Answer 1

Step 1. Add dependencies Allure Builder Reporter into pom.xml https://mvnrepository.com/artifact/ru.yandex.qatools.allure/allure-report-builder/2.1

Step 2: Added below code.

// It will generate the Allure Report folder.
new AllureReportBuilder("1.5.4", new File("target/allure-report")).unpackFace(); 
new AllureReportBuilder("1.5.4", new File("target/allure-report")).processResults(new File("target/allure-results"));

Answer 2

Update your allure command-line to version 2

Explanation:

Allure work in 2 step.

• First step, during the execution of your tests, generate data files.
• Second step, after the execution of your tests, generate your web report.
• In allure version 1. Data files are in XML.
• In allure version 2. Data files are in JSON.

So when you trigger in your command line with allure (version 1). He looks for XML files. Since your files are in JSON, he don't find any data and generate an empty report.

---

To check your version of allure command-line:

allure --version

Ensure you have the version 2.x.x
