Building for Desktop on GNU/Linux fails with `Define a valid SDK location with an ANDROID_HOME environment variable` or `Declaring 'crunchPngs' as a property [...] on com.android.build.gradle.internal.dsl.BuildType$AgpDecorated has been deprecated.`.

Ahoj,

I am trying to build the desktop app from the latest git checkout from this repository on Artix GNU/Linux (rolling release).

• When I build with system installed gradle version 9.5.1 an Java version OpenJDK 26.0.1 (using gradle instead of ./gradlew), building :app fails with

• When using ./gradlew clean build, it fails with

FAILURE: Build failed with an exception.

* What went wrong:
26.0.1

• When I additionally manually install old version of Java JDK, jdk21-openjdk version 21.0.11.u10, and make that my default Java, then it fails with

FAILURE: Build failed with an exception.

* What went wrong:
Could not determine the dependencies of task ':app:compileDebugJavaWithJavac'.
> SDK location not found. Define a valid SDK location with an ANDROID_HOME environment variable or by setting the sdk.dir path in your project's local properties file at '/var/cache/makepkg/build/bruce-app-git/src/bruce-app/local.properties'.

More verbose build log (executing ./gradlew -PreleaseBuild=true --no-daemon -console verbose --info --no-parallel clean build and capturing the terminal output -- note that the error just reported above also happens without all those command line options, also without -PreleaseBuild=true):

gradle-build.log

Seems that, contrary to what the README.md says, it cannot be built for on non-Android desktop.

Regards!
