Manifest of org.glassfish.hk2/hk2 generates false warnings #462
Comments
Furthermore the error is strange:
It should not be Maybe there's something wrong in the MANIFEST? |
Indeed the problem is in the MANIFEST. You use Anyway, the error displayed is not blocking, since the required packages are anyway downloaded (I don't know how...). Example from https://mvnrepository.com/artifact/com.fasterxml.jackson.module/jackson-module-jaxb-annotations/2.9.9

Looking at the pom, I don't see anything wrong with the dependencies at first glance: http://repo1.maven.org/maven2/org/glassfish/hk2/hk2/2.5.0-b42/hk2-2.5.0-b42.pom The entries in the generated class-path are correct, they don't have the version because that's how it's stated in the maven-jar-plugin configuration of the pom:
Note that this artifact does not contain any code, it's more like a meta-module or meta-bundle that exposes HK2 as a module, it should probably not be included in your app.

For info, I ran into this too; specifically I was getting this on starting the application: The Class-Path manifest attribute in /Users/joseph/.m2/repository/org/glassfish/hk2/hk2/2.5.0-b42/hk2-2.5.0-b42.jar referenced one or more files that do not exist: file:/Users/joseph/.m2/repository/org/glassfish/hk2/hk2/2.5.0-b42/hk2-utils.jar,file:/Users/joseph/.m2/repository/org/glassfish/hk2/hk2/2.5.0-b42/javax.annotation-api.jar,file:/Users/joseph/.m2/repository/org/glassfish/hk2/hk2/2.5.0-b42/javax.inject.jar,file:/Users/joseph/.m2/repository/org/glassfish/hk2/hk2/2.5.0-b42/hk2-api.jar in this project: https://gitlab.com/openid/conformance-suite I discovered that upgrading to SpringBoot 2.2.0 (previously using 2.1.5) seems to stop the warning appearing. |
This avoids an annoying warning (and some unhelpful exceptions thrown & caught) on starting the app: eclipse-ee4j/glassfish-hk2#462 but probably also pulls in some security & other fixes, and generally staying up to date seems like a good plan if it doesn't break anything.

Sadly I was mistaken; upgrading to springboot 2.2.0 just made the error appear in a subtly different form/place; I still get:
This is from building+running https://gitlab.com/openid/conformance-suite in IntellIiJ - dependency tree here: https://gist.github.com/jogu/5c51b8368c45c04af43eecd6fe3d74f0 Project is packaged as a jar. @romain-grecourt I think that answers all your questions; please let me know if there's any further questions. |
i think its something to do with spring boot devtools, I am getting:
My dependencies are just the default:

EDIT: see comment number 3
I'm using a Spring Boot 2 application that needs
hk2
version 2.5.0-b42 as dependency. Gradle 5.4.1 downloadshk2.jar
without problems, but not its dependencies. This happens only withhk2
. It does not work also with version 2.5.0.I checked on internet and there's people that have this problem with this library with maven too. One example:

EDIT: I also tried to explicitly set the dependencies, and also to change from Maven Central to JCenter, but nothing. I think for the moment I have to download them manually.
