Artifact of Spring Boot project generated by IntelliJ IDEA causes errors

Question

I am working on a Spring Boot project using IntelliJ IDEA and everything works fine. I have no problem running and testing the application inside IntelliJ IDEA. It runs perfectly whether I configure it as an "Application" or "Spring Boot" (from the Run/Edit Configuration menu)

However, problems occur after I created an artifact and try to run it using "java -jar AppName.jar". It spews out errors like:

Could not find key 'spring.profiles.active' in any property source

and

Caused by: java.lang.IllegalArgumentException: No auto configuration classes found in META-INF/spring.factories. If you are using a custom packaging, make sure that file is correct.

I extracted the jar file and the spring.factories, etc. files are indeed inside the folder "META-INF".

I suspect the cause of the problem is the class path. When I run it from within IntelliJ IDEA, I noticed that it is set to module in "Use Classpath of Module". However, in the artifact, I could not get the settings right.

What do you think is the cause of the problem? I think it is the class path. If not, what else can it be? Please help!

I'm providing my pom.xml file here:

I have search and tried other examples/solutions and none worked.

Please help! Thanks!

Answer 1

If it is an maven project, it is recommended to add pom.xml

<packaging>war</packaging>

Answer 2

Problem is resolved.

In the IntelliJ Artifacts Create JAR from Modules dialog box, I have to

1. choose "Copy to output directory and link via manifest" option
2. make sure the META-INF/MANIFEST.INF file is set to "src/main/resources"

Everything is working now (after spending the entire afternoon).
