如何在Gradle中执行任务？

Question

我有以下项目结构:

• 应用
  • 的build.gradle
• 的build.gradle
• settings.gradle

应用/的build.gradle:

apply plugin: 'java'

settings.gradle:

include ':application'

的build.gradle:

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

所以我想在任务"custom"中执行任务"build".但是当我运行"gradle custom"时,结果是:

: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

我如何在"自定义"任务中执行"构建"任务？

Answer 1

你不能.任务执行是声明性的,而不是命令式的.任务彼此依赖,它们不会相互执行.(另外,由于您没有在根构建脚本中应用Java(基础)插件,因此根项目没有build任务.)
