Resolve ranges

A pom may specify version ranges for certain dependencies.

<dependencies>

  <dependency>
    <groupId>org.apache.maven</groupId>
    <artifactId>maven-project</artifactId>
    <version>[2.0.7, 2.0.9)</version>
  </dependency>
  
  <dependency>
    <groupId>org.codehaus.plexus</groupId>
    <artifactId>plexus-utils</artifactId>
    <version>[1.5.0, 1.5.1 ]</version>
  </dependency>
  
  <dependency>
    <groupId>junit</groupId>
    <artifactId>junit</artifactId>
    <version>[3.0, 3.8.2)</version>
  </dependency>
  
</dependencies>

Using the resolve-ranges goal, the version ranges can be set to the specific version used in the build.

mvn versions:resolve-ranges

The pom dependencies are modified to look like the following.

<dependencies>

  <dependency>
    <groupId>org.apache.maven</groupId>
    <artifactId>maven-project</artifactId>
    <version>2.0.8</version>
  </dependency>
  
  <dependency>
    <groupId>org.codehaus.plexus</groupId>
    <artifactId>plexus-utils</artifactId>
    <version>1.5.1</version>
  </dependency>
  
  <dependency>
    <groupId>junit</groupId>
    <artifactId>junit</artifactId>
    <version>3.8.1</version>
  </dependency>
  
</dependencies>

You can restrict which dependencies should have their ranges collapsed. For example, the following will only match dependencies that match the groupId “org.codehaus.plexus” and artifactId “plexus-utils”

mvn versions:resolve-ranges -Dincludes=org.codehaus.plexus:plexus-utils

The includes and excludes parameters follow the format groupId:artifactId:type:classifier. Use a comma separated separated list to specify multiple includes. Wildcards (*) can also be used to match multiple values.

This example will match anything with the groupId “org.codehaus.plexus” and anything with the groupId and artifactId matching “junit”.

mvn versions:resolve-ranges -Dincludes=org.codehaus.plexus:*,junit:junit

By default, both the project/dependencyManagment and project/dependencies sections will be processed. You can use the processDependencies and processDependencyManagement parameters to control which sections are processed.

This example will only process the project/dependencyManagment section of your pom:

mvn versions:resolve-ranges -DprocessDependencies=false

While this example will only process the project/dependencies section of your pom:

mvn versions:resolve-ranges -DprocessDependencyManagement=false
