Maven 3 and JUnit 4 compilation problem: package org.junit does not exist

Question

I am trying to build a simple Java project with Maven. In my pom-file I declare JUnit 4.8.2 as the only dependency. Still Maven insists on using JUnit version 3.8.1. How do

Answer 1

Me too had the same problem as shown below.

To resolve the issue, below lines are added to dependencies section in the app level build.gradle.

compile 'junit:junit:4.12'
androidTestCompile 'com.android.support.test:runner:0.5'

Gradle build then reported following warning.

Warning:Conflict with dependency 'com.android.support:support-annotations'. 
Resolved versions for app (25.1.0) and test app (23.1.1) differ. 
See http://g.co/androidstudio/app-test-app-conflict for details.

To solve this warning, following section is added to the app level build.gradle.

configurations.all {
    resolutionStrategy {
        force 'com.android.support:support-annotations:23.1.1'
    }
}

Answer 2

Changing the junit version fixed this for me. Seems like version 3.8.1 didn't work in my case. Issue fixed upon changing it to 4.12

Answer 3

My case was a simple oversight.

I put the JUnit dependency declaration inside <dependencies> under the <dependencyManagement/> node instead of <project/> in the POM file. Correct way is:

<project>
<!-- Other elements -->
    <dependencies>
    <!-- Other dependencies-->
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>4.11</version>
        </dependency>
    </dependencies>
<project>

Answer 4

Just to have an answer with the complete solution to help the visitors:

All you need to do is add the junit dependency to pom.xml. Don't forget the <scope>test</scope>

<dependency>
  <groupId>junit</groupId>
  <artifactId>junit</artifactId>
  <version>4.11</version>
  <scope>test</scope>
</dependency>

Answer 5

Add this dependency to your pom.xml file:

http://mvnrepository.com/artifact/junit/junit-dep/4.8.2

<!-- https://mvnrepository.com/artifact/junit/junit-dep -->
<dependency>
    <groupId>junit</groupId>
    <artifactId>junit-dep</artifactId>
    <version>4.8.2</version>
</dependency>

Answer 6

removing the scope tag in pom.xml for junit worked..
