Eclipse JUnit - possible causes of seeing “initializationError” in Eclipse window

Question

I know this question is pretty general but I haven\'t found any hints on why this error may show up. What are possible causes of seeing initalizationError in Eclips

Answer 1

In my case I have changed project name in pom.xml so the new target directory was generated and junit was searching classes in old directory. You need to change directory for JUnit also in Eclipse

Properties -> Java Build Path -> Source (Default output folder)

And also check because some of source folders listed in the same window may have former directory name. You need to change them too.
