Add properties to project in Gradle plugin

Question

I'm trying to add some properties to a project, which is configured with custom plugin.

class MyPlugin implements Plugin<Project> {
    @Override
    void apply(Project project) {
        project.properties.put("my_property", "123)
        println(project.properties.get("my_property"))
    }
}

I see null in output. What I am missing here?

Answer 1

Here's how extra properties should be set:

class MyPlugin implements Plugin<Project> {
    @Override
    void apply(Project project) {
        project.ext.my_property = 123
        println(project.my_property)
    }
}
