Maven: Command to update repository after adding dependency to POM

mvn install (or mvn package) will always work.

You can use mvn compile to download compile time dependencies or mvn test for compile time and test dependencies but I prefer something that always works.

If you want to only download dependencies without doing anything else, then it's:

mvn dependency:resolve

Or to download a single dependency:

mvn dependency:get -Dartifact=groupId:artifactId:version

If you need to download from a specific repository, you can specify that with -DrepoUrl=...

I know it is an old question now, but for users who are using Maven plugin with Eclipse under Windows, you have two options:

1. If you got Maven installed as a standalone application:

   You can use the following command in the CMD under your project path:

   mvn eclipse:eclipse
   

   It will update your repository with all the missing jars, according to your dependencies in your pom.xml file.

2. If you haven't got Maven installed as a standalone application you can follow these steps on your eclipse:

   Right click on the project ->Run As -- >Run configurations.

   Then select mavenBuild.

   Then click new button to create a configuration of the selected type .Click on Browse workspace then select your project and in goals specify eclipse:eclipse

You can refer to how to run the command mvn eclipse:eclipse for further details.
