Print the environment map for Gradle test task

Question

With Java plugin test task in Gradle, how can I print the environment map for the JVM process which executes the tests.

test.doFirst {
        environment 'KAFKA_PORT', "${KAFKA_TCP_9902}"
        environment 'DB_PORT', "${MYSQL_TCP_3306}"
        // How to print the map of all environments set so far?
}

You can access the environment map directly. Just loop through it and print the values over the keys:

test.doFirst {
    [...] // do something
    environment.each { k, v -> println "${k}:${v}" }
}

Both the map property and two methods to add values, one of them you use, are named environment. By default, the environment variables from the Gradle process are used.
