Hi,

I’m moving tasks from build.gradle into their respective groovy class definitions that extend from the DefaultTask so I can then reference these tasks in my custom plugin.

My question is how do I indicate that one task depends on another? In build.gradle I used “dependsOn” clause, but how do I specify it in my custom task groovy class implementation?

Thanks, Dmitriy.

You don’t. Task dependencies are declared by the party (build script or plugin) declaring the task instance, not by the party implementing the task type.
