开发笔记:直接在子项目中添加任务与从根项目添加“子项目”之间的区别

篇首语：本文由编程笔记#小编为大家整理，主要介绍了直接在子项目中添加任务与从根项目添加“子项目”之间的区别相关的知识，希望对你有一定的参考价值。

我有问题，在子项目中访问配置时获取空数组

我有一个gradle项目（gradle版本5.3.1），结构如下

在settings.gradle中

rootProject.name = 'Gradle-Test' include 'subproject1', 'subproject2'

在子项目的build.gradle文件中，仅定义依赖项，如下所示

repositories { mavenCentral() } dependencies { compile group: 'org.slf4j', name: 'slf4j-api', version: '1.7.26' }

由于我想获得子项目的依赖项，我在root项目的build.gradle中添加任务，如下所示

allprojects.each { p -> configure(p) { task showConfig { println p.name println p.configurations } } }

然而，当我运行./gradlew showConfig时，我得到了

我无法获得子项目的配置，它返回一个空数组

我希望得到如下结果

> Configure project : Gradle-Test [configuration ':annotationProcessor', configuration ':apiElements', configuration ':archives', configuration ':compile', configuration ':compileClasspath', configuration ':compileOnly', configuration ':default', configuration ':implementation', configuration ':runtime', configuration ':runtimeClasspath', configuration ':runtimeElements', configuration ':runtimeOnly', configuration ':testAnnotationProcessor', configuration ':testCompile', configuration ':testCompileClasspath', configuration ':testCompileOnly', configuration ':testImplementation', configuration ':testRuntime', configuration ':testRuntimeClasspath', configuration ':testRuntimeOnly'] > Configure project :subproject1 subproject1 [configuration ':subproject1:annotationProcessor', configuration ':subproject1:apiElements', configuration ':subproject1:archives', configuration ':subproject1:compile', configuration ':subproject1:compileClasspath', configuration ':subproject1:compileOnly', configuration ':subproject1:default', configuration ':subproject1:implementation', configuration ':subproject1:runtime', configuration ':subproject1:runtimeClasspath', configuration ':subproject1:runtimeElements', configuration ':subproject1:runtimeOnly', configuration ':subproject1:testAnnotationProcessor', configuration ':subproject1:testCompile', configuration ':subproject1:testCompileClasspath', configuration ':subproject1:testCompileOnly', configuration ':subproject1:testImplementation', configuration ':subproject1:testRuntime', configuration ':subproject1:testRuntimeClasspath', configuration ':subproject1:testRuntimeOnly'] > Configure project :subproject2 subproject2 [configuration ':subproject2:annotationProcessor', configuration ':subproject2:apiElements', configuration ':subproject2:archives', configuration ':subproject2:compile', configuration ':subproject2:compileClasspath', configuration ':subproject2:compileOnly', configuration ':subproject2:default', configuration ':subproject2:implementation', configuration ':subproject2:runtime', configuration ':subproject2:runtimeClasspath', configuration ':subproject2:runtimeElements', configuration ':subproject2:runtimeOnly', configuration ':subproject2:testAnnotationProcessor', configuration ':subproject2:testCompile', configuration ':subproject2:testCompileClasspath', configuration ':subproject2:testCompileOnly', configuration ':subproject2:testImplementation', configuration ':subproject2:testRuntime', configuration ':subproject2:testRuntimeClasspath', configuration ':subproject2:testRuntimeOnly'] BUILD SUCCESSFUL in 0s

，通过在每个build.gradle中添加以下任务

task showConfig { println project.name println project.configurations }

谁能告诉我在我的gradle中出了什么问题？

你把你的println放在了错误的地方。它们在配置阶段而不是执行阶段触发。
