How to execute task in Gradle?

Question

I have the following project structure:

• application
  • build.gradle
• build.gradle
• settings.gradle

application/build.gradle:

apply plugin: 'java'

settings.gradle:

include ':application'

build.gradle:

task custom << {
  project.tasks.getByName("build").execute()
}

So I want to execute task "build" inside task "custom". But when I run "gradle custom" the result is:

:custom FAILED

FAILURE: Build failed with an exception.

* Where:
Build file '/tmp/test/build.gradle' line: 3

* What went wrong:
Execution failed for task ':custom'.
> Task with name 'build' not found in root project 'test'.

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

BUILD FAILED

Total time: 1.183 secs

How I can execute the task "build" inside task "custom" ?

Answer 1

You cannot. Task execution is declarative, not imperative. Tasks depend on each other, they do not execute each other. (Also, since you don't apply the Java (base) plugin in the root build script, the root project doesn't have a build task.)
