# `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.)



1.  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.



1.  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.)



1.  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.



1.  `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.
