在运行spring boot jar时使用外部jar作为依赖文件

Question

I have a Maven-Springboot project setup. After doing a mvn install I can run the jar file in command prompt using java -jar <my-jar-file.jar>

There was a dependency to a jar say as-common-1.0.0.jar that is there in my-jar-file.jar . Now I want to override the version of this dependent jar at run time by giving an external jar. something like:

java -jar my-jar-file.jar using as-common-1.0.1.jar

I went through many SO posts like this include external jar when running java -jar but they didn't help.

is it achievable?

EDIT: The issue we have is many of our applications depend upon one of our internal framework jar which gets updated(version) often. So every time changing the pom file and re-deploying all the apps doesn't look feasible to us. We want somehow the dependency of this particular jar is given at run time. Any idea regarding best possible way to manage this scenario ?

Answer 1

No, this is not sensible. At best, you would load classes twice and this may/may not work.

If you build a complete jar containing everything, you cannot swap content at runtime. You need to rebuild it.
