net.masterthought.cucumber.ValidationException: No report file was added - cucumber-jvm

Question

Report is not getting generated When i am using cucumber-maven reporting plugin see image here

Answer 1

Primary Thing: Message "net.masterthought.cucumber.ValidationException: No report file was added!" generally comes when there is something wrong in the configuration of Maven Cucumber Html Report Plugin. (configuration example below)
<plugin>
<groupId>net.masterthought</groupId>
<artifactId>maven-cucumber-reporting</artifactId>
<version>4.2.3</version>
<executions>
<execution>
<id>execution</id>
<phase>verify</phase>
<goals>
<goal>generate</goal>
</goals>
<configuration>
<projectName>TheDayAfterTomorrow</projectName>
<!-- output directory for the generated report -->
<outputDirectory>${project.build.directory}/cucumber-maven-report</outputDirectory>
<inputDirectory>${project.build.directory}/cucumber-json</inputDirectory>
<jsonFiles>
<!-- supports wildcard or name pattern -->
<param>**/*.json</param>
</jsonFiles>
<skippedFails>true</skippedFails>
<enableFlashCharts>true</enableFlashCharts>
<buildNumber>10.2.1</buildNumber>
<parallelTesting>false</parallelTesting>
</configuration>
</execution>
</executions>
</plugin>
Secondary Thing, in case you are still using old version of cucumber (1.2.5) so update your POM file with latest available cucumber version or anything above >=4.0.0 in order to have better outcome.
Cucumber Execution via JUnit:
<dependency>
<groupId>io.cucumber</groupId>
<artifactId>cucumber-junit</artifactId>
<version>4.2.6</version>
</dependency>
<dependency>
<groupId>io.cucumber</groupId>
<artifactId>cucumber-picocontainer</artifactId>
<version>4.2.6</version>
</dependency>
Cucumber Execution via TestNG:
<dependency>
<groupId>io.cucumber</groupId>
<artifactId>cucumber-picocontainer</artifactId>
<version>4.2.6</version>
</dependency>
<dependency>
<groupId>io.cucumber</groupId>
<artifactId>cucumber-testng</artifactId>
<version>4.2.6</version>
</dependency>

Answer 2

The root cause of this issue is that maven-cucumber-reporting can't find any JSON file in the directory that was defined in the POM. This JSON file is generated using #CucumberOptions annotation in the runner class. So the problem that you see is because you have defined a different directory in #CucumberOptions and in the inputDirectory field within the configuration of the plugin in the POM file.
To solve it, make sure that both directories match. For example:
In the runner file you should have target/cucumber/cucumber.json
#CucumberOptions(features = "classpath:feature", tags = "#component-test",
glue = {"feature.component"},
plugin = {"json:target/cucumber/cucumber.json")
So in the POM you should have <inputDirectory>${project.build.directory}/cucumber</inputDirectory> and you should make sure that jsonFiles property is correctly defined:
<jsonFiles>
<param>**/*.json</param>
</jsonFiles>
So at the end the configuration should look like:
<plugin>
<groupId>net.masterthought</groupId>
<artifactId>maven-cucumber-reporting</artifactId>
<version>${maven-cucumber-reporting.version}</version>
<executions>
<execution>
<id>generate-cucumber-reports</id>
<phase>test</phase>
<goals>
<goal>generate</goal>
</goals>
<configuration>
<jsonFiles>
<param>**/*.json</param>
</jsonFiles>
<outputDirectory>${project.build.directory}/cucumber-reports</outputDirectory>
<inputDirectory>${project.build.directory}/cucumber</inputDirectory>
<checkBuildResult>false</checkBuildResult>
</configuration>
</execution>
</executions>
</plugin>
