This error occurs when your current directory is not the launch4j directory, as Leo noted.

Launch4j attempts to find its own install directory by looking on the classpath for launch4j.properties. This is done in Util.java, at the top of the getJarBaseDir() method. It was changed recently to have these lines:

URI uri = new URI(Util.class.getClassLoader()
    .getResource(Launch4jProperties)
    .getFile());

String path = uri.getPath();

if (path.startsWith("file:")) {
  String jarPath = path.substring(5,path.lastIndexOf('!'));

The problem is uri.getPath() does not return the "file:" part for local file URIs--it only returns the path portion of the URI beginning with /. I changed those last two lines to this, and it started working:

if (path.startsWith("/")) {
  String jarPath = path.substring(0, path.lastIndexOf('!'));

Note the 5 -> 0 in substring because we don't need to remove "file:" part anymore. I had to rename build.xml.prod to build.xml in order to compile launch4j, but other than that it worked fine.
