Maven pom error

Question

I have example projects from spring core training courses I've been on. They did work on their machines, not on mine though. I am not really expert with maven, but .pom file inside gives this error. I really appreciate any monkey-alike-instructions, I'l do first then understand. Thank you very much in advance. I just want to run them and go through again.

Project build error: Non-resolvable parent POM: Failure to transfer com.springsource.training.common:abstractWebProject:pom:1.1.7.RELEASE from https://tbits.springsource.com/repository/snapshot was cached in the local repository, resolution will not be reattempted until the update interval of com.springsource.training.snapshot has elapsed or updates are forced.

Original error: Could not transfer artifact com.springsource.training.common:abstractWebProject:pom:1.1.7.RELEASE from/to com.springsource.training.snapshot (https://tbits.springsource.com/repository/snapshot): ConnectException and 'parent.relativePath' points at wrong local POM pom.xml /mvc-1-solution line 1 Maven Problem

plus I am having numerous mistakes for missing libraries: Description Resource Path Location Type

Project 'mvc-1-solution' is missing required library: 'C:\Users\Blabla\.m2\repository\org\cloudfoundry\cloudfoundry-runtime\0.6.0-BUILD-SNAPSHOT\cloudfoundry-runtime-0.6.0-BUILD-SNAPSHOT.jar' mvc-1-solution      Build path  Build Path Problem

and many more alike.

Their .pom file.

Answer 1

"..resolution will not be reattempted until the update interval of com.springsource.training.snapshot has elapsed or updates are forced." --This is due to the first failure trying to download artifacts, need to remove those *.lastUpdated from your repository.

For windows:

cd %userprofile%.m2\repository for /r %i in (*.lastUpdated) do del %i

Answer 2

Not a solution, but a recipe how to solve it:

• Check each of the repositories you have defined in the Maven POM. For me, the 2 springsource repos are not available at the moment.
• I think that the abstractWebProject will be contained in some of these. So the error Project build error: Non-resolvable parent POM: Failure to transfer will be a result of that.
• After you may have access to the parent POM, you should check if all the dependencies are resolvable.
• If everything fails, get in touch with the training team. If you were on that training, they will try to help you. You should have then the following information ready available:
  • The POM you want to use (as in your question)
  • The file settings.xml in your Maven installation
  • The version of your Maven isntallation
  • The file settings.xml in your user directory .m2 (depending on your operating system at different locations).

Hope you can get the help you need to solve it.
