Run clean task before every build automatically in Gradle

Question

I want to run a project "clean" before the assembleRelease task in Gradle.

How can I trigger the clean task basically before everything?

In gradle you can use the dependsOn method.

B.dependsOn A

In this way:

task B depends on task A
gradle executes A task everytime before the B task execution.

In your case:

assembleRelease.dependsOn clean

the buildscript – xeruf Aug 02 '18 at 10:34
@Xerus Which one and where? `Could not get unknown property 'assembleRelease' for project ':app' of type org.gradle.api.Project.` – Bowi Apr 04 '19 at 16:15
It needs to be within the `tasks { }` block. Which buildscript depends on which project you want to configure. – xeruf Apr 05 '19 at 11:33

Adding to this, what I needed to do was have this in the

    android {
    afterEvaluate { 
       assemble(*your task here*)debug clean
}

and now it works great

Use following code to execute the clean task first per each build variant

project.afterEvaluate {
    android.applicationVariants.all { variant ->
        variant.outputs.each { output ->
            def capitalizedVariant = variant.name.capitalize()
            def assembleVariantTask = project.tasks."assemble${capitalizedVariant}"
            assembleVariantTask.dependsOn clean
        }
    }
}
