I tried changing gradlePluginPortal to mavenCentral , works a little bit, but then fails with:

- Gradle Core Plugins (plugin is not in 'org.gradle' namespace)
- Plugin Repositories (could not resolve plugin artifact 'org.jetbrains.kotlin.jvm:org.jetbrains.kotlin.jvm.gradle.plugin:1.5.21')
  Searched in the following repositories:
    MavenLocal(file:/home/arian/.m2/repository/)
    MavenRepo
