Arch Linux User Repository

Christian Foltin (the author of software) adapted code to compile and run with java17, but for version 1.1.0 only. Stable version (1.0.1) perfectly runs with jre11-openjdk. Java SE 11 is LTS release, so I believe it's OK. To run freemind with non-default java version one can use simple command: env JAVA_HOME=/usr/lib/jvm/java-11-openjdk freemind

@dreieck Thank you for your suggestions. I will create -bin package with suggested changes and request merging.

@sinbud2004 I still think that env JAVA_HOME=... freemind is better approach. No need to sudo, no system-wide changes (other programs are unaffected).

@butla The same problem and the same solution. Use java-11, not java-17. I think, I will change the package to use Java 11 explicitly.

This package should be renamed to freemind-bin since you do not build from Java sources.

With renaming, also provides=("freemind=${pkgver}"), conflicts=("freemind"), `replaces=("freemind<=1.0.1") should be added.

Regards and thanks for maintaining!

I have tested many situations. For example, Dbeaver requires >java-17-openjdk to run, but freemind requires java-11-openjdk to run. I have installed both sudo pacman -S jre11-openjdk jre17-openjdk . I just need to write a switch for one of them.

freemind.sh

#!/usr/bin/bash
sudo archlinux-java set java-11-openjdk
freemind %U
sudo archlinux-java set java-17-openjdk

In this way, when you run freemind, you will switch to the environment it needs. It should be noted (1) Freemind and Dbeaver cannot run at the same time. (2) Sudoer needs to be set to user without password.

I was getting an error like this on Manjaro:

Anyways, I've noticed that Freemind has a successor fork - Freeplane - which is available in the community repos, so I switched to that.

It also needed a tweak to pick a Java runtime different from the latest, though:

sudo pacman -Sy jre17-openjdk
sudo archlinux-java set java-17-openjdk

@theRedCyclops Thank you for letting me know. This is an issue of the precompiled freemind package. Sadly it hasn't been maintained for the last 8 or so years. For now, I advise to use a JRE with version 8. That is the LTS version of java and will definitely work with freemind. I'll try to make my own freemind binaries that are compatible with newer versions of java, but that will take some time to properly do. So please stay patient. :)

this package is currently broken on the latest java release
