Import cannot be resolved in java

Question

I am getting:

import com.test.foo.A cannot be resolved

IDE I am using is NWDS.

I have a class A which is declared as public, I have a class B which is declared as public final. Both are declared in different packages.

Class A in com.test.foo

Class B in com.test.foo1

I am trying to import a public method from class A to class B but I am getting the above mentioned error in IDE.

Both are in different projects.

Code snippet as below :-

package com.test.foo 

public class A {

    public static void method1(){
    ....some code ....
    }

}

-----

package com.test.foo1

import com.test.foo.A // i'm getting error here as import cannot be resolved

public final class B {

    private method2(){

    ...... some code....
     A.method1(); // import cannot be resolved error
    }
}

Can any help help on this?

Thanks in advance for you help :)

Please include the code where you are having the `import` failure. — Tim Biegeleisen, Jan 16 '17 at 12:46
Are they in same project? Of if different ones, is the dependency configured well? — Pavan Kumar, Jan 16 '17 at 12:52
@PavanKumar in different projects and dependency has been configured. — Neethu Shaji, Jan 16 '17 at 12:56
What is the directory structure of `A.java` and `B.java` ? Does it follow the package names exactly? — Tim Biegeleisen, Jan 16 '17 at 12:57
@NeethuShaji may be you can share the screenshot that depicts the folder structure. can you? — Pavan Kumar, Jan 16 '17 at 12:58
@TimBiegeleisen : Yes they follow the same package strtucture that is Class A is present in package com.test.foo of Project1 and Class B is present in package com.test.foo1 of Project2 I hope i am making myself clear :) Let me know — Neethu Shaji, Jan 16 '17 at 13:02
@PavanKumar : I am sorry i cannot share the exact code screenshot here. I can provide you with the details though :) — Neethu Shaji, Jan 16 '17 at 13:04
@NeethuShaji No, they have to share the same folder structure, meaning _both_ projects are in `test/com` — Tim Biegeleisen, Jan 16 '17 at 13:05

In your image you have the class ClassA not A.

So the error is:

 "import com.test.foo.A cannot be resolved"

You should import the class ClassA.

package com.test.foo1

import com.test.foo.ClassA;

public final class B {

  private method2(){

    //...... some code....
    ClassA.method1(); 
  }
}

Thanks you for the help :) that was a mistake from my end :( the screenshot i shared was just an example but for the actual code its still "Import cannot be resolved" in this case the solution is correct :) – Neethu Shaji Jan 16 '17 at 14:47

This is like trying to copy text by clicking "copy" button on a computer, and clicking "paste" button on another computer. Quite amusing. :-)

Well, a general Java way is you build the project that contains A as a JAR, and use it as a library in another project that contains B.
Or if you organize your project using Maven, you can import another project as dependency. Something like:

?

<project>
   ...
   <dependencies>
      <dependency>
         <groupId>yourgroup</groupId>
         <artifactId>myejbproject</artifactId>
         <version>2.0</version>
         <scope>system</scope>
         <systemPath>path/to/myejbproject.jar</systemPath>
      </dependency>
   </dependencies>
   ...
</project>

@kevin Wang thanks for your reply but this won't work we are not using MAVEN build. And i have already made the dependency clear :) – Neethu Shaji Jan 16 '17 at 13:06
@TimBiegeleisen, uh? would you elaborate why not? the problem he is facing is that class A is not in class path, so can be resolved. – Kevin Wang Jan 16 '17 at 13:08
I have the feeling that he is dealing with code that he wrote himself, and not external JARs, which therefore means code which won't be managed by Maven. – Tim Biegeleisen Jan 16 '17 at 13:10
@NeethuShaji, sorry I don't know about the IDE you're using, bottom line is you could go with the JAR way, which isn't ideal if you need to modify the classes in both projects. Maybe someone know the IDE also know a trick to get it work. Good luck. – Kevin Wang Jan 16 '17 at 13:12
@KevinWang i have attached the screenshot could you please have a look and let me know :) – Neethu Shaji Jan 16 '17 at 13:26
@NeethuShaji from the screenshot you posted it, yeah, it is ClassA, not just A. BTW, your IDE seems to me just good old Eclipse, is it called NWDS now? – Kevin Wang Jan 16 '17 at 14:10
@KevinWang Since i cannot post the screenshot of the actual code here. I tried wrote the same in Eclipse and pasted the screenshot. Also, yes that was a typo from my end about ClassA Sorry for that :( The actual code is written in NWDS IDE. – Neethu Shaji Jan 17 '17 at 02:11

Even if you imported the right class and still getting this error, use this trick.

Remove the import statement and re-import it.
