IJ 2026.1.2 [UNRESOLVED_IMPORT] Unresolved reference 'execution'

IntelliJ Platform
1

With the following configuration

dependencies {
    intellijPlatform {
        intellijIdea("2026.1.2") // Unresolved reference 'GradleRunConfiguration'. [and more...]
        // intellijIdea("2025.3.6") // this works

        bundledPlugin("org.jetbrains.kotlin")
        bundledPlugin("org.jetbrains.plugins.gradle")

        compatiblePlugin("org.jetbrains.android")
        compatiblePlugin("intellij.webp")

        testFramework(TestFrameworkType.Platform)
    }
}

I’m seeing

[UNRESOLVED_IMPORT] Unresolved reference 'execution'.

on the line

import org.jetbrains.plugins.gradle.service.execution.GradleRunConfiguration

while everything worked fine with previous IJ releases up to 2025.3.6.

How could that be worked around / fixed?

[EDIT: Problem persists with IntelliJ IDEA 2026.2 EAP 5 (262.7132.23 build)]
