[Bug]: Compile error when building with prodRelease

[misaochan]

Summary

Building the 4.0-release branch with the prodRelease build variant encounters an error as of today (24 May). It did not encounter any errors the last time I did it (about 2 weeks ago), hence the issue probably lies with a deprecation or changes to the relevant external library.

Commenting out the line implementation("io.github.coordinates2country:coordinates2country-android:1.2") { exclude group: 'com.google.android', module: 'android' } in build.gradle solves the compile error, but might introduce other issues.

Steps to reproduce

Build the 4.0-release branch with the prodRelease build variant. Do not test with prodDebug, this does not run minifyWithProguard and therefore does not cause the same issue.

Expected behaviour

@misaochan Did you try after deleting the cached packages and build folder?

[misaochan]

Yes, doesn't solve the issue. :/

Hi @nicolas-raoul , any thoughts on what the issue could be? As you appear to be the author of https://github.com/coordinates2country/coordinates2country-android :)

[nicolas-raoul]

I can reproduce the issue.

I built that library using openjdk 11.0.12 2021-07-20 LTS or earlier.

If there is anything I can change on the library side to fix it, I am happy to do it. :-)
