How to get snapshot from Sonatype

问题

I'm trying to get the snapshot release for atmosphere that is available for org.atmosphere and can't seem to get it...

<repositories>
    <!-- Added to get the Atmosphere 1.1.0-SNAPSHOT, can be removed when 1.1.0 is released -->
    <repository>
        <id>oss.sonatype.org-snapshot</id>
        <url>http://oss.sonatype.org/content/repositories/snapshots</url>
        <releases><enabled>false</enabled></releases>
        <snapshots><enabled>true</enabled></snapshots>
    </repository>
</repositories>

There are no atmosphere versions that appear to be picked up by adding the new repository.

<dependency>
    <groupId>org.atmosphere</groupId>
    <artifactId>atmosphere-runtime</artifactId>
    <version>1.1.0-SNAPSHOT</version>
    <exclusions>
        <exclusion>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-api</artifactId>
        </exclusion>
    </exclusions>
</dependency>

I'm told by the primary atmosphere developer that this should work

Works fine for me. What error are you getting?

pom.xml

<?xml version="1.0"?>
<project>
  <modelVersion>4.0.0</modelVersion>
  <groupId>org.example</groupId>
  <artifactId>example</artifactId>
  <version>1.0</version>
  <repositories>
    <!-- Added to get the Atmosphere 1.1.0-SNAPSHOT, can be removed when 1.1.0 is released -->
    <repository>

      <url>http://oss.sonatype.org/content/repositories/snapshots</url>
      <releases>
        <enabled>false</enabled>
      </releases>
      <snapshots>
        <enabled>true</enabled>
      </snapshots>
    </repository>
  </repositories>
  <dependencies>
    <dependency>
      <groupId>org.atmosphere</groupId>

Remove content of $HOME/.m2/repository/org/atmosphere/cpr and try again :)
