This happens sometime between the completion of the last task that uses the build service and the end of the build.

Here is an example of a service that takes parameters and is closeable:

====
[source.multi-language-sample,java]
.WebServer.java
----
include::{snippetsPath}/plugins/buildService/groovy/buildSrc/src/main/java/WebServer.java[]
----
====

    }

    def "can add dir to multi set"() {
        def parent = tmpDir.createDir()
        def dir1 = parent.createDir("dir1")
        def dir2 = parent.createDir("dir2")
        def dir3 = parent.createDir("dir3")
        def other = parent.createDir("dir4")
        def child = dir1.createDir("child1")
        def multi = from(dir1, dir2)

        expect:
        def s1 = multi.plus(dir3)

        Long millis;

        millis = params.get("delayMillisAfterProcessing");
        if (millis != null) {
            delayMillisAfterProcessing = millis;
        }

        millis = params.get("delayMillisAtNoUrlInQueue");
        if (millis != null) {
            delayMillisAtNoUrlInQueue = millis;
        }

        millis = params.get("delayMillisBeforeProcessing");
