Local jar file didn't works about obsidian-plantuml

[BaumiCoder]

I had some other issues with obsidian lately. Now I find a reason for this.

reason for problems (flatpak)

I was using the flatpak installation of obsidian. Flatpak applications are running in a kind of an sandbox. So a java -jar plantuml.jar on the shell works fine (with OpenJDK 18), but the obsidian in the flatpak sandbox doesn't works (maybe there couldn't be found any java in the sandbox).

solution for problems

Now I installed obisidian as deb-package an with that all works fine.

ToDo for plugin

In my opinion the only ToDo for the plugin would be to show a error message, what went wrong while using jar file.

So I'm not sure about version 11 but I had issues using Java version 17, you can see the errors if you invoke the jar directly.

$ java -jar plantuml.jar 
Exception in thread "main" java.lang.UnsatisfiedLinkError: Can't load library: /usr/lib/jvm/java-17-openjdk-17.0.5.0.8-2.fc36.x86_64/lib/libawt_xawt.so

So I installed Java 8 and I am now able to launch the jar directly however I still get the "Generating PlantUML diagram" message, I agree a better error message would be nice.

Same here, found bug when using flatpak version of obsidian.
Tried setting java path to /var/run/host/{my_java_executable_path} fixed issue (see flatpak docs)

@joethei i think, that info should be added to Known Issues section.
