The import org.springframework.test.context.junit4.SpringRunner cannot be resolved

Question

I'm trying to resolve this from sometime now.But Still i didn't get it solved.I just downloaded a spring project form spring.io and just imported it as a Maven project to Eclipse IDE.After that i get this above mentioned error.

The import org.springframework.test.context.junit4 cannot be resolved

I have attached my code below.Together with the full pom.xml content.

package com.Ticket.Booking.TicketBooking;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;//I got the error in this line

@RunWith(SpringRunner.class)//Also in this line too.
@SpringBootTest
public class TicketBookingApplicationTests {

    @Test
    public void contextLoads() {
    }

}

Here's my pom.xml file.

Please help me to solve this issue.It's very much important for me as a student.

Answer 1

It could be the scope, which is set to test .

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-test</artifactId>
    <scope>test</scope>
</dependency>

Please make sure that the class that has the SpringRunner is in your /src/test/java folder.

Answer 2

I had the latest eclipse and also the latest junit 4.12 jar but still I use to get this problem. I finally fixed it. Follow these steps:

1. Close your maven project created in eclipse and close eclipse or STS tool.
2. Go to Maven repository:

C:\\Users\\.m2\\repository\\org\\springframework\\

and delete everything inside springframework folder.

3. Now open eclipse/STS tool and then open your project.
4. The project will build automatically and the error disappears.
5. If it doesn't then

right click on project -> Maven -> Update Project.. -> check the Force Update and click OK

Answer 3

I think a dependency is missing:

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-test</artifactId>
    <version>4.3.10.RELEASE</version>
    <scope>test</scope>
</dependency>

Answer 4

Why are your using a BUILD-SNAPSHOT?

In your pom.xml you have

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.0.0.BUILD-SNAPSHOT</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>

use version

<version>2.0.4.RELEASE</version>

or another RELEASE version.

Don't override library version unless is really necessary.
