[[part4_begin]]
== Step 0. Before you Begin

1. You initialized your Java app in <<partr1_gradle_init.adoc#part1_begin,part 1>>.
2. You understand the Gradle Build Lifecycle from <<partr2_build_lifecycle.adoc#part2_begin,part 2>>.
3. You added a subproject and a separate Build in <<partr3_multi_project_builds#part3_begin, part3>>.

== Step 1. Gradle scripts

Build scripts and setting files are code.
They are written in Kotlin or Groovy.

3. You added a subproject and a separate Build in <<partr3_multi_project_builds#part3_begin, part3>>.
4. You viewed a Settings file in <<partr4_settings_file.adoc#part4_begin,part 4>>.
5. You authored a Build script in <<partr5_build_scripts.adoc#part5_begin,part 5>>.
6. You authored a Task in <<partr6_writing_tasks.adoc#part6_begin,part 6>>.

== Step 1. Develop the Plugin

        }

        public BeanWithMultiArgDslMethods prop(String part1, String part2) {
            this.prop = String.format("<%s%s>", part1, part2);
            return this;
        }
        public BeanWithMultiArgDslMethods prop(String part1, String part2, String part3) {
            this.prop = String.format("[%s%s%s]", part1, part2, part3);
            return this;
        }
    }

3. You added a subproject and a separate Build in <<partr3_multi_project_builds#part3_begin, part3>>.
4. You viewed a Settings file in <<partr4_settings_file.adoc#part4_begin,part 4>>.
5. You authored a Build script in <<partr5_build_scripts.adoc#part5_begin,part 5>>.

== Step 1. Understand Tasks
A Task is an executable piece of code that contains sequences of actions.

		buf.String(), "body of part 3")

	// Part4
	part, err = reader.NextPart()
	if part == nil || err != nil {
		t.Error("Expected part 4 without errors")
		return
	}

	// Non-existent part5
	part, err = reader.NextPart()
	if part != nil {
		t.Error("Didn't expect a fifth part.")
	}
	if err != io.EOF {
		t.Errorf("On fifth part expected io.EOF; got %v", err)
	}
}
