Problem in resolving apigee-edge-maven-plugin dependencies

[#1]

I am using the Apigee Maven Deployment plugin to start with deploying the proxy on Apigee with maven. For this i just cloned the project and run the following commands in the project directory,

• cd samples/forecastweatherapi-recommended/src/gateway/forecastweatherapi
• mvn install -Ptest -Dusername={apigee-edge-email} -Dpassword={apigee-edge-password} -Dorg={apigee-edge-org}

And then i got the below error,

[ERROR] Plugin io.apigee.build-tools.enterprise4g:apigee-edge-maven-plugin:1.1.5 or one of its dependencies could not be resolved: Failed to read artifact descriptor for io.apigee.build-tools.enterprise4g:apigee-edge-maven-plugin:jar:1.1.5: Could not transfer artifact io.apigee.build-tools.enterprise4g:apigee-edge-maven-plugin:pom:1.1.5 from/to central (http://repo1.maven.org/maven2): repo1.maven.org: Temporary failure in name resolution: Unknown host repo1.maven.org: Temporary failure in name resolution -> [Help 1] [ERROR] [ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.

[ERROR] [ERROR] For more information about the errors and possible solutions, please read the following articles: [ERROR] [Help 1] http://cwiki.apache.org/confluence/display/MAVEN/PluginResolutionException

Can anyone help me resolve this ?
