I've recently imported a Maven project into Eclipse, but none of the syntax highlighting is working. Additionally, when I try to write any code to any of the files (System.out.print("") for example), a dialog box appears saying "This compilation unit is not on the build path of a Java project". This is likely the reason this is happening. How can I fix this?

I've tried the solutions suggested in the following threads to no avail:

"This compilation unit is not on the build path of a java project" -Eclipse

Eclipse "this compilation unit is not on the build path of a java project"

This compilation unit is not on the build path of a Java project

Do you have these lines in the .project file of the project folder : ` org.eclipse.jdt.core.javanature org.eclipse.m2e.core.maven2Nature ` – veben Sep 05 '18 at 16:45
Yes, those two lines are in the .project file. But the error persists. – kramsiv94 Sep 05 '18 at 16:51

This sounds like you are editing a Java file outside a source folder. – howlger Sep 05 '18 at 19:27
