You should read documentation, really - Allure reports + TestNG and run from command line.

 One have to read documentation, no options! It clearly stated that you have to run java process in a special way if you want to get steps, attachments etc info in your Allure report upon running a TestNG based test set.  And no, I had to spend two hours just to re-read the spec and discover that aspectjweaver dependency! And only after that it became clear that here is the way:

aspectjweaver_jar_file_name="$(ls ./lib/aspectjweaver-*.jar | xargs echo)"
java -ea -javaagent:"$aspectjweaver_jar_file_name" -cp "${full_classpath}" org.testng.TestNG ./test_suites/$testXmlName
