Executing test com.linkedin.dynamometer.TestDynamometerInfra stuck

I try to build latest dynamometer
When it run TestDynamometerInfra, it seems it stuck at this point
Dose anything need to be pre-installed for the build

kevin@kevin-pc:~/git/dynamometer(master)$ ./gradlew build

Start by running ./gradlew build and inspect the dynamometer-infra:test task, especially com.linkedin.dynamometer.TestDynamometerInfra, where the report says execution stops after two tests. Compare the test output and configuration to determine whether the test is genuinely stuck or waiting on a required environment dependency; done means the test completes and the build reports a clear result.
