Precompiled script plugin fails to build on Windows if script is saved with CRLF (accessors not resolved)

[vlsi]

Expected Behavior

The precompiled script plugin should compile on all major platforms no matter which ends of lines the file has.

Current Behavior

If my-plugin.gradle.kts is saved with CRLF ends-of-lines, the plugin can't be compiled on Windows.

This sounds super strange, but I can reproduce it reliably.

The workaround is to ensure .gradle.kts is saved with LF, so I add src/main/kotlin/**/*.gradle.kts text eol=lf to my .gitignore.

Context

I want to split build logic to a precompiled plugin, however, it leads to an extremely hard to understand failure :(

Steps to Reproduce

Note: it requires Windows. I can't reproduce the failure in my macOS.

build.gradle.kts:

plugins {
    `kotlin-dsl`
}

repositories {
    mavenCentral()
}

configure<KotlinDslPluginOptions> {
    experimentalWarning.set(false)
}

src\main\kotlin\my-plugin.gradle.kts:

plugins {
    `java-library`
}

// compileJava is a generated accessor
// However, Gradle fails to resolve it if .gradle.kts is written with CRLF end-of-lines :(
tasks.compileJava {
}

gradlew.bat build:

\src\main\kotlin\my-plugin.gradle.kts: (5, 7): Unresolved reference: compileJava
...
FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':compileKotlin'.
> Compilation error. See log for more details

Your Environment

Gradle 6.1.1

Sample failure in GitHub Actions (note that both Linux and macOS builds work there, while Windows fails to build buildSrc): https://github.com/weisJ/darklaf/runs/448020434?check_suite_focus=true#step:4:26

I've been seeing weird errors with precompiled script plugins on one (Windows) machine since Gradle 6.1. This seems to be what was causing it. Doesn't happen with 6.0.1. Glad to finally understand what was happening!
