Exclude embedded server based on maven profile

Question

I have two different profiles (dev and prod) defined in my pom.xml. I don't want to include an embedded server while building a project with a prod profile. I know even if I don't exclude embedded server from the jar, I can deploy it on other servers.

I have checked how two exclude tomcat using below snippet:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
    <exclusions>
        <exclusion>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-tomcat</artifactId>
        </exclusion>
    </exclusions>
</dependency>

I'm not able to figure out how to exclude it on the basis of the selected profile. Below are the build and profile properties of my POM.xml. Please guide.

<build>
        <resources>
            <resource>
                <directory>src/main/resources</directory>
                <filtering>true</filtering>
                <includes>
                    <include>application.properties</include>
                    <include>application-${profileName}.properties</include>
                    <include>*.xml</include>
                </includes>
            </resource>
        </resources>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
</build>
<profiles>
        <profile>
            <id>dev</id>
            <activation>
                <activeByDefault>true</activeByDefault>
            </activation>
            <properties>
                <profileName>dev</profileName>
            </properties>
        </profile>
        <profile>
            <id>prod</id>
            <properties>
                <profileName>prod</profileName>
            </properties>
        </profile>
</profiles>

Thanks in advance.

Answer 1

Try to use dependencies tag into your profile , include only the dependencies that you want for that profile.

<profiles>
    <profile>
        <id>dev</id>
        <dependencies>
            // do stuff
        </dependencies>
    </profile>
</profiles>

Answer 2

Try something like that:

    <!-- Other profiles -->

    <profile>
        <id>prod</id>
        <dependencies>
            <dependency>
              <groupId>org.springframework.boot</groupId>
              <artifactId>spring-boot-starter-tomcat</artifactId>
              <scope>provided</scope>
            </dependency>
        </dependencies>
    </profile>

    <!-- Other profiles -->

</profiles>

However, you have to be careful to the application packaging. Maybe you need to switch the fat jar (used for the development environment) to a war for your production environment (Since you will exclude the embedded server).
