I just started to build and package my Compose desktop project on Windows for the first time. The build failed because of some missing wix tools. I noticed in the logs that downloading these tools was skipped for some reason. So what is the current state of the system? Am I supposed to manually download and install these things or should they be installed automatically and something is going wrong here?

They should be installed automatically. Will "./gradlew clean" prior the package task help?

I tried it again today and ran a clean as you suggested and it worked without doing anything else. I don’t know whether this is normal but at least I got it working. Maybe there is a timing or threading problem so that it does not work initially after the download because I did not try it a second time yesterday.
