• Type: Bug

Description

This is the extension I am using:

<extensions>
		<extension>
			<groupId>org.springframework.build.aws 
			</groupId>
			<artifactId>org.springframework.build.aws.maven 
			</artifactId>
			<version>2.0.0.RELEASE</version>
		</extension>
</extensions>

It is being taken from this repository:

		<repository>
			<id>spring-snapshot</id>
			<name>Spring Portfolio Snapshot Repository</name>
			<url>http://s3.amazonaws.com/maven.springframework.org/snapshot</url>
		</repository>

And depends on httpclient-3.1, which in turn depends on commons-logging 1.0.4.

When I try to mvn dependency:copy and there is a dependency that needs to be resolved from s3 I get the following exception:

[ERROR] FATAL ERROR
