Project.getTasksByName() causes StackOverflow

[xtracoder]

I think there is something wrong with implementation of project.getTasksByName() and similar staff
(currently running with Gradle 2.10)

Please check the Use-Case #1 in this thread

Gradle 2.9: "Unexpected afterEvaluate event received without beforeEvaluate"

I’m receiving %SUBJ% message in the environment as described here This seems to be internal bug. After commenting/un-commenting my build scripts line by line I’ve traced that presense of ‘project.getTasksByName’ within '‘gradle.beforeProject()’ causes recursive re-evaluation of the same project - and that follows either to StackOverflow or to above mentioned exception. Steps to reproduce: minimal project structure root p1 - empty build.gradle p2 - empty build.gradle in the root fol…

Recently I’ve got into similar use-case in (significantly truncated) code like following:

afterProject { project ->
        try {
            println 'do find by name: ' + project + ' ? ' + debuggedTaskName
            task = project.tasks.findByName(debuggedTaskName)
            println '  ... -> ' + task

            println 'do find by path: ' + project.rootProject + ' ? ' + debuggedTaskName
            task = project.rootProject.tasks.findByPath(debuggedTaskName)
            println '  ... -> ' + task

            println 'done'
        }
        catch( Exception e ) {
            e.printStackTrace()
        }
    }
}

the output is below and it looks like something gets executed twice - in the output below i see that call to project.rootProject.tasks.findByPath() triggers recursive evaluation of ‘afterProject’ what fails when returning back to 1st level of ‘afterProject’

Configuration on demand is an incubating feature.
do find by name: root project 'root-project' ? :sub-project:run
  ... -> null
do find by path: root project 'root-project' ? :sub-project:run
do find by name: project ':sub-project' ? :sub-project:run
  ... -> null
do find by path: root project 'root-project' ? :sub-project:run
  ... -> task ':sub-project:run'
done
