Cannot build from source

I am trying to build autopsy from source using netbeans but the compiler cannot download the file${netbeans-plat-version}/tasks.jar. I have tried to visit the page directly to see if it up using the netbeans-plat-version 11.3 but it doesn’t seem to exist.

Is there another location of where to download this file and others such as the updates.xml.gz etc and I can edit the .properties file.
