@fruitywelsh: The fix for this problem is to run

archlinux-java set java-11-openjdk

I've added a pgp signature to the source file, to import the signing key, run the following command:
> gpg --recv-keys FA10826A74907F9EC6BBB7FC2BA2CD21B5B09570

I now realised, the pinned comment solves my issue. :D However, I have a new issue now. After many successful compilations I get the following error:

Same problem as rixx here.

I started to get failing buildings with the error:

* What went wrong:
Execution failed for task ':compileJava'.
> Could not target platform: 'Java SE 11' using tool chain: 'JDK 8 (1.8)'.

I was able to get a successful build in my owned cloned git and install by setting: export JAVA_HOME="/usr/lib/jvm/java-11-openjdk" export PATH="${JAVA_HOME}/bin:${PATH}"

and installing it manually as described in the README

Adding these to lines to lines 29 and 30 in PKGBUILD, succeeds in building, but gives errors when trying to run the command:

Error: A JNI error has occurred, please check your installation and try again
Exception in thread "main" java.lang.UnsupportedClassVersionError: org/asamk/signal/Main has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0

        at sun.misc.Launcher$AppClassLoader.loadClass(
        at java.lang.ClassLoader.loadClass(
        at sun.launcher.LauncherHelper.checkAndLoadMain(

These errors persists even if my env includes the modified JAVA_HOME and PATH

Sorry if this is wrong place to put this, hope this is useful :)

I can' import the signing key:

> gpg --recv-keys FA10826A74907F9EC6BBB7FC2BA2CD21B5B09570
gpg: keyserver receive failed: General error

Edit: it worked like this:

gpg --keyserver --recv-key FA10826A74907F9EC6BBB7FC2BA2CD21B5B09570

Running signal-cli -u '+XXXXXXXXXXX' daemon fails with error Missing native library dependency for dbus service: could not load FFI provider jnr.ffi.provider.jffi.Provider

Rebuilding and reinstalling signal-cli doesn't fix the issue.

May it be caused by today's update: libelf (0.178-2 -> 0.179-1)?

UPD: Or maybe by this one: glib2 (2.64.2-1 -> 2.64.3-1)?

@pmav99 the build also works with java-8-openjdk but you need the JDK package installed as well (jdk8-openjdk), not just the JRE package (jre8-openjdk)

pmav99 commented on 2020-03-21 11:03

For the record, I just tried to compile with java-8-openjdk/jre and it failed. After switching to java-11-openjdk it compiled correctly.

The error was:

Execution failed for task ':compileJava'.

Could not find tools.jar. Please check that /usr/lib/jvm/java-8-openjdk/jre contains a valid JDK installation.
