Currently, I am able to use sdkman and install java for the wrong architecture on a raspberry pi. It looks like it isn't doing some detection for the raspberry pi to prevent the install and is downloading an x86 64 bit version of java.

See error below:

pi@raspberrypi:~ $ sdk install java

Downloading: java 8.0.163-zulu

Do you want java 8.0.163-zulu to be set as default? (Y/n): Y

I think the main problem here is that we are currently interpreting the output of uname incorrectly. Would you be able to share the output of uname on your pi please? We also don't have any Java versions available for ARM right now, but let's solve that after this is resolved.

@marc0der I intended to do that last night, I'll make sure to get that output for you when I get home this evening.

For uname -a: Linux raspberrypi 4.14.34-v7+ #1110 SMP Mon Apr 16 15:18:51 BST 2018 armv7l GNU/Linux

For uname it just shows Linux

Bump for armv6 for Raspberry Pi Zero W.

pi@raspberrypi:~ $ uname -a
Linux raspberrypi 4.14.71+ #1145 Fri Sep 21 15:06:38 BST 2018 armv6l GNU/Linux

@marc0der, would a pr help get this done sooner? If so I'd be happy to assist.

[marc0der]

Since we don't support the arm architecture, this will have wide reaching effects in in the sdkman-hooks project as well as in db migrations. But sure, feel free to raise PRs.

Can't this issue be closed because of PR #769 ?
