Objectbox-java: AGP 3.3.0 / Gradle 4.10.2 warning: API 'variant.getJavaCompile()' is obsolete and has been replaced with 'variant.getJavaCompileProvider()'.

[GerritDeMeulder]

• ObjectBox version : 2.3.1
• Reproducibility: always
• After update to Android Studio 3.3 and set android.debug.obsoleteApi=true in project gradle.properties file

Reproducing the bug

Description

Normal compilation gives this warning, after updating to android Studio 3.3.
Maybe not be high priority yet (warning says end 2019),
but since stacktrace below hints at Objectbox,
it's maybe better to keep this in mind for a next update.

WARNING:` API 'variant.getJavaCompile()' is obsolete and has been replaced with
 'variant.getJavaCompileProvider()'.
It will be removed at the end of 2019.

When you put android.debug.obsoleteApi=true in project gradle.properties file ,
stacktrace hints at Objectbox ObjectBoxAndroidTransform kotlin file:

Thanks for reporting! We are already aware of this and have an issue for this internally.

As you said, it is safe to ignore the warning and ObjectBox will continue to work fine.

We should be able to get a version out before end of 2019 to avoid this warning. ;)

We just did a silent release of 2.3.2 which uses the new Android Gradle Plugin 3.3.0 APIs and no longer triggers this warning.

[GerritDeMeulder]

Good, that issue is indeed resolved.
But it looks like the recent Gradle changes have not gotten you in calm waters yet :
Don't know if following annotation / incremental compilation is worth a separate issue or not (and both Google /Gradle already classify this issue as resolved :( :

"Gradle may disable incremental compilation as the following annotation processors are not incremental: objectbox-processor-2.3.2.jar (io.objectbox:objectbox-processor:2.3.2).
Consider setting the experimental feature flag android.enableSeparateAnnotationProcessing=true in the gradle.properties file to run annotation processing in a separate task and make compilation incremental."
