In Maven, how output the classpath being used?

Question

For my current purposes I have a Maven project which creates a war file, and I want to see what actual classpath it is using when creating the war. Is there a way to do that in a single command -- without having to compile the entire project?

One idea is to have Maven generate the target/classpath.properties file and then stop at that point.

To get the classpath all by itself in a file, you can:

mvn dependency:build-classpath -Dmdep.outputFile=cp.txt 

Or add this to the POM.XML:

<project>   [...]   <build>     <plugins>       <plugin>         <groupId>org.apache.maven.plugins</groupId>         <artifactId>maven-dependency-plugin</artifactId>         <version>2.9</version>         <executions>           <execution>             <id>build-classpath</id>             <phase>generate-sources</phase>             <goals>               <goal>build-classpath</goal>             </goals>             <configuration>               <!-- configure the plugin here -->             </configuration>           </execution>         </executions>       </plugin>     </plugins>   </build>   [...] </project>
