Message #19972
Re: Developing with Scala/Java on OpenStack Swift
I copy this to the list because somebody can have similar issues
-----
Actually I think the issue is sbt ... (It seems that is not resolving
transitive dependencies)
First: Look and check if you added
https://maven.java.net/content/repositories/snapshots
https://raw.github.com/woorea/maven/master/snapshots
as maven repositories
A dirty way (but can help you):
<dependency>
<groupId>org.glassfish.jersey.core</groupId>
<artifactId>jersey-client</artifactId>
<version>2.0-SNAPSHOT</version>
</dependency>
<dependency>
<groupId>org.glassfish.jersey.media</groupId>
<artifactId>jersey-media-json-jackson</artifactId>
<version>2.0-SNAPSHOT</version>
</dependency>
<dependency>
<groupId>org.codehaus.jackson</groupId>
<artifactId>jackson-jaxrs</artifactId>
<version>1.9.8</version>
</dependency>
<dependency>
<groupId>org.codehaus.jackson</groupId>
<artifactId>jackson-xc</artifactId>
<version>1.9.8</version>
</dependency>
