"Error: Could not find or load main class" in a Module of Spring Boot

3661 views java

I have a Spring Boot app that is in a Module within a project.

The module has its own pom.xml and the outer project has its own pom.xml

The module's pom.xml has the <mainClass>...</mainClass> annotation pointing to the main class of the app.

It also has a reference to the parent pom.xml with the <parent>...</parent> property, pointing to the parent artifactId, groupId & version.

When running the app within Intellij, it runs OK.

The problem is when trying to run the app from the jar:

 java -jar myApp.jar

Then we get and error of

Error: Could not find or load main class com.example.application

What are we missing here?

answered question

Can you provide your pom.xml?

Open your jar file with winzip or winrar, if you are using linux use archive manager. Then go to the META-INF, open the MANIFEST.MF and make sure that the property "Main-Class: your.class.path" is correct.
