I have Eclipse Juno installed on my new MacBook Air Yosemite. I have imported a project I was working on in my old Mac and I need to add a reference to a new Jar. Trouble is, nothing happens when I click on the Add External JARs!
Eclipse is up-to-date. It appears it's just broken and may have something to do with Yosemite - I created a new project and cannot add any external JARs in that project either.
There is a work-around by putting the jars directly into the project's lib folder. But, this creates duplicate file system objects.
Please advise
This is the entry in Eclipse error log:
