I am using Eclipse based development environment - a Groovy/Grails Tool Suite. The issue seems to be that eclipse is not able to find some JARs. And I dont understand where to put those JARs. Below are the details.
I am trying to step through the code. However when I put watch on any variable it gives error, but the same variable evaluates correctly on Variables window. I did one obeservation, that when there are a lot of expressions in my Expressions window, the debugger slows down, it takes time to evaluate those expressions but gives error for all. When I remove all expressions it steps through without any slow down. Also similar error occur when I use Display window
Below is the screen shot of whats happening

I checked the eclipse error log file. There are many errors, but below seems to be relevant one:

Seems like it needs some jars, but which and where to put them? I tried adding the file slf4j-api-1.7.2.jar which contains these classes to %JAVA_HOME%/lib and %JAVA_HOME%\jre\lib and also to ggts' plugins folder, but it did not helped.
