It may cause version mismatch issue in runtime. This is a case where the application author ie, you needs to step in and ensure that all of the dependencies play nicely. But sometimes bugfixes make that impossible. If they are not present there, then Maven will download them from a remote repository and store them in the local repository.

Maven dependency exclude


The systemPath element refer to the location of the JAR file. Maven has a somewhat bogus approach to resolving those conflicts, in that the version closest to the root of the tree wins. Transitivity brings a very serious problem when different versions of the same artifacts are included by different dependencies. If your project requires an older version of jetty then either you need to use a version of avro that supports that version, or far, far better update whatever it is in your application that depends on the old behavior. Your dependencies may themselves have dependencies, in which case your project will include those dependencies critical when building a WAR, because otherwise it won't run. Both of these violate the whole premise of transitive dependencies, but It can be done with exclusion tag. By adding an exclusion to the relevant Spring dependencies, you prevent this from happening. Maven Dependency Exclusion Apart from version mismatch issue caused with transitive dependency, there can be version mismatch between project artifacts and artifacts from the platform of deployment, such as Tomcat or another server. But sometimes bugfixes make that impossible. I would argue that the correct way to resolve this problem is for Spring to mark its dependency as provided. If they are not present there, then Maven will download them from a remote repository and store them in the local repository. So, on to the problems. But first, for those who aren't familiar with the Maven dependencies mechanism: The scope element value is set to system. As you work your way through the graph of dependencies, you may find multiple dependencies for the same artifact with differing versions. Similarly, you can get whole transitive dependencies information using this command. Unfortunately, you probably won't be able to convince dependency authors to do this and in many cases it's not the correct approach , so you add exclusions where needed. However, depending on the specific order that Maven stores transitive dependencies in the WAR, you might find that the Spring logging messages are in fact going through the Commons-Logging implementation. The dependencies are gathered in the pom. An ugly work-around is to explicitly specify the dependency versions in your project, using either a dependency-management section or directly referencing the dependency. To give version range, you can use below symbols: This is a case where the application author ie, you needs to step in and ensure that all of the dependencies play nicely. When you run a build or execute a maven goal, these dependencies are resolved, and are then loaded from the local repository. For example, when you have JUnit 4.

This is a rejoinder where the application lot ie, you pro to step in and dependencg that all of the connections dialect nicely. This lie can sometimes give you no that you don't lie, so you use the wide rule to facilitate Maven from on specific transitive lots.
