0.14: Cannot compile java part without android sdk

[bratkartoffel]

Hi there,

starting with 0.14 release I cannot compile the java without the android sdk:

[libsignal-client-0.14.0/java] $> ./gradlew compileJava
Downloading https://services.gradle.org/distributions/gradle-7.4-bin.zip
..............................................................................................................

Welcome to Gradle 7.4!

Here are the highlights of this release:
 - Aggregated test and JaCoCo reports
 - Marking additional test source directories as tests in IntelliJ
 - Support for Adoptium JDKs in Java toolchains

For more details see https://docs.gradle.org/7.4/release-notes.html

To honour the JVM settings for this build a single-use Daemon process will be forked. See https://docs.gradle.org/7.4/userguide/gradle_daemon.html#sec:disabling_the_daemon.
Daemon will be stopped at the end of the build

How can I disable the android stuff without modifying the settings.gradle?

Thanks!

Instead of using the top-level compileJava task, you should specifically use the tasks in the client sub-project, e.g. client:build or client:compileJava. (You probably don't need the server project artifacts either.)

That does work, at least when using jdk11+ to compile the code. When using java 8, the build fails with another error:

[libsignal-client-0.14.0/java] $> ./gradlew :client:jar

As the compile target for the source is Java 8, I think it should also compile using that JDK.

A reasonable request! Incorporated into the just-tagged v0.15.0.
