Kivy build fails on JDK 12

[zurgeg]

Versions

• Python: 3.7
• OS: Mac OS Mojave
• Buildozer: I don't know

Description

I attempted to run Buildozer's andriod build system until i ran into an error. I have no idea how to fix this.

Command:

buildozer -v android debug

#    You can define all the "list" as [section:key].

#    Let's take [app] / source.exclude_patterns.
#    Instead of doing:
#
#[app]
#source.exclude_patterns = license,data/audio/*.wav,data/images/original/*
#
#    This can be translated into:
#
#[app:source.exclude_patterns]
#license
#data/audio/*.wav
#data/images/original/*
#


#    -----------------------------------------------------------------------------
#    Profiles
#
#    You can extend section / key with a profile
#    For example, you want to deploy a demo version of your application without
#    HD content. You could first change the title to add "(demo)" in the name
#    and extend the excluded directories to remove the HD content.
#
#[app@demo]
#title = My Application (demo)
#
#[app:source.exclude_patterns@demo]
#images/hd/*
#
#    Then, invoke the command line with the "demo" profile:
#
#buildozer --profile demo android debug

I get exactly the same error on Ubuntu 18.04 with latest buildozer cloned from GitHub.

Is JAXB in use? I get this error too. I don't know much about Java but I did find this:
https://www.jesperdj.com/2018/09/30/jaxb-on-java-9-10-11-and-beyond/

[inclement]

I think Android still doesn't support Java versions higher than 8. There's not much we can do about that, the solution is to use Java 8. We could have a clearer error message though.

[EternityForest]

Interesting. I wasn't aware that the JDK on the dev machine had anything to do with the VM on the device itself. If that's the case a bit of documentation would be great for any future travelers here. Using Java 8 is fairly trivial once you know that's actually the correct thing to do and not just a hack.

It's not about JDK having anything to do with the VM, it's because their toolchain uses JDK in some places and is not compatible with JDK 12.

[zurgeg]

It still has the same error after installing JDK8

[AndreMiras]

Buildozer (master branch) now also supports more recent JDK versions #1135
