problem when using maven repository

[stece]

Hi all

I'm having a tough time trying to use the maven repository of oauth.

i've added this to my pom.xml

<dependency>
 <groupId>org.springframework.security.oauth</groupId>
 <artifactId>spring-security-oauth</artifactId>
 <version>1.0.0.M4</version>
</dependency>

but when netbeans tries to download the repo it allways gives me an error:

java.lang.AbstractMethodError
	at org.sonatype.aether.connector.wagon.WagonRepositoryConnector.connectWagon(WagonRepositoryConnector.java:310)
	at org.sonatype.aether.connector.wagon.WagonRepositoryConnector.pollWagon(WagonRepositoryConnector.java:378)
	at org.sonatype.aether.connector.wagon.WagonRepositoryConnector$GetTask.run(WagonRepositoryConnector.java:578)
	at org.sonatype.aether.util.concurrency.RunnableErrorForwarder$1.run(RunnableErrorForwarder.java:64)

	at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908)
[catch] at java.lang.Thread.run(Thread.java:680)

hope someone can help
kind regards

UPDATE: it can't be the network/firewall. An other pc in the network doesn't have the problem and we tried to connect this pc to another wifi and it still doesn't work. :s

We made an empty pom project and added the dependecies there. It started downloading without a problem and now our main project works. :s

WEIRD!
