Working with code E015

If you receive the output code E015, this means that an error occurred when Diffblue Cover tried to download the junit-platform-launcher artifact. This prevents Diffblue Cover from validating the created tests. There are two ways to solve this problem:

  • Please make sure an internet connection is available
  • Use the maven-surefire-plugin or add a dependency to junit-platform-launcher, as shown below:
<dependency>
    <groupId>org.junit.platform</groupId>
    <artifactId>junit-platform-launcher</artifactId>
    <version>1.7.0</version>
    <scope>test</scope>
</dependency>
