Description

With the 2.0.0 tag of the hop-web container, when I use Tools --> Generate a Hop fat jar, it fails because it cannot find a directory named libswt/linux/x86_64

If I create that directory (empty) inside the container, in /usr/local/tomcat, the JAR is generated (although it looks like it is missing some JARs that are required for Dataflow; I am reporting that problem in a separate issue).

Full stacktrace below:
