Projects will not build or run due to an error, cause is not understood. It would appear the that path is being truncated at the "@" in the user path (user name is "Paul F@!nt Marshall"). This is not an issue of the project that is being attempted to be built or run, as there are no issues on other machines or other user profiles on the same machine, so it seems to be a NetBeans issue. This was not an issue until only a couple days ago. Similar behavior has been seen on a path that had an apostrophy "'" in the path: example is "Alec's Projects". The path would truncate at "Alec" and fail.

It is likely that the Ant core is misinterpreting the '!' in the pathname as the separator in a jar-protocol URL. Apostrophes are also likely to cause problems for build scripts which need to represent absolute file paths, as they are subject to misinterpretation as shell quotes, especially when launching subprocesses.
Avoid placing projects, or your NetBeans installation or user directory, under paths which use punctuation characters (other than '.', '_', or '-') to avoid this kind of problem.
most likely ant issue https://issues.apache.org/bugzilla/show_bug.cgi?id=50007 is related
ant's 50007 issue comment mentions that the recent versions of Ant (that we ship) should be able to handle ! character as long as it's not the last char in the directory name.
closing as fixed (as we likely fixed this by upgrading ant),
please verify and reopen if still not working
