What version did you use? I've tested this and it worked fine for me... maybe there is some missing dependency in distribution package?

wojciech.kapcia@tigase.net commented 5 months ago

Latest nightly docker image

Andrzej Wójcik (Tigase) commented 5 months ago

I think I found the cause of the issue. Locally, for testing, I've used distribution package but with locally installed Java (that is JDK). In our container image we are installing JRE (not JDK) and due to that gg.jte is unable to find JavaCompiler using javax.tools.ToolProvider.

Just for reference - https://stackoverflow.com/questions/15513330/toolprovider-getsystemjavacompiler-returns-null-usable-with-only-jre-install

We have 2 solutions here:

Use JDK in our image - simple to apply and rather easy to do, but I would prefer to not include full JDK if possible.
Precompile JTE templates to Java classes during maven build - there is a maven plugin for that, and I think this would be good to distribution builds (not for development though)

I'll work on fixing the issue with precompiled JTE templates.

This should fix the issue. Waiting for container image rebuild to verify the fix.
