RapidMiner5-extension-project build failed with one line more code.
I am using RM5 and want to add extension to RM5.
So I download rapidminer5's extension project.
But I met a very strange problem.
This is the beginning of the situation, I added a class and an empty method, the compilation passed.
But when I add a line of code, the compilation doesn't go through. This line of code is very common, just a code to create an object. I don't know why the compilation failed.
just add one linethe extension folder is missing
