Maven: Command to update repository after adding dependency to POM

Question

I\'ve added a new dependency to my POM.

Is there a simple command I can run to download this dependency to my repository?

Answer 1

Right, click on the project. Go to Maven -> Update Project.

The dependencies will automatically be installed.

Answer 2

Pay attention to your dependency scope I was having the issue where when I invoke clean compile via Intellij, the pom would get downloaded, but the jar would not. There was a xxx.jar.lastUpdated file created. Then realized that the dependency scope was test, but I was triggering the compile. I deleted the repos, and triggered the mvn test, and issue was resolved.

Answer 3

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.

Answer 4

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.

Answer 5

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=...
