Force re-download of release dependency using Maven

Question

I\'m working on a project with dependency X. X, in turn, depends on Y.

I used to explicitly include Y in my project\'s pom. However, it was not used and to make thin

Answer 1

When you added it to X, you should have incremented X's version number i.e X-1.2
Then X-1.2 should have been installed/deployed and you should have changed your projects dependency on X to be dependent on the new version X-1.2

Answer 2

I just deleted my ~/.m2/repository and that forced a re-download ;)

Answer 3

You cannot make Maven re-download dependencies, but what you can do instead is to purge dependencies that were incorrectly downloaded using mvn dependency:purge-local-repository

See: http://maven.apache.org/plugins/maven-dependency-plugin/purge-local-repository-mojo.html

Answer 4

I think following command may help you!

---

mvn -U clean install

Answer 5

Most answers provided above would solve the problem.

But if you use IntelliJ and want it to just fix it for you automatically, go to Maven Settings.

Build,Execution, Deployment -> Build Tools -> Maven

Disable Work Offline

Enable Always update snapshots (Switch when required)

Answer 6

If you know the group id of X, you can use this command to redownload all of X and it's dependencies

mvn clean dependency:purge-local-repository -DresolutionFuzziness=org.id.of.x

It does the same thing as the other answers that propose using dependency:purge-local-repository, but it only deletes and redownloads everything related to X.
