In order to configure the file name of the generated report (which is "surefire-report" by default), the outputName property should be set to the desired name.
<project> [...] <reporting> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-surefire-report-plugin</artifactId> <version>3.0.0-M1</version> <configuration> <outputName>desired_name</outputName> </configuration> </plugin> </plugins> </reporting> [...] </project>
And after executing mvn site, the generated report file is named desired_name.html.
