How to import/add libraries into Spring STS?

Question

I am having an issue with Spring STS. I'm receiving the following messages:

This one when trying to download the template projects:

"Error while downloading or parsing descriptors file 'https://raw.github.com/SpringSource/spring-integration-templates/master/si-sts-templates/builds/descriptor.xml':

org.eclipse.core.runtime.CoreException: Error while retrieving https://raw.github.com/SpringSource/spring-integration-templates/master/si-sts-templates/builds/descriptor.xml"

...and this one when I check for updates:

"Some sites could not be found. See the error log for more detail. No repository found at http://download.eclipse.org/tools/gef/updates/releases/site.xml. No repository found at http://geronimo.apache.org/devtools/. Unable to read repository at https://dl-ssl.google.com/android/eclipse/content.xml. java.util.NoSuchElementException"

also, see the attachment for a screen shoot of how the tool suite will not import java.whatever and/or org.springframework.whatever

I believe that all three of these issues are related however, I can't prove or fix it.

Answer 1

There are some possible things to be checked in here,
1. Are you under some kind of proxy?
2. Did you download Spring STS directly or updated eclipse?
3. If your Spring STS is not working properly, you can download latest eclipse and use this link as update site.
4. You can check your project classpath also to just cross confirm that you are not missing anything up there.
