Can I use the path to a Maven dependency as a property?
maven-2
Solution
Assuming that the `com.foo:Bar:jar:1.2.3` artifact is declared as dependency in your POM, the following property returns the path to the jar in the local repository:
${maven.dependency.com.foo.Bar.jar.path}
Update: Here is a simple POM demonstrating this:
<?xml version="1.0" encoding="UTF-8"?>
<project>
<modelVersion>4.0.0</modelVersion>
<groupId>com.stackoverflow</groupId>
<artifactId>q2359872</artifactId>
<version>1.0-SNAPSHOT</version>
<name>q2359872</name>
<properties>
<my.lib>${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>
Running `mvn process-resources` produces the following output:
$ mvn process-resources

Problem
I have a maven dependency in my pom.xml as such: ``` <dependency> <groupId>com.foo</groupId> <artifactId>Bar</artifactId> <version>1.2.3</version> </dependency> ``` And I would like to use the system path to the binary as a property (so I can pass it to an external process that is kicked off by maven). I can do this in an awkward way: ``` <properties> <my.lib>${settings.localRepository}/com/foo/Bar/1.2.3/Bar.jar</my.lib> </properties> ``` But I would really like to use a more standard mechanism, such as: ``` <properties> <my.lib>${com.foo:Bar:1.2.3}</my.lib> </properties> ``` I something like that possible?
