Spring Boot with multiple entry points applications via Maven profiles

Question

I'm trying to prototype a structure in which several @SpringBootApplications are segregated by means of their packaging namespaces, like so:

In Maven pom.xml, to build, I'm relying on profiles, as shown below, and described here and here:

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <executions>
                    <execution>
                        <goals>
                            <goal>repackage</goal>
                        </goals>
                        <configuration>
                            <mainClass>
                                ${spring.boot.mainclass}
                            </mainClass>
                        </configuration>
                    </execution>
                </executions>
            </plugin>
            <plugin>
                <artifactId>maven-surefire-plugin</artifactId>
                <version>3.0.0-M6</version>
            </plugin>
        </plugins>
    </build>

    <profiles>
        <profile>
            <id>dcr</id>
            <properties>
                <spring.boot.mainclass>com.pru.globalpayments.feeds.downstream.dailycashreport.DcrDataFactoryApplication</spring.boot.mainclass>
            </properties>
        </profile>
        <profile>
            <id>other</id>
            <properties>
                <spring.boot.mainclass>com.pru.globalpayments.feeds.downstream.anothersystem.AnotherSystemDataFactoryApplication</spring.boot.mainclass>
            </properties>
        </profile>
    </profiles>

</project>

My attempts to build the codebase (per spring-boot-maven-plugin spec) result in the following:

>mvn clear package -Drun.profiles=dcr

[ERROR]

Though the above reference suggests invocation via -Drun.profiles=dcr, the regular Maven way, via -P dcr was also tried, unsuccessfully. It returns the same error message.

What am I missing?

The above approach is also referred to here - is that answer incrorrect?

Thank you in advance.

Some further experiments lead me to believe that the culprit is somewhere within the spring-boot-maven-pluginconfiguration/invocation as even when I disable profiles stanza in pom.xml completely, the error message remains the same, it doesn't distinguish between the 2 profiles and doesn't substitute the ${spring.boot.mainclass} property:

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <executions>
                    <execution>
                        <goals>
                            <goal>repackage</goal>
                        </goals>
                        <configuration>
                            <mainClass>
                                ${spring.boot.mainclass}
                            </mainClass>
                        </configuration>
                    </execution>
                </executions>

                <version>3.0.0-M6</version>
            </plugin>
        </plugins>
    </build>
<!-- 
    <profiles>
        <profile>
            <id>dcr</id>
            <properties>
                <spring.boot.mainclass>com.pru.globalpayments.feeds.downstream.dailycashreport.DcrDataFactoryApplication</spring.boot.mainclass>

            </properties>
        </profile>
    </profiles>
-->
</project>

The same error persists when plugins are configured slightly differently, without using profiles:

<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <executions>
                <execution>
                    <id>repackage-dcr</id>
                    <phase>package</phase>
                    <goals>
                        <goal>repackage</goal>
                    </goals>
                    <configuration>
                        <mainClass>com.pru.globalpayments.feeds.downstream.dailycashreport.DcrDataFactoryApplication</mainClass>
                        <finalName>dcr</finalName>
                        <outputDirectory>target/apps</outputDirectory>
                    </configuration>
                </execution>
                <execution>
                    <id>repackage-other</id>
                    <phase>package</phase>
                    <goals>
                        <goal>repackage</goal>
                    </goals>
                    <configuration>
                        <mainClass>com.pru.globalpayments.feeds.downstream.anothersystem.AnotherSystemDataFactoryApplication</mainClass>
                        <finalName>other</finalName>
                        <outputDirectory>target/apps</outputDirectory>
                    </configuration>
                </execution>
            </executions>
        </plugin>
        <plugin>
            <artifactId>maven-surefire-plugin</artifactId>
            <version>3.0.0-M6</version>
        </plugin>
    </plugins>
</build>

and invoked with simple mvn clean package.

