Maven and jar version in final artifact

I am starting with maven 2 and I have a jar version problem in my project. I have the following dependency declared in mine pom.xml

:

<dependency>
  <groupId>commons-logging</groupId>
  <artifactId>commons-logging</artifactId>
  <version>1.1.1</version>
</dependency>

But when I build my war, I get version 1.0.3 of this artifact. How is this possible !? Also, version 1.1.1 is available in my repository.

How do you know where it came from?

I am the new developer of this project. The parent pom declares this version, the war pom inherits from the parent pom.

You will probably end up with a transitive dependency (i.e. you have a dependency on an artifact that has commons-logging-1.0.3.jar as a dependency, and you get it from that artifact). To check where it came from, you can print the "dependency tree" using the Maven Dependency Plugin (can also find conflicts ):

mvn dependency:tree


Now, to solve the problem and control the versions used in transitive dependencies, the solution would be to declare your dependency in dependencyManagement

:

<dependencyManagement>
  <dependencies>
    <dependency>
      <groupId>commons-logging</groupId>
      <artifactId>commons-logging</artifactId>
      <version>1.1.1</version>
    </dependency>
  </dependencies>
</dependencyManagement>
