How to set classpath in spring tool suite

I have added a g开发者_如何学JAVArails project to workspace and i want to set the classpath.how to do this. I am not able to find an option to set the classpath in project->properties.

If you are creating a grails project, you should be setting your classpath through grails, rather than through STS. I assume that you already have the Grails Tooling of STS installed.

The way that you alter a grails project's classpath depends on what you are trying to do. Please explain exactly what you are trying to do and I can perhaps be more specific.
