When a buildSrc directory exists, Android Studio will erroneously show Method 'doLast' is not implemented errors on custom tasks:
To verify the issue I create a new empty Android project in Android Studio (I use V 3.0.1) add a simple custom task to the root build.gradle file
class Greeting extends DefaultTask {
String message
String recipient
@TaskAction
void sayGreeting() {
println "gradle version ${project.getGradle().getGradleVersion()}"
println "${message}, ${recipient}!"
}
}
task hello (type : Greeting) {
group 'Welcome'
description 'Produces a world greeting'
message 'Hello'
recipient 'World'
}
This is a very simple example from the gradle-guide Writing Gradle Tasks.
The default project uses my gradle V4.1 installation.
When I now refresh the Gradle projects, I can execute the hello task and the IDE shows no errors in the build.gradle file.
But when you now add a buildSrc dir to the project (can be empty) and refresh the Gradle projects again, Android Studio 3.0.1 shows this error: Method 'doLast' is not implemented
Any ideas what's going on and how to fix this (without implementing the missing methods)?
