ClassNotFoundException when running testIde with a different IDE version

[chylex]

What happened?

I tried to add a task that runs tests in the latest EAP version:

tasks.withType<Test>().configureEach {
	useJUnitPlatform()
}

val testSnapshot by intellijPlatformTesting.testIde.registering {
	version = "LATEST-EAP-SNAPSHOT"
	useInstaller = false
}

Running the task fails with ClassNotFoundException.

• With IU and LATEST-EAP-SNAPSHOT, it cannot find MultiRoutingFileSystemProvider.
• With IC and LATEST-EAP-SNAPSHOT, it cannot find CoreBootstrapSecurityManager.
• If I change the task's version to 2024.3.1, with or without useInstaller, I get the same error as with LATEST-EAP-SNAPSHOT.
• If I remove the task's custom version, so it uses the project's default (IU and 2023.3.3), it works.
