Kotlin DSL unresolved references on Windows

[fabianishere]

Hi, I have observed an issue with Gradle (6.2 and 6.2.2) where the compilation of Kotlin files in buildSrc fail with unresolved references on Windows due to CRLF line endings. When using LF line endings instead, the compilation is successful and the build succeeds.

The error I am getting:

Starting a Gradle Daemon (subsequent builds will be faster)

> Task :buildSrc:generateExternalPluginSpecBuilders
> Task :buildSrc:compilePluginsBlocks

e: D:\a\gradle-kotlin-dsl-bug\gradle-kotlin-dsl-bug\buildSrc\src\main\kotlin\project-convention.gradle.kts: (13, 5): Unresolved reference: reports

Expected Behavior

buildSrc should build and the build should succeed.

Current Behavior

Kotlin compilation of buildSrc fails with unresolved references on Windows when using CRLF line endings.

Steps to Reproduce

See this repository to reproduce the error: https://github.com/fabianishere/gradle-kotlin-dsl-bug
I have also configured Github Actions to build the repository on Windows and Ubuntu, which shows the error on Windows: https://github.com/fabianishere/gradle-kotlin-dsl-bug/actions/runs/56738261

I currently work around this issue by forcing the *.gradle.kts files in buildSrc/src to use LF line ending in .gitattributes:

# Gradle does not buils when this file uses CRLF
buildSrc/src/main/kotlin/project-convention.gradle.kts  text eol=lf

Hi @fabianishere,

The issue has been fixed in Gradle 6.3-rc-1.
