[Linux] Can't build Android

[alchem1ster]

Self help steps before reporting the issue:

• Check Solar2D forums for a solution
• If Android: make sure Java8 is installed and reported when running java -version and javac -version if not, download and install Java 8

Before reporting
Install Solar2D today with snap file from Releases. Tried to build a demo project and got build error.

Platforms involved
Building on: Pop!_OS 22.04 LTS x64

Welcome to Gradle 7.5!

Here are the highlights of this release:
 - Support for Java 18
 - Support for building with Groovy 4
 - Much more responsive continuous builds
 - Improved diagnostics for dependency resolution

For more details see https://docs.gradle.org/7.5/release-notes.html

To honour the JVM settings for this build a single-use Daemon process will be forked. See https://docs.gradle.org/7.5/userguide/gradle_daemon.html#sec:disabling_the_daemon.
Daemon will be stopped at the end of the build

Deprecated Gradle features were used in this build, making it incompatible with Gradle 8.0.

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

Incompatible because this component declares an API of a component compatible with Java 11 and the consumer needed a runtime of a component compatible with Java 8

Try using JDK 11+.
The issue template may misleading.

The same issue. Maybe need to upgrade Java SDK inside snap? But how?

[clang-clang-clang]

Sorry I can't access linux right now and I'm not sure if this will fix the problem.

Can you export JAVA_HOME for your JDK installation location on your terminal, then set jdk/bin to PATH and try to open solar2d from the terminal?

It looks something like this:

# setup variable for current terminal
$ export JAVA_HOME=/somewhere/jdk11
$ export PATH=$JAVA_HOME/bin:$PATH
# start with above variables
$ solar2d

If the above settings do not build Android properly, we need to wait for the engine core to modify the JDK version on which it depends.

The same. I think that need to update sdk inside Snap filesystem, because in log:

Detected Java version: 1.6 in: /snap/solar2d/x1/usr/lib/jvm/java-8-openjdk-amd64/jre

It doesn't use Java from the system :(
