obtain the location of a jar that is a dependency in maven

Question

I have a project that uses some legacy script for processing the source code. I cannot get rid of it, so I want to call it from maven.

the problem is that I need to pass as an argument the location of a jar file. I have listed this jar file as a dependency in my pom.xml. is there a way that I can pass the absolute location of the jar file to this script?

This isn't by any means ideal, but you could call your script from maven, and pass this in as a parameter:

${settings.localRepository}/<path to artifact>

where path to artifact is a path made up of the group id and artifact id you want. Example, if you wanted a reference to the maven-jar-plugin version 2.2, you'd use this:

${settings.localRepository}/org/apache/maven/plugins/maven-jar-plugin/2.2/maven-jar-plugin-2.2.jar

Yeah, what you're doing is really unconventional, so this isn't ideal at all. The better plan would be to mavenize those legacy scripts so you no longer need them ;) – Michael Mar 08 '12 at 13:09

I like Pascal Thivent's answer to a similar question better. You can refer to dependencies with the ${maven.dependency.junit.junit.jar.path} notation. Pascal includes a sample pom in his answer:

<?xml version="1.0" encoding="UTF-8"?>
<project>
  <modelVersion>4.0.0</modelVersion>
  <groupId>com.stackoverflow</groupId>
  <artifactId>q2359872</artifactId>
  <version>1.0-SNAPSHOT</version>
  <name>q2359872</name>
  <properties>
    <my.lib>${maven.dependency.junit.junit.jar.path}</my.lib>
  </properties>
  <dependencies>
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>3.8.1</version>
      <scope>test</scope>
    </dependency>
  </dependencies>
  <build>
    <plugins>
      <plugin>
        <artifactId>maven-antrun-plugin</artifactId>
        <executions>
          <execution>
            <phase>process-resources</phase>
            <configuration>
              <tasks>
                <echo>${my.lib}</echo>
              </tasks>
            </configuration>
            <goals>
              <goal>run</goal>
            </goals>
          </execution>
        </executions>
      </plugin>
    </plugins>
  </build>
</project>

apparently this only works when using antrun plugin, which is not my case — santiagozky, Mar 28 '12 at 12:09
