Gradle: Run subproject task also on dependency projects

I am stuck on the following Problem: I have a main project with multiple sub-projects, each dependent on each other. For example:

+---Main
    +- Shared
       +- Variant1
          +- Variant1A

If I run the build task on project 3 with the Variant1A:build command, all other projects get built too.

I now added a deploy task to every sub-project, and if I deploy one of my projects, I want to deploy every project it depends upon as well, like so:

+---Main:deploy
    +- Shared:deploy
       +- Variant1:deploy
          +- Variant1A:deploy

However running Variant1A:deploy only runs the task for the Variant1A project:

+---Main:build
    +- Shared:build
       +- Variant1:build
          +- Variant1A:deploy

As I have a lot of subprojects and many complicated dependencies, I don't want to specify each project with dependsOn.
So I am searching for a way to run the task on all local projects like build does, however I don't want to add the logic to the build task, as it should not be deployed in the normal building process...

from your root project's build.gradle you might be able to do something like this

// look for deploy as a task argument sent via command line
def isDeploy
// could be many tasks supplied via command line
for (def taskExecutionRequest : gradle.startParameter.taskRequests) {
    // we only want to make sure deploy was specified as a task request
    if (taskExecutionRequest.args.contains('deploy')) {
        isDeploy = true
    }
}
// if deploy task was specified then setup dependant tasks
if (isDeploy) {
    // add the task to all subprojects of the `rootProject`
    subprojects.each {
        // get all projects that depend on this subproject
        def projectDependencies = project.configurations.runtime.getAllDependencies().withType(ProjectDependency)
        // the subproject's dependant projects may also have project dependencies
        def dependentProjects = projectDependencies*.dependencyProject
        // now we have a list of all dependency projects of this subproject
        // start setting up the dependsOn task logic
        dependentProjects.each {
            // find the deploy task then make our dependant
            // project's deploy task a dependant of the deploy task
            tasks.findByName('deploy').dependsOn project(it.name).tasks.findByName('deploy')
        }
    }
}
