Steps to reproduce:

1. Configure execution profile for R8 and run it in separate process:

android {
    execution {
        profiles {
            create("separate") {
                r8 {
                    jvmOptions += "-Xmx3G -Xms3G".split(" ")
                    runInSeparateProcess = true
                }
            }
            create("inside") {
                r8.runInSeparateProcess = false
            }
        }
        defaultProfile = "separate"
    }
}

2. Specify whyareyounotinlining option in proguard config
3. Enable this option by specifying system property in gradle.properties:

systemProp.com.android.tools.r8.experimental.enablewhyareyounotinlining=1

Sample project is attached.

Actual behavior

When R8 runs inside the main Gradle Daemon process, the system property works correctly and build finishes successfully. When R8 runs outside the process, the build failes with:

Caused by: com.android.tools.r8.internal.g: Unknown option "-whyareyounotinlining"

As I understand, the option systemProp.com.android.tools.r8.experimental.enablewhyareyounotinlining=1 wasn't passed to forked process.

Environment:

Gradle version: 8.10.2 AGP version: 8.7.2
