TLDR: Attempting to run startupBenchmark tests on emulator with api 33 (had a similar dropShader error on physical device so using emulator). Looks like shell command is missing an argument

Component used:

benchmarkRule.measureRepeated(
        packageName = "com.myApp",
        metrics = listOf(StartupTimingMetric()),
        iterations = 10,
        compilationMode = compilationMode, // occurs on full, none, and partial
        startupMode = StartupMode.COLD

Version used:

profileinstaller:1.3.0-rc01

benchmark-macro-junit4:1.2.0-alpha11

Devices/Android versions reproduced on: Emulator - api 33

If this is a bug in the library, we would appreciate if you could attach:

Sample project to trigger the issue.
A screenrecord or screenshots showing the issue (if UI related).

log output:

java.lang.IllegalStateException: Expected no stdout/stderr from find /data/user_de/0/[com.MyApp]/code_cache -type f | xargs rm, saw Output(stdout=, stderr=rm: Needs 1 argument (see "rm --help"))

function in question:

public fun dropShaderCache() {
        Log.d(TAG, "Dropping shader cache for $packageName")
        val dropError = ProfileInstallBroadcast.dropShaderCache(packageName)
        if (dropError != null) {
            if (Shell.isSessionRooted()) {
                // fall back to root approach
                val path = getShaderCachePath(packageName)
                Shell.executeScriptSilent("find $path -type f | xargs rm")
            } else {
                throw IllegalStateException(dropError)
            }
        }
    }
