i made a spring boot webflux hello world, lein run works fine, but when i do lein uberjar and the java -jar my-standalone.jar doesn't work

Takis_15:04:09

can leiningen make uberjars for spring-boot? i should do something extra to make it work?

Takis_15:04:53

java -jar demo-lein-0.1.0-SNAPSHOT-standalone.jar

and then terminates, looks like Netty doesn't start at all

this is ok, server listens on 8080

seancorfield16:04:08

Oh, except that's empty...

seancorfield16:04:41

@U68Q5G1BJ Maybe you didn't push the code, or the repo is private?

Takis_16:04:09

no i am sorry https://github.com/tkaryadis/demo-lein , i forgot to make it public

Takis_16:04:13

now its ok, i will be back in 30 min i have to do something, thank you for trying to help me, first time i tried uberjar with spring-webflux

seancorfield17:04:29

I had a look and I don't know why it works with lein run but fails to start Netty when bundled as a JAR...

Takis_17:04:46

thank you for trying to help me. maybe someone will know, also i wonder leiningen and spring can be used? or i have to use something like clojurephant and gradle? i use webflux and HTMX development with lein it was very easy, only the uberjar problem
