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

Question

I am using maven project in Eclipse, where I am not able to access classes under src/main/java in src/test/java class. I could use the classes in maven dependacies jars though. What am I missing ?

Answer 1

I have found that sometimes this error appears and by simply going Project -> Clean... the error will stop.

However if this does not work there is a blog with some more suggestions here

Or just have them all here..

• 'Clean' Your Eclipse Project: Go to Project > Clean in Eclipse [This seems to work for me]
• Refresh your project folder (right click on your project > refresh)
• Re-build your project
• Clean your builds (If using Ant or Maven – clean your builds)
• Recreate your project in Eclipse
• 'Switch' Workspace – then Switch back (Eg Change to Debug, then switch back to Java)
• Remove and re-add your JRE:
  1. Right Click on your project > properties
  2. Click on the Libraries tab
  3. Click on the JRE
  4. Click remove, then OK
  5. 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 the class names, it'll suggest where to import from.

The test classes are a separate package, so the classes will need to be declared public .

Answer 3

Absolutely, one can do it..

First You need to navigate to Build Path-->Configure Build Path--> Source tab

then in the Source tab search/check [your Project Name]/src/main/java and change

"contains test sources" from No to Yes and save it.

This will resolved issue of import packages from "src/test/java" to "src/main/java" successfully

Answer 4

Project -> Clean

is enough for me to work
