What is the correct way to run clean and build on all module kotlinlang #gradle

What is the correct way to run 'clean' and 'build' on all modules within a project? If I click 'clean' from the Gradle window on the root of the project, it will perform the task correctly, but if I put

dependsOn("clean")

in my script, it will only execute for one of the modules.

Some other semi-related questions because I can't find information about this anywhere: is it considered good practice to run things like 'build' and 'clean' on multiple modules from within a task? And one other question: what is the best method of running things one after another in a precompiled script? I just have a list of `dependsOn()`s right now and it's causing issues.

For reference, I am making a task that will clean my project, rebuild, locate the new artifacts, and then deploy them to our Sonatype repo. I have no idea if putting that all into a single task (using

dependsOn()

for cleaning and building, then manually locating the artifacts within their respective

lib

folders) is the proper way to do this.

dependsOn("clean")
in my script, it will only execute for one of the modules.

Running

./gradlew clean

triggers all tasks with the same name in all modules - you can check it with

./gradlew -m clean

. Using

dependsOn("clean")

adds dependency only to one particular module

"clean"

task.

@tapchicoma I see. So the only way to clean multiple modules within a script is to run them all individually?

slightly different task goal, but will give you a direction:

task cleanCache(type: Delete) {
    description "Clean all local build caches (Gradle and Android)"
    group "Build"
    dependsOn allprojects.collect { subproject ->
        subproject.tasks.matching {
            it.name == 'cleanBuildCache'
        }
    }
    delete gradle.ext.buildCacheDir
}
