Eclipse Mars - references wrong asm.jar

I’m using version of Gradle IDE in Eclipse Mars. The problem is that Gradle tries to locate asm-4.0.jar in old folder from a previous version.

Error is:
The container ‘Persisted container [org.springsource.ide.eclipse.gradle.dsld.classpathcontainer for project [myproject]]’ references non existing library ‘C:\Program Files\eclipse-4.4\plugins\org.springsource.ide.eclipse.gradle.toolingapi_3.6.4.201503050952-RELEASE\lib\asm-4.0.jar’

Looks as though you are using the Gradle integration provided by the Spring Tool Suite. The Springsource team is no longer actively developing the Gradle integration in STS. I suggest you look at using Buildship instead.
