Unable to import spring boot jar file in another POM spring boot application-CodePudding

I have 2 spring-boot applications. 1. search-engine, 2. post-engine. I am trying to include the search-engine jar into the post-engine POM file.

Here is my search-engine POM file.

Here is my post-engine POM file.

After I mvn clean install the search-engine project, I am doing mvn clean install of post-engine which includes search-engine jar. The build is also successful. The issue is that if I try to use any service or any classes from the search-engine service inside the post-engine service, it cannot import it.

What configuration am I missing?

See the image for errors.

CodePudding user response：

try to manage your two projects like modules. Create a root project that will contain the two projects and declare in the parent pom your current projects like modules.

E.g. https://spring.io/guides/gs/multi-module/

CodePudding user response：

Anyway, I created a base project and included these 2 projects in its POM.

Gave the packaging as POM <packaging>pom</packaging>.

   <modules>
    <module>../search-engine</module>
    <module>../post-engine</module>
</modules>
<dependencies>
    <!--  Search-Engine module dependency  -->

        <version>0.0.1-SNAPSHOT</version>
    </dependency>

    <!--  Post-Engine module dependency  -->
