Frege can't find classes in referenced project or external jar

I think I'm making a simple mistake here, but I can't get Frege to find any classes outside of the local Eclipse project.

I have a working non-trivial Java project (that's not mine), that I do not want to modify. I want to have a new clean Frege enabled project that makes use of classes from the original project.

I tried marking the original project as a dependency of my Frege project, and I tried packaging the original project into a JAR, and listing the JAR as an external dependency of the Frege project. In both cases, a Java file in the Frege project can access the classes, but the Frege compiler says "class org.foo.bar.Class is not a known Java class". This seems like a bug, but I am not confident that I have not missed a simple configuration step.

I have not tried setting arguments in the project configuration as I wouldn't know what to set.

I did quickly discover that I can make a new Java file in the Frege project with a blank subclass of whatever class I need and use that in a Frege file. I have successfully compiled and run a simple program like this. The program just makes a new object, gets a field, and prints the correct value, so I believe my Frege is installed and working properly.

It should be enough to have your library listed in the build path and under "Referenced Libraries". Your recent comment indicates that the compiler does indeed find the class in question.

However, when you have an open editor tab it will not take notice of changed dependencies. Also, especially in recent eclipse versions I have observed that resolved error markers are sometimes not cleaned up correctly.

Please close the editor tab that has the false errors shown, and reopen it.
