`sandboxSuffix` is empty string when copying files inside the `prepareSandbox {}` task

[hsz]

It is possible to achieve it with:

val runIdeWithPlugins by intellijPlatformTesting.runIde.registering {
    plugins {
        plugin("com.google.ide-perf:1.3.1")
    }

    prepareSandboxTask {
        dependsOn("downloadAptosBinaries")
        from("${rootDir}/cert") {
            into(intellijPlatform.projectName.map { "$it/bin" })
            include("**")
        }
    }
}

To make it more transparent, I've introduced the projectName property (39161c0), so with the next release, you'll be able to:

val runIdeWithPlugins by intellijPlatformTesting.runIde.registering {
    // ...

    prepareSandboxTask {
        // ...

        from("${rootDir}/cert") {
            into(pluginName.map { "$it/bin" })
        }
    }
}

I tried to specify prepareSandboxTask {} configuration inside the runIdeWithPlugins task, and this indeed works, there's no need for the intellijPlatform.projectName (sandboxSuffix has the expected value of _runIdeWithPlugins, and the pluginName exists in my environment anyway). I'm going to extract the common copying code into the function and call it twice from inside the runIdeWithPlugins and from the general prepareSandboxTask checking for the existence of the directory.

I want to clarify that my problem is not fixed with the intellijPlatform.projectName. I need to patch prepareSandboxTask both for buildPlugin and for runIde, so in general case patching it inside the custom task does not work.

My understanding is that there's some special case code inside the gradle plugin, that creates the prepareSandboxTask_runIdeWithPlugins custom task specifically for my runIdeWithPlugins custom task, and it executes the body of the

    prepareSandboxTask {
        from("${rootDir}/cert") {
            into(intellijPlatform.projectName.map { "$it/bin" })
            include("**")
        }
    }

(which is defined outside the custom task as it's shared for the deployment and for testing). And the bug report is that sandboxSuffix (or sandboxPluginsDirectory for that matter) is not populated correctly at the time of execution of the body of that prepareSandboxTask_runIdeWithPlugins.

UPD.
Ok, I think I just might be doing it incorrectly. It seems I can't really patch generated prepareSandboxTask_runIdeWithPlugins with the root level

tasks {
    prepareSandboxTask {
    
    }
}

at all, it's never called. So to provide binaries both to the buildPlugin and to runIde I need to use two blocks of prepareSandboxTask. Is that right?
