Setup the local development environment

I am pretty new to spring framework. When I tried to setup the local development environment, getting errors like (around 19 errors),

1.CsvCard cannot be resolved to a type
2.Failure to transfer com.tecnoteca:sencha-maven-plugin:pom:1.0-SNAPSHOT from was cached in the local repository
3.The method sendMessageSafe(ClusterMessage) of type new ClusteringService(){} must override or implement a supertype method
4.The method expandAttributePermissions(Map<PermissionScope,Set>) in the type DaoPermissionUtils is not applicable for the arguments (Map<PermissionScope,Object>)
5.The type new ClusteringService(){} must implement the inherited abstract method ClusteringService.getClusterNodes()

I got this source code from git, . And I already installed additional libraries. When I tried to open this project in STS, getting those errors. Please help me!!
