Error Deploying to Heroku - no main manifest attribute, in build/libs/uat-1.0.0-SNAPSHOT.jar
chavu opened this issue · comments
I deployed successfully to Heroku yesterday. Today I deployed an update to my app and the app doesn't run. The log shows:
2023-11-21T23:16:55.149590+00:00 heroku[web.1]: Starting process with command `java -jar build/libs/uat-1.0.0-SNAPSHOT.jar`

2023-11-21T23:16:55.815617+00:00 heroku[web.1]: State changed from starting to crashed
Then I added the following to gradle following advise I found on google.
project.tasks.withType<Jar> {
manifest {
attributes["Main-Class"] = mainClassName
}
}
It's now showing the following error:

It seems Ktor fullstack project packaging is broken in KVision 7.1.0. As a spring boot user I haven't noticed that. Sorry about this. I'll try to release a fix asap.
Thank you. I have downgraded to 7.0.1 for now and it's working okay.
Fixed in 7.2.0
I upgraded to version 7.2.0 and when I run the app in development on my laptop I 'm getting a blank white screen. See console erros in image below.
Any errors in the Network tab? Is your backend running? What task do you use to run the backend?
Suprising after downgrading and then upgrading again and rebuild, It's working fine now. Sorry.
