Gradle deletes all files and puts only changed files in build directory (only on exFAT fs)

[mihett05]

I've tried to build simple project with gradle on exFAT file system, after second build gradle deletes all compiled files from build/classes/java and puts only changed files. And it's impossible to run a project (referenced classes/packages not found). Gradle builds normally the same project on NTFS .

Expected Behavior

Gradle removes only files that have changed and puts changed files in build/classes directory.

Current Behavior

Gradle removes all and puts only changed files in build/classes directory.

Context

build.gradle file:

plugins {
    id 'application'
}

repositories {
    jcenter()
}

dependencies {
    testImplementation 'junit:junit:4.13'
    implementation 'com.google.guava:guava:29.0-jre'
}

application {
    mainClassName = 'org.app.App'
}

Steps to Reproduce

1. Generate project by gradle init in directory on exFAT disk.
2. Build it first time
3. Build it again
4. Look to build/classes/java directory or try to gradle run

Your Environment

File system: exFAT
OS: Windows 10 1909

Build scan URL for second gradle build: https://scans.gradle.com/s/cunw3wd2faz3e
Build scan URL for gradle run after second build: https://scans.gradle.com/s/t5tbhvxesquq6
