Как перебрать зависимости проекта в Gradle

Question

Я определил простую задачу

task printCompileTestLib { 
     configurations.testCompile.each { println it } 
} 

test.dependsOn(printCompileTestLib) 

Но когда я выполнить задание следующих ошибок происходит:

FAILURE: Build failed with an exception. 

* Where: 
Build file 'D:\projects\fwk\trunk-gradle\ext\build.gradle' line: 2 

* What went wrong: 
A problem occurred evaluating project ':ext'. 
> You can't change a configuration which is not in unresolved state! 

* Try: 
Run with --debug option to get more log output. 

* Exception is: 
org.gradle.api.GradleScriptException: A problem occurred evaluating project ':ext'.

Вопрос заключается в том, как я могу перебирать зависимости проекта? Есть ли способ извлечь каждую группу зависимостей , модуль и версия в задаче?

Answer 1

Вам нужно перебирать зависимости в задаче выполнения времени, а не на задачах конфигурации время:

task printCompileTestLib { 
    // doLast adds a so-called task action, which will 
    // only get run if and when the task gets executed 
    doLast { 
     configurations.testCompile.each { println it } 
    } 
}
