains.kotlin.jvm" version "1.6.0" }` to `plugins { id "org.jetbrains.kotlin.jvm" version "1.6.21" }` I now get: "DefaultTaskContainer#register(String, Class, Object...) on task set cannot be executed in the current context." This is with Gradle 6.9.2. Any idea what I'm doing wrong?

Sure. Line 713 in my `build.gradle` is:
```   161  subprojects { subproject -&gt;
   162
   163      if (name in excludedProjectNames) {
   164          // skip applying 'gradle' plugins
   165          // to avoid the creation of empty jars
   166          return
   167      }
   168
   169      apply plugin: 'java-library'
   170      apply plugin: 'eclipse'
   171      apply plugin: 'maven'
   172      apply plugin: 'jacoco'
   173      apply plugin: 'org.jetbrains.kotlin.jvm'
   174      apply plugin: 'org.jlleitschuh.gradle.ktlint'
   175      apply plugin: 'io.gitlab.arturbosch.detekt'```

and `settings.gradle` contains:
```    1  pluginManagement {
     2      repositories {
     3          gradlePluginPortal()
     4          maven {
     5              name "ext-release-local"
     6              url "<https://artifactory.rnd.metricstream.com/artifactory/ext-release-local>"
     7          }
     8      }
     9
    10      plugins {
    11          id "com.gradle.enterprise" version "3.7.1"
    12          id "org.sonarqube" version "2.8"
    13          id "de.fayard.buildSrcVersions" version "0.7.0"
    14          //id "com.palantir.jacoco-full-report" version "0.4.0"
    15          id "com.github.voplex95.lesscompiler" version "1.0.3"
    16          id "com.moowork.node" version "1.1.1"
    17          id "com.moowork.grunt" version "1.2.0"
    18          id "com.bmuschko.cargo" version "2.1"
    19          id "org.jetbrains.kotlin.jvm" version "1.6.21"
    20          id "org.jlleitschuh.gradle.ktlint" version "9.4.1"
    21          id "io.gitlab.arturbosch.detekt" version "1.16.0"
    22          id 'net.ltgt.errorprone' version "1.2.1"
    23          id "nebula.lint" version "17.1.0"
    24      }
    25  }
    26```

Could you try with just released KGP version `1.7.0-Beta` and if it is still failing - open a new issue with repro?

It works with `id "org.jetbrains.kotlin.jvm" version "1.7.0-Beta"` .  However, I cannot use beta versions right now. So should I stick with `1.6.0` for the time? What are the downsides of using plugin `1.6.0` with version `1.6.21` for the rest (stdlib, embeddable-compiler, reflect, ...)?

yep, then just stick with `1.6.0`. We would not release `1.6.22` version, so you have to wait for final `1.7.0` release

&gt; What are the downsides of using plugin `1.6.0` with version `1.6.21` for the rest (stdlib, embeddable-compiler, reflect, ...)?
Theoretically should be no downsides or issues

I will quote you on that :slightly_smiling_face:

thx for your help.  BTW: I was not able to find the `1.7.0-Beta` tag in github (was curious to compare the 2 versions)

release is still in the progress. Should appear soon