Reading more carefully into the Spring Boot Maven plugin documentation, looks like it's not intended to recognize Maven profiles at all, making the foundation on which this experiment is based, referred to above so much shakier:

`run.profiles` is not how you select a maven profile. You want `-P dcr` — tgdavies, Aug 01 '23 at 00:50
You can try following this: https://www.baeldung.com/spring-boot-main-class — tgdavies, Aug 01 '23 at 01:07
I tried that article, as I tend to do my own research prior to posting, but that approach doesn't provide the ability to have several @SpringApplications configured in a single codebase. Here's my related question on that topic: https://stackoverflow.com/q/76806971/283837 — Simeon Leyzerzon, Aug 01 '23 at 01:12
Are you trying to have a single executable jar containing several applications? — tgdavies, Aug 01 '23 at 01:14
As is noted in my question and, according to the answers referred to, should be possible. — Simeon Leyzerzon, Aug 01 '23 at 01:17
Anything you do via maven profiles is build time, not run time. The approach you are asking about in this question is not going to give you several applications in a single executable jar. — tgdavies, Aug 01 '23 at 03:00
Can you share please any *Application.java content to verify `@Profile` is set correctly? — Valijon, Aug 01 '23 at 12:23
@Valijon I only tried using Maven profiles, no Spring ones at this point. You could find a source for the `*Application.java` in another ticket I posted: https://stackoverflow.com/q/76806971/283837 — Simeon Leyzerzon, Aug 01 '23 at 12:24

Seems mainClass configuration is not placed in the right place:

<plugin>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-maven-plugin</artifactId>
    <configuration>
        <mainClass>${spring.boot.mainclass}</mainClass>
    </configuration>
    <executions>
        <execution>
            <goals>
                <goal>repackage</goal>
            </goals>                        
        </execution>
    </executions>
</plugin>

@SimeonLeyzerzon I've tested with `spring-boot-maven-plugin:3.1.2`. Let me see previous versions — Valijon, Aug 01 '23 at 13:49
@SimeonLeyzerzon with `spring-boot-maven-plugin:2.7.13` works fine! — Valijon, Aug 01 '23 at 13:59
My version is 2.7.13 as is clear from the error message. In any case, looks like this plugin doesn't recognize Maven profiles, see my updates. — Simeon Leyzerzon, Aug 01 '23 at 13:59
@SimeonLeyzerzon please, update your question and share your current `spring-boot-maven-plugin` setup — Valijon, Aug 01 '23 at 14:02
Do you have some codebase you could link to to see what works fine for you? — Simeon Leyzerzon, Aug 01 '23 at 14:03

I cannot use chat - it is blocked for me here. What do you mean by `spring-boot-maven-plugin` setup? I could post the whole `pom.xml` if that helps — Simeon Leyzerzon, Aug 01 '23 at 14:05
@SimeonLeyzerzon try please https://github.com/Valijon/downstream-data-factory — Valijon, Aug 01 '23 at 14:28
@SimeonLeyzerzon also try to remove `spring-boot-maven-plugin` files and run `mvn clean package -P dcr` to download them again: `C:\Users\YOUR_USER\.m2\repository\org\springframework\boot\spring-boot-maven-plugin\2.7.13` — Valijon, Aug 01 '23 at 14:33
Thanks, will try running that minimal version in a separate repo shortly. Also, seeing a bit of a discrepancy where the fully classified name of the `AnotherSystemDataFactoryApplication` is `com.pru.globalpayments.feeds.downstream.anothersystem.AnotherSystemDataFactoryApplication.AnotherSystemDataFactoryApplication` according to your package definition but supposedly gets picked by `com.pru.globalpayments.feeds.downstream.anothersystem.AnotherSystemDataFactoryApplication` in the pom.xml. You ran it via `mvn clean package -P other`? — Simeon Leyzerzon, Aug 01 '23 at 14:44
@SimeonLeyzerzon yes, i will share all `mvn clean package -P other` traces — Valijon, Aug 01 '23 at 14:49
