Spark Spark Dev

I`ve downloaded the latest Spark project and Smack libs. Also i had to download smakx libs not from ur sire. When i build i get an error:

java: cannot find symbol

symbol: class Connection

location: package org.jivesoftware.smack

Other classes are fine. Where can i can get this class?
Also i have these errors:

Error:(423, 42) java: cannot find symbol

symbol: class Connection

location: class org.jivesoftware.spark.ui.conferences.ConferenceServices

and Error:(40, 55) java: package org.lobobrowser.html.domimpl.HTMLElementBuilder does not exist

Where can i get all these libs?
Or where can i get the whole project with prelinked libs. I hope u understatnd me and will help.

Maybe i`ve imported project from wrong folder… But if i import project from the root (i mean downloaded) with all libs i also get a great amount of errors:
some about abstract classes like Error:(48, 8) java: org.jivesoftware.spark.ui.ReconnectPanelSmall is not abstract and does not override abstract method authenticated(org.jivesoftware.smack.XMPPConnection) in org.jivesoftware.smack.ConnectionListener
Some others… like

Error:(1766, 24) java: cannot find symbol

symbol: method setProperty(java.lang.String,boolean)

location: variable message of type org.jivesoftware.smack.packet.Message
Or

Error:(2395, 39) java: cannot find symbol

symbol: method getStreamError()

location: variable xmppEx of type org.jivesoftware.smack.XMPPException
And many others…
How can i solve all of them?
