Right-click a NetBeans Platform application project and choose Properties and then in the Libraries tab you'll see warning messages at the bottom like this one:
"Module net.java.html.boot.fx in platform requests the token javafx.application but there are no known providers."
After unchecking the above module, there's another message like the above, altogether about 10 modules need to be unchecked before the warning message disappears.
1. Is confusing and looks like there's something wrong.
2. Prevents the red "Resolve" button from becoming enabled, i.e., blocks me from automatically resolving dependencies related to those I have already selected.
