maven- not downloading new added dependency in pom.xml file

Question

I need new third party jar for reading csv in maven based project. So, I did entry in pom.xml for same as below.

<dependency>
        <groupId>net.sf.opencsv</groupId>
        <artifactId>opencsv</artifactId>
        <version>2.0</version>
    </dependency>

But when I run mvn install or mvn package command, It does not download newly added dependency and just build project and generate war.

I am trying to get the issue! Please share solution if anybody face this earlier!

Regards

Answer 1

Try running a forced update:

mvn clean install -U

The -U (uppercase U) forces maven to look at all dependencies and try to update them.

Answer 2

If the dependency is defined in a <dependencies> block that is within a <dependencyManagement> block, adding it without the version number to a <dependencies> block that is outside <dependencyManagement> may fix the problem.

This is because the purpose of <dependencyManagement> block is to manage dependency versions, and not to install the dependencies. See this other article: Differences between dependencyManagement and dependencies in Maven
