I run this on a project content java source file virtual file:
R1 one is empty (no surprise here)
R2 & R3 point to the output root of the project. Is it what a orderEntry is? With a name like orderEntriesForFile I thought it would give me the compiled class file path. Is there a way to do that?
R4 is null! That is a very big surprise. Why would it? Why not have R4 returns the same as R2/R3? Is it supposed to work like that?
Next a question Q1:
is the multiple OrderEntry for multi-module project? Is there at most one OrderEntry per module per file?
