Can any one please help me to resolve this problem..?

I even tried installing the gradle using below URL.

http://dist.springsource.com/snapshot/TOOLS/gradle/nightly (latest development snapshot)
http://dist.springsource.com/milestone/TOOLS/gradle (latest milestone build)
http://dist.springsource.com/release/TOOLS/gradle (latest release)

but all in vain.I will end up getting the following eror.

Unable to read repository at http://dist.springsource.com/snapshot/TOOLS/gradle/nightly/site.xml.

STS 3.1.0 is pretty old. Can you try using something recent (like the current version of STS which is 3.6.1)?

I'm getting this when trying to install from Eclipse Marketplace:

The following solutions are not available: Gradle Integration for Eclipse (4.4) 3.6.2.RELEASE (id=org.gradle.toolingapi.feature.feature.group, site=http://dist.springsource.com/release/TOOLS/update/e4.4/)

Try not including “org.gradle.toolingapi.feature”. I’m not sure why it’s there and what it does. The tooliapi plugin project and feature is included into “Gradle IDE” feature and this is probably the source of the error.
This issue is not preventing you from installing Gradle Eclipse plugin, correct? Or is it more serious than it looked to me?

Yeah, disabling that did the trick. It doesn't say "Optional", so I had it checked at first.
