如何在Gradle子项目中指定配置顺序？

Question

settings.gradle是：

rootProject.name = 'snth'

include 'snth-proto-definition'
include 'snth-server'
include 'snth-client-guice'

snth-server/build.gradle有：

sourceSets {
  main {
    java {
      srcDir "${project(':snth-proto-definition').protobuf.generatedFilesBaseDir}/server/java"
    }
  }
}

snth-client/build.gradle有：

sourceSets {
  main {
    java {
      srcDir "${project(':snth-proto-definition').protobuf.generatedFilesBaseDir}/client/java"
    }
  }
}

但是，snth-server-guice/build.gradle处理正常，snth-client-guice/build.gradle错误：

FAILURE: Build failed with an exception.

* Where:
Build file 'snth/snth-client-guice/build.gradle' line: 14

* What went wrong:
A problem occurred evaluating project ':snth-client-guice'.
> Could not find property 'protobuf' on project ':snth-proto-definition'.

如何确保project(':snth-proto-definition').protobuf在使用之前已定义？

Answer 1

Configuration time dependencies表示使用evaluationDependsOn可以更精细地控制子模块的配置顺序。例如：

evaluationDependsOn(':snth-proto-definition')
