I have downloaded the newest community version of the Alfresco - 5.0.d and installed it. I wasn't able to start Tomcat so I wanted to install it from the instructions listed on the following page: https://wiki.alfresco.com/wiki/Updated_information_on_building_and_running_Alfresco, however when I run mvn install I get the following error: "Caused by: org.apache.maven.project.DependencyResolutionException: Could not resolve dependencies for project org.alfresco:share-po:jar:5.1-SNAPSHOT: Failure to find org.alfresco.services.sync:service-synchronization-api:jar:1.0-SNAPSHOT in https://artifacts.alfresco.com/nexus/content/repositories/public-snapshots/ was cached in the local repository, resolution will not be reattempted until the update interval of alfresco-public-snapshots has elapsed or updates are forced at org.apache.maven.project.DefaultProjectDependenciesResolver.resolve(DefaultProjectDependenciesResolver.java:198) at org.apache.maven.lifecycle.internal.LifecycleDependencyResolver.getDependencies(LifecycleDependencyResolver.java:195) … 22 more" so as far as I can see the problem is with the repository https://artifacts.alfresco.com/nexus/content/repositories/public-snapshots/ and the following jar: org.alfresco.services.sync:service-synchronization-api:jar:1.0-SNAPSHOT. I think that there might be some other issues with the other libraries in the further steps. How can I reslove it?
