Maven build problem with Spring Boot 2.7.0 and 2 jars per module
I'm migrating from Spring Boot 2.0.4 to 2.7.0 and facing the following problem:
Project structure
Multi-module project:
/parent-project
+core
+monitoring
+simulator
Project "monitoring" depends on "core".
Project "simulator" depends on both "monitoring" and "core".

Problem
In Spring Boot 2.0.4, when I compile the project "monitoring", it will build 2 jar files as below:
The file "monitoring-flat.jar" is full-packed and used for standalone execution via java -jar command.
The file "monitoring.jar" is not full-packed, which is used for compiling the dependence project "simulator".
This works fine in Spring Boot 2.0.4.
However, when I migrated to Spring Boot 2.7.0, it will not work anymore. The output will be as follow:
Both file "monitoring-flat.jar" and "monitoring.jar" is full-packed. In addition, I see that the file "monitoring.jar.original" is not full-packed.
When compiling the project "simulator", an error will happen because it cannot access the compiled class from the file "monitoring.jar".

From your log it is seen that repackage is executed twice:
[INFO] --- spring-boot-maven-plugin:2.7.0:repackage (repackage) @ monitoring ---
[INFO] Replacing main artifact with repackaged archive
[INFO]
[INFO] --- spring-boot-maven-plugin:2.7.0:repackage (default) @ monitoring ---
[INFO] Attaching repackaged archive ...\src\monitoring\target\monitoring-flat.jar with classifier flat
So for the second time, it will do harm
See https://docs.spring.io/spring-boot/docs/2.7.x/maven-plugin/reference/htmlsingle/#packaging
If you are using spring-boot-starter-parent, such execution is already pre-configured with a repackage execution ID so that only the plugin definition should be added.
That is if you are using Spring parent, that adding plugin like this is enough (and so is written in the doc start, and so is produced by https://start.spring.io/ new Spring project)
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
The spring-boot-starter-parent POM includes configuration to bind the repackage goal.
P.S.
And actually you don't need any extra configuration for spring-boot-maven-plugin, you just rename
monitoring.jar -> monitoring-fat.jar
monitoring.jar.original -> monitoring.jar
Note that industry name is fat .jar, not flat .jar, see What is a fat JAR?
So may be better rename like
monitoring.jar.original -> monitoring-skinny.jar

Add Following to monitor
<properties>
<spring-boot.repackage.skip>true</spring-boot.repackage.skip>
</properties>

I found the solution based on following reference:
https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-2.1-Release-Notes
https://docs.spring.io/spring-boot/docs/2.1.4.RELEASE/maven-plugin/examples/repackage-classifier.html
Maven Plugin
The finalName property is no longer customizable to align with the behavior of standard Maven plugins.If you were customizing the repackage goal, the main execution has now an id of repackage that must be specified, see the updated sample.
It is simple, just add the <id>repackage</id> to the file src/monitoring/pom.xml, then it will work
