Intellij 多模块项目 - 找不到符号

Question

I am working on a project which has multiple modules like client, common, server. In the server module of the project I have a service which is referencing to a new class I created in the common module. For some reason, when I run the project locally, I repeatedly get this error ->

Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin ....   cannot find symbol 
[ERROR] symbol : class Document

for the new Document class I added in the common module.

When I Build -> Rebuild my common module and server module again, the error goes away. But when this happens, it fails during runtime with ClassNotFoundException I am running project with mvn spring-boot:run command

Is there a permanent fix for this?

I think I need to fix the structure of project or add the right dependency in the settings.

Answer 1

I ran mvn install for the common module and it fixed all problems. Thanks.
