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 tojunit-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>
