I tried install Lavalink on my project container but i get this error about the java version. It’s possible to update java?

Exception in thread "main" java.lang.UnsupportedClassVersionError: lavalink/server/Launcher has been compiled by a more recent version of the Java Runtime (class f

Right now, it’s a big deal for us to update things in the OS image like Java. We’re waiting on a feature from AWS/Terraform that will make that much easier, so this probably won’t happen until the feature is released. Is it possible for you to build Lavalink with an older version of Java? Then it would run on the current setup.

In case you’re still trying to get this possible, it’s possible to use the build artifacts from previous revisions instead. v2.2 is available at https://ci.fredboat.com/viewLog.html?buildId=4831&buildTypeId=Lavalink_Build&tab=artifacts , and works fine for me (Though unsurprisingly there are issues with websocket permissions)

You can use a wget from the console to get the files into your project

When Would Java Be Updated?

We don’t have a specific timeframe. We’re waiting on a feature from AWS/Terraform that will make that much easier, and this won’t happen until the feature is released.
