Arch Linux User Repository

I've added a pgp signature to the source file, to import the signing key, run the following command:

gpg --keyserver hkps://keys.openpgp.org --recv-keys FA10826A74907F9EC6BBB7FC2BA2CD21B5B09570

in case of

Gradle requires JVM 17 or later to run. Your build is currently configured to use JVM 8.

show available java versions archlinux-java status, then set latest as default: sudo archlinux-java set java-26-openjdk

confirm change with java -version, then it worked for me.

@fow0ryl and @balwierz You need Java 25

For anyone else like me failing to build this: try a fresh build of libsignal-client first :)

This package still downloads (lots of) stuff during build().

This should not happen; prepare() is to be used to get the sources ready so that a build can occur even in an offline environment.

So, please do the preparations in prepare().

With jdk23-openjdk (currently up to date provider of make dependency java-environment), it fails to build (see below).

With jdk21-openjdk (java-environment=21) it builds.

So, please specify a versioned dependency in the makedepends.

Regards!

Deprecated Gradle features were used in this build, making it incompatible with Gradle 9.0.

You can use '--warning-mode all' to show the individual deprecation warnings and determine if they come from your own scripts or plugins.

For more on this, please refer to https://docs.gradle.org/8.6/userguide/command_line_interface.html#sec:command_line_warnings in the Gradle documentation.
