Cannot import java classes under src / main / java in src / test / java in eclipse

Question

I am using the maven project in Eclipse, where I cannot access the classes in src / main / java in the src / test / java class. However, I could use classes in maven databases. What am I missing?

Answer 1

I found that sometimes this error appears and, simply by going to Project -> Clean... , the error stops.

However, if this does not work, there is a blog with a few suggestions here

Or just all of them here.

• 'Clean up the Eclipse project: go to Project> Clean in Eclipse [This seems to work for me]
• Update the project folder (right click on your project> update)
• Restore your project
• Clean your builds (if using Ant or Maven - clean your builds)
• Create a new project in Eclipse
• 'Switch workspace - then switch (for example, "Change to debug", then return to Java)
• Remove and re-add the JRE:
  • Right click on your project> properties
  • Go to the Libraries tab
  • Click JRE
  • Click Delete, then OK.
  • Repeat 1-3 again, but add the JRE again.

Answer 2

You just need to import them. Eclipse should help you with this: if you try to use class names, it will suggest where to import it from.

Test classes are a separate package, so classes must be declared public .

Answer 3

Project → Clear

enough for me to work
