Yike 450197e265 Export the target_required property to module-info
Some host test modules such as `python_test_host` use the
`target_required` attribute to declare target dependencies that will
be pushed to device. For example, `aidl_integration_test` references
several target dependencies in the `target_required` attribute since
those output files will be searched and pushed to device at runtime.
Besides, those target dependencies can't be declared in the `data`
attribute instead, since some modules' `data` attribute doesn't
support multi-arch.

So that, this information needs to present in module_info.json and
exported to properly generate Bazel targets that include these
dependencies.

dex_preopt_check

dex_preopt_check is a build-time check to make sure that all system server jars are dexpreopted. When the check fails, you will see the following error message:

FAILED:
build/make/core/tasks/dex_preopt_check.mk:13: warning:  Missing compilation artifacts. Dexpreopting is not working for some system server jars
Offending entries:

Possible causes are:

  1. There is an APEX/SDK mismatch. (E.g., the APEX is built from source while the SDK is built from prebuilt.)

  2. The systemserverclasspath_fragment is not added as systemserverclasspath_fragments of the corresponding apex module, or not added as exported_systemserverclasspath_fragments of the corresponding prebuilt_apex/apex_set module when building from prebuilt.

  3. The expected version of the system server java library is not preferred. (E.g., the java_import module has prefer: false when building from prebuilt.)

  4. Dexpreopting is disabled for the system server java library. This can be due to various reasons including but not limited to:

    • The java library has dex_preopt: { enabled: false } in the Android.bp file.

    • The java library is listed in DEXPREOPT_DISABLED_MODULES in a Makefile.

    • The java library is missing installable: true in the Android.bp file when building from source.

    • Sanitizer is enabled.

  5. PRODUCT_SYSTEM_SERVER_JARS, PRODUCT_APEX_SYSTEM_SERVER_JARS, PRODUCT_STANDALONE_SYSTEM_SERVER_JARS, or PRODUCT_APEX_STANDALONE_SYSTEM_SERVER_JARS has an extra entry that is not needed by the product.
