Maven强制依赖项使用较低版本的Spring Boot

Question

My Spring Boot application's spring boot parent version is 1.5. There is a custom dependency whose spring boot version is 2.0. I want to force this dependency to use spring boot 1.5 in main Spring Boot application.
Given that: Dependency's version cannot be downgraded as it is being used by other apps and cannot upgrade the spring boot main app to 2.0 from 1.5. Dependency works well for both SB 1.5 and 2.0 well. Exclusion tags were also added to exclude springboot 1.5. but it was also not successful.

Please let me know how to force the dependency to use 1.5 at run time ?

Answer 1

You cannot change the parent POM of a dependency.

You can, though, overwrite dependencies that are defined in a dependency's parent POM. This can be done using the same mechanisms as overwriting other transitive dependencies ( <dependencyManagement> ).

As dependencies are the only way a parent POM of a dependency contributes to your build, you have no need to change it.

Answer 2

You can enforce consistent dependencies in whole project with rule Dependency Convergence.

<plugin>
     <groupId>org.apache.maven.plugins</groupId>
     <artifactId>maven-enforcer-plugin</artifactId>
     <version>1.3.1</version>
     <executions>
        <execution>
           <id>enforce</id>
           <configuration>
              <rules>
                 <DependencyConvergence/>
              </rules>
           </configuration>
           <goals>
              <goal>enforce</goal>
           </goals>
        </execution>
     </executions>
  </plugin>
