An improper way to share build logic between subprojects is _cross-project configuration_ via the link:{javadocPath}//org/gradle/api/Project.html#subprojects-groovy.lang.Closure-[`subprojects {}`] and link:{javadocPath}/org/gradle/api/Project.html#allprojects-groovy.lang.Closure-[`allprojects {}`] DSL constructs.

TIP:  Avoid using `subprojects {}` and `allprojects {}`.

        "project(':').subprojects"               | "subprojects of project ':'"
        "project(':').subprojects.each"          | "subprojects of project ':'"
        "rootProject.subprojects"                | "subprojects of project ':'"
        "parent.subprojects"                     | "subprojects of project ':'"
        "project(':b').project(':').subprojects" | "subprojects of project ':'"

This is sometimes referred to as a multi-module project.
Gradle refers to modules as subprojects.

A multi-project build consists of one root project and one or more subprojects.

== Multi-Project structure

The following represents the structure of a multi-project build that contains two subprojects:

The directory structure should look as follows:

        def body = ""
        def isParent = subProjectNumber == null || config.subProjects == 0
        def hasSources = subProjectNumber != null || config.subProjects == 0
        if (isParent) {
            if (config.subProjects != 0) {
                body += """
                    <modules>
                        ${(0..config.subProjects - 1).collect { "<module>project$it</module>" }.join("\n                ")}

        settingsFile << """
            rootProject.name = 'root'
            include '1', '2'
        """
        buildFile << """
            subprojects {
                task otherBuild(type:GradleBuild) {
                    dir = "\${rootProject.file('subprojects')}"
                    tasks = ['log']
                    buildName = project.name + "nested"
                    def startEvent = project.name + "-started"

    def "will substitute and run build dependencies for closed projects on startup"() {
        setup:
        multiProjectBuildInRootFolder("parent", ["child1", "child2"]) {
            buildFile << """
            subprojects {
                apply plugin: 'java-library'
            }
            project(":child1") {
                configurations {
                    testArtifacts
                }

```
