Description

When using the unpack goal with Java 1.5 or 1.6, the following error message will appear:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-dependency-plugin:2.10:unpack (unpack) on project ID-JRE_8.0: Execution unpack of goal org.apache.maven.plugins:maven-dependency-plugin:2.10:unpack failed: An API incompatibility was encountered while executing org.apache.maven.plugins:maven-dependency-plugin:2.10:unpack: java.lang.NoSuchMethodError: java.io.File.toPath()Ljava/nio/file/Path;

This is obviously calling a method introduced in Java 7. This contradicts the about page[1] that indicates that JDK 1.5 is the minimum required.

This bug does not appear until version 2.10. Version 2.9 works fine.
