Arch Linux User Repository

grandchild: Does compilation work now? If not: can you build Mindustry from source using the instructions on its homepage?

Hey there, I'm getting an error during build, about some Android SDK license not being accepted. I do have Android Studio installed, maybe it's detecting something?

$ archlinux-java get
java-11-openjdk

I'm curious why it would try and build the android app anyway...

Here's the error (with some usual generic Gradle error stuff removed):

@Daniel071 If you find a way to programmatically download releases from itch.io - please tell me, I don't know how to do this. The link is updated and has an expiration date and a unique token. Also, releases from itch.io don't contain the source code, so you submitted an out-of-date request to a wrong package (more appropriate would be mindustry-bin or mindustry-server-bin). GitHub repository doesn't contain tags for v104.5, so I can't build it from source either in this package. If you want the latest version - try mindustry-git.

@vasya @Corubba I can't replicate the error you get, although I added some code to find and select a compatible JDK nevertheless. Sorry for a late response, it's holidays after all.

Generally it's a mess I think, no really good solution. Something that would "mostly" work is:

export PATH="/usr/lib/jvm/java-8-openjdk/jre/bin/:$PATH"
export PATH="/usr/lib/jvm/java-9-openjdk/jre/bin/:$PATH"
export PATH="/usr/lib/jvm/java-10-openjdk/jre/bin/:$PATH"
export PATH="/usr/lib/jvm/java-11-openjdk/jre/bin/:$PATH"
export PATH="/usr/lib/jvm/java-12-openjdk/jre/bin/:$PATH"
./gradlew ...args...

the app itself is runnable on jre-13, just checked.

Unfortunately I do not know any way to even pin specific version, like 8, without also specifying that it should be openjdk specifically.

vasya, could you please provide an example script which selects JRE on Arch based on its version?

... and mindustry dev said that gradle 6 won't be supported for now, so we need to fix it in AUR.

One way of doing that is to specify the dependencies like that: depends=("java-runtime>=8" "java-runtime<13")

This will ensure that the right jre is installed, but it won't check on what's actually used. To make the *.sh script work properly, the PATH tricks (mentioned in prev comments) need to be used....

I've raised an issue upstream, hopefully they'll fix it soon. https://github.com/Anuken/Mindustry/issues/1291

In case someone else hits a Unsupported class file major version 57 during the gradle build: Gradle supports Java13 only from version 6 onwards. You need to change the url in gradle/wrapper/gradle-wrapper.properties to the latest v6 release (6.0.1 at time of writing).

Builds fine. Thanks for changing! Run-time was already using system-s default, 11 in my case, so there's no explicit reason to check. (And I'm at work now.)
