For other people who wonder why apply(from - "../jacoco.gradle.kts") doesn't work, check this article - https://medium.com/@kurtlemond/migrating-jacoco-reports-gradle-tasks-to-kotlin-dsl-7b566d89ea92
TLDR: Dynamic resolution, which Groovy DSL provides, does not exists in Kotlin DSL.
I ended up using "Precompiled Script Plugin".
I just added kotlin-dsl-precompiled-script-plugins
to buildSrc/build.gradle.kts and created jacoco-reports.gradle.kts under buildSrc/src/main/kotlin folder. Then you can add id("jacoco-reports") plugin to your modules.
@DenisShov other solution would be to revert jacoco.gradle.kts to groovy right ?

@ThomasGoehringer @agustinsivoplas yes it is working then but since i have multiple modules there will be lot of duplicate code so i want to have it common place
