如何向 Gradle 添加新的源集？

2021年最新情况:

八年来发生了很多变化。分级仍然是一个伟大的工具。现在，文档中有一个完整的部分专门用于配置集成测试。我现在向你推荐 看看文件。

原答案:

我花了一段时间才弄明白，而且网上的资源也不是很好。所以我想记录我的解决方案。

这是一个简单的 gradle 构建脚本，除了主源代码集和测试源代码集之外，还有一个 intTest 源代码集:

apply plugin: "java"


sourceSets {
// Note that just declaring this sourceset creates two configurations.
intTest {
java {
compileClasspath += main.output
runtimeClasspath += main.output
}
}
}


configurations {
intTestCompile.extendsFrom testCompile
intTestRuntime.extendsFrom testRuntime
}


task intTest(type:Test){
description = "Run integration tests (located in src/intTest/...)."
testClassesDir = project.sourceSets.intTest.output.classesDir
classpath = project.sourceSets.intTest.runtimeClasspath
}

下面是我如何在不使用 configurations{ }的情况下做到这一点的。

apply plugin: 'java'


sourceCompatibility = JavaVersion.VERSION_1_6


sourceSets {
integrationTest {
java {
srcDir 'src/integrationtest/java'
}
resources {
srcDir 'src/integrationtest/resources'
}
compileClasspath += sourceSets.main.runtimeClasspath
}
}


task integrationTest(type: Test) {
description = "Runs Integration Tests"
testClassesDir = sourceSets.integrationTest.output.classesDir
classpath += sourceSets.integrationTest.runtimeClasspath
}

使用: Gradle 1.4和 Gradle 1.6进行测试

This was 2016年曾经为2.x/3.x 年级写过，现在已经过时了!! Please have a look at the documented solutions in Gradle 4 and up

To sum up both old answers (get best and minimum viable of both worlds):

一些温暖的话首先:

1. 首先，我们需要定义 sourceSet:

   sourceSets {
   integrationTest
   }
   

2. next we expand the sourceSet from test, therefor we use the test.runtimeClasspath (which includes all dependenciess from test AND test itself) as classpath for the derived sourceSet:

   sourceSets {
   integrationTest {
   compileClasspath += sourceSets.test.runtimeClasspath
   runtimeClasspath += sourceSets.test.runtimeClasspath // ***)
   }
   }
   

   • 不知怎么的，这个 sourceSets.integrationTest.runtimeClasspath的重新声明/扩展是必需的，但是应该是不相关的，因为 runtimeClasspath总是扩展 output + runtimeSourceSet，不要得到它

3. 我们为运行集成测试定义了一个专门的任务:

   task integrationTest(type: Test) {
   }
   

4. Configure the integrationTest test classes and classpaths use. The defaults from the java plugin use the test sourceSet

   task integrationTest(type: Test) {
   testClassesDir = sourceSets.integrationTest.output.classesDir
   classpath = sourceSets.integrationTest.runtimeClasspath
   }
   

5. (optional) auto run after test

   integrationTest.dependsOn test
   

6. (optional) add dependency from check (so it always runs when build or check are executed)

   tasks.check.dependsOn(tasks.integrationTest)
   

7. (optional) add java,resources to the sourceSet to support auto-detection and create these "partials" in your IDE. i.e. IntelliJ IDEA will auto create sourceSet directories java and resources for each set if it doesn't exist:

   sourceSets {
   integrationTest {
   java
   resources
   }
   }
   

apply plugin: 'java'


// apply the runtimeClasspath from "test" sourceSet to the new one
// to include any needed assets: test, main, test-dependencies and main-dependencies
sourceSets {
integrationTest {
// not necessary but nice for IDEa's
java
resources


compileClasspath += sourceSets.test.runtimeClasspath
// somehow this redeclaration is needed, but should be irrelevant
// since runtimeClasspath always expands compileClasspath
runtimeClasspath += sourceSets.test.runtimeClasspath
}
}


// define custom test task for running integration tests
task integrationTest(type: Test) {
testClassesDir = sourceSets.integrationTest.output.classesDir
classpath = sourceSets.integrationTest.runtimeClasspath
}
tasks.integrationTest.dependsOn(tasks.test)
