I'm not aware of such a tool.
You can use the maven-dependency-plugin and inject the following snippet in your pom.xml
:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<version>2.10</version>
<executions>
<execution>
<id>copy-dependencies</id>
<phase>process-resources</phase>
<goals>
<goal>copy-dependencies</goal>
</goals>
<configuration>
<outputDirectory>${project.build.directory}/target/libs</outputDirectory>
<overWriteReleases>false</overWriteReleases>
<overWriteSnapshots>false</overWriteSnapshots>
<overWriteIfNewer>true</overWriteIfNewer>
</configuration>
</execution>
</executions>
</plugin>
Then, take this pom and run maven:
mvn clean process-resources
Run it outside your problematic network.
All dependencies will be resolved and copied to ${project.build.directory}/target/libs
I hope this helps.
