How to generate Cucumber extent reports 4 through Gradle

Question

I am executing the Cucumber automation test scripts through gradle, though i am able to execute the test successfully but reports are not getting generated. I did give a try with with below gradle tasks one at a time.

Cucumber gradle tasks copied below

a) for the below gradle task i am able to execute the scripts which does not generate reports as i have not included the reports statements inside args

task cucumber() {
    dependsOn assemble, testClasses
    doLast {
        javaexec {
            main = "io.cucumber.core.cli.Main"
            classpath = configurations.cucumberRuntime + sourceSets.main.output + sourceSets.test.output
            
            args = ['--plugin', 'pretty', 
                  
                    '--glue','com.hal.brands.test.stepdefinition',
                    
                    'src/test/resources','src/main/java',

                    '--tags', '@Api'        
                    ]
           
               }
       
        }
    }

b) I tried to include the few statements related to reporting as shown in below gradle task but it failed with a exception

    task cucumber() {
        dependsOn assemble, testClasses
        doLast {
            javaexec {
                main = "io.cucumber.core.cli.Main"
                classpath = configurations.cucumberRuntime + sourceSets.main.output + sourceSets.test.output
                
                args = ['--plugin', 'pretty', 'json:target/HalBrands.json', 'com.aventstack.extentreports.cucumber.adapter.ExtentCucumberAdapter:',
                
                        '--monochrome', 'true',
                
                        '--features','src\test\resources\featurefile',
                
                        '--glue','com.hal.brands.test.stepdefinition',
                        
                        'src/test/resources','src/main/java', 
    
                        '--tags', '@Api'         
                        ]
              
            }
           
        }
      }

I am not sure where i am going wrong in the above 'b' gradle task . Please help with me at the earliest as iam literally wasting lot of time here trying out many possibilities. Also i want to keep you informed that i am new gradle stuff.

Have also copied cucumberoptions as present in my cucumber runner file

@CucumberOptions(features = { "classpath:featurefile" }, glue = { "classpath:com.hal.brands.test.stepdefinition",
            "classpath:com.hal.brands.helper" }, 
            
            plugin = { "pretty", "json:target/HalBrands.json", "com.aventstack.extentreports.cucumber.adapter.ExtentCucumberAdapter:" },
    
            monochrome = true, tags = "@Api")

Answer 1

Pls take off the json: to get rid of the exception you are getting wrt to invalid scheme!
