Spring Boot Maven Plugin – Exclude a dependency

By default, both the repackage and the run goals will include any provided dependencies that are defined in the project. A Spring Boot project should consider provided dependencies as container dependencies that are required to run the application.

Some of these dependencies may not be required at all and should be excluded from the executable jar. For consistency, they should not be present either when running the application.

There are two ways one can exclude a dependency from being packaged/used at runtime

Exclude a specific artifact identified by groupId and artifactId (optionally with a classifier if needed)
Exclude any artifact belonging to a given groupId

The following excludes com.foo:bar (and only that artifact)

<project>
  ...
  <build>
    ...
    <plugins>
      ...
      <plugin>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-maven-plugin</artifactId>
        <version>2.0.3.RELEASE</version>
        <configuration>
          <excludes>
            <exclude>
              <groupId>com.foo</groupId>
              <artifactId>bar</artifactId>
            </exclude>
          </excludes>
        </configuration>
        ...
      </plugin>
      ...
    </plugins>
    ...
  </build>
  ...
</project>

This example excludes any artifact belonging to the com.foo group

<project>
  ...
  <build>
    ...
    <plugins>
      ...
      <plugin>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-maven-plugin</artifactId>
        <version>2.0.3.RELEASE</version>
        <configuration>
          <excludeGroupIds>com.foo</excludeGroupIds>
        </configuration>
        ...
      </plugin>
      ...
    </plugins>
    ...
  </build>
  ...
</project>
