I recently switched IDE’s to Eclipse.
Just to test that I am not insane, I added something like
import x;
to the top of the Java file. I was expecting to see the red squiggly line underlining the library the IDE can’t find, but it didn’t do it automatically.
How can I set the Eclipse setting to tell me if some syntax is wrong, or a library I am importing isn’t in place?
It should flag it as a compiler error automatically (including the squiggly line). You might need to convince it to rebuild the project. Are you automatically building the project, or doing it manually? Eclipse occasionally loses track of automatic rebuilds.
