Support Gradle Configuration Caching

[ZacSweers]

@fractalwrench and I talked about this offline, filing to track here!

I think this is done now but will let y'all make the final call on closing 👍

Did this support regress since 2020? It doesn't appear to work on 7.2.0 com.bugsnag:bugsnag-android-gradle-plugin:7.2.0

HI @Naitbit,

There are still some parts of the plugin that do not support configuration caching. This is still on our backlog to address but I'm afraid I don't have any further updates at this time

[hackertronix]

@yousif-bugsnag do you have an approximate timeline for when this would be prioritized maybe?

[abigailbramble]

Hi @hackertronix - unfortunately we do not have any further updates at this time. We'll look into this when priorities allow.

[ZacSweers]

Would you be open to a community-contributed PR?

[lemnik]

As of v7.3.0 we have support for Gradle Configuration Caching for our ProGuard (R8) support (but not NDK just yet), we're still working on adding support for our other tasks.

[ZacSweers]

FYI it looks like this has regressed in 7.4.0 as NdkToolchain.baseDir is incorrectly annotated as a Property<File> rather than a DirectoryProperty. Will send a PR, but it would be helpful if some tests could be added that ensured configuration cache didn't regress.

Thanks @ZacSweers, we will look into this asap.

With Gradle 8.1, its failing with

external process started 'git --version' 
See https://docs.gradle.org/8.1/userguide/configuration_cache.html#config_cache:requirements:external_processes

due to the following external process execution https://github.com/bugsnag/bugsnag-android-gradle-plugin/blob/908e6186bff7badf24ee214c852599b26f71abb9/src/main/kotlin/com/bugsnag/android/gradle/BugsnagReleasesTask.kt#L140

[johnkiely1]

Hi @rohilchodankar Thanks for raising, we are investigating this now.

[johnkiely1]

Hey @rohilchodankar, our latest version v8.0.1 has just been released. This should address the issues you were seeing with Gradle 8.1.
