@Tio, a clean install of the jre11-openjdk package -which already is a dependency of my package- should set everything up for you. It installs the JRE in /usr/lib/jvm/java-11-openjdk/. Additionally, you may want to set the value of the environment variable$JAVA_HOME (in your ~/.bash_profile or ~/.bashrc, or simply in your terminal, but this is not permanent) like this:

export JAVA_HOME=/usr/lib/jvm/java-11-openjdk/

but this is not strictly necessary, as the jre11-openjdk already adds the binaries to the $PATH.

Ok. I do not know how to do these...but thank you for the answer.

Tio, you either need the $JAVA_HOME variable pointing to your Java 11 installation, or the java executable in your $PATH.

Hi. I already have jre11. I removed jre8 so that perhaps it will use jre11. However now I get this error:

[tio@tio-pc ~]$ gaiasky
/usr/bin/gaiasky: line 80: java: command not found

@Tio you are using the jre 8 to run it, but should be using at least jre 11 (which is a dependency). Check your java installations and make sure you have the right version. You can check the gaiasky script itself to see how the jre is chosen. Maybe you have Java 8 in your $JAVA_HOME or $JRE_HOME vars.

Wanted to say I get this error:

gaiasky

No, sorry everything is ok. I just thought the older/newer mismatch is because of the "typo" in pkgver as it is not like the source version. But apparently this is on purpose.

@gosi, I'm a bit confused now, I changed the hyphen to an underscore following the guidelines here: https://wiki.archlinux.org/index.php/PKGBUILD#Version

What is then the right way to go?

gaiasky: local (2.2.4.276701f80-1) is newer than AUR (2.2.4_1.a169540c8-1)

5 days Fix previous release 2.2.4-1

Almost: pkgver=2.2.4_1.a169540c8

that should be: pkgver=2.2.4-1.a169540c8

@pancakes, just updated it. The script that generates the AUR package crashed and I didn't care to check the logs. Thanks!
