I wanted to run maven-assembly-plugin and create a jar file with all dependencies added to it. When I run java -jar jarfile.jar, I get the below error:
no main manifest attribute, in target/jarfile.jar
I went through several Stack Overflow posts for the same and tried all permutations and combinations. I tried adding both assembly and shade plugins. You can see the settings I have in my pom.xml above. I'm not really sure on how this is happening even though I added proper maven settings.
I verified that Java is running fine:
I verified whether I specified the main class correctly.
Everything looks fine for me except the results and I'm confused at the moment.
What might be going wrong? I expect some of them still mark the question as "duplicate", but I have been reading other posts and tried changing the settings accordingly. None of them worked.
