This change adds a Soong module that stores the paths to the compilation artifacts of system server jars in a variable, which will then be consumed by Make to check if the artifacts are installed. When the check fails, it means that dexpreopting is not working for some system server jars and needs to be fixed. Bug: 201371822 Test: m nothing Test: manual - 1. Add "service-permission" to DEXPREOPT_DISABLED_MODULES (https://cs.android.com/android/platform/superproject/+/master:build/make/core/product_config.mk?q=DEXPREOPT_DISABLED_MODULES) 2. m nothing 3. See the error: Missing compilation artifacts. Dexpreopting is not working for some system server jars Offending entries: system/framework/oat/x86_64/apex@com.android.permission@javalib@service-permission.jar@classes.odex system/framework/oat/x86_64/apex@com.android.permission@javalib@service-permission.jar@classes.vdex Change-Id: I4816f19668f1dae180a34adafdbfa448c97aa0db
