Consider reducing fatjar by excluding ide-deps

[ennishol]

I ran fatjar export and found:

du -sh META-INF/*

57M     META-INF/ide-deps

1.6M    META-INF/maven

236K    META-INF/template-html-builder.css
4.0K    META-INF/thirdparty-LICENSE
272K    META-INF/versions

57m of ide-deps. Can it be excluded/removed from the resulting fatjar?

Thanks you!

which jar is that? What did you export?

@maxandersen Steps to reproduce:

• jbang init -t qcli quarkusCli.java
• ./quarkusCli.java
• jbang export fatjar quarkusCli.java
• unzip quarkusCli-fatjar.jar
• du -sh META-INF/*

ah this is more quarkus integration specific - afaics jbang doesn't put these in the build result.

its https://github.com/quarkusio/quarkus/blob/main/core/launcher/src/main/java/io/quarkus/launcher/JBangIntegration.java that affects what ends up in the .jar file after jbang compiled core code.

but yes, those deps seems to be unnecessarily added - or at least shouldn't need to be add unless you run in quarkus devmode (-Dquarkus.dev) but even then I'm surprised they even end up there.

Want to take a crack at fixing or figuring it out?

in any case best if you open issue on quarkusio and link to this as I'm 98% sure its pure quarkus fix - but might need some hooks on jbang side to make most efficient.

But I'm actually quite surprised to see those ide-deps in the fat jar, because they don't exist in the quarkusCli jar itself, nor do they appear in the quarkus-core jar. So where are they coming from?

Edit: ok, they come from the quarkus-ide-launcher dependency.

[maxandersen]

Yeah - and i think that dependency is added "too eagerly" by the Quarkus integration.
