Cannot read jenkins maven dependencies - maven

Question

I am trying to get this demo application up and running on my machine:
https://github.com/jenkinsci/cli-channel-demo
I have this in my pom:
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>org.jenkins-ci.demo</groupId>
<artifactId>cli-channel-demo</artifactId>
<version>1.0-SNAPSHOT</version>
<packaging>jar</packaging>
<name>cli-channel-demo</name>
<url>http://maven.apache.org</url>

<repositories>
<repository>

<url>http://repo.jenkins-ci.org/public/</url>
</repository>
</repositories>
<dependencies>
<dependency>
<groupId>org.jenkins-ci.main</groupId>
<artifactId>cli</artifactId>
<version>1.415</version>
</dependency>
<dependency>
<groupId>commons-io</groupId>
<artifactId>commons-io</artifactId>

</dependency>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>3.8.1</version>
<scope>test</scope>
</dependency>
</dependencies>
</project>
But I get this error:
The POM for org.jenkins-ci.main:cli:jar:1.415 is missing, no dependency information available
even though the dependency is located right here:
http://repo.jenkins-ci.org/public/org/jenkins-ci/main/cli/1.415/
and I have this in my pom:
<repositories>
<repository>
<id>repo.jenkins-ci.org</id>
<url>http://repo.jenkins-ci.org/public/</url>
</repository>
</repositories>
Why can't maven resolve this dependency on my local machine?

Answer 1

Worked fine on my machine. I think you need to supply some more details of your error.
Common issues are:
Network proxy denying direct access to internet
Mirror configuration pointing builds at a local Maven repository
See the Maven settings reference for more details on how these issues could be fixed.
