问题

在我的Gradle构建中，我有两个类似这样的测试任务：

```groovy
task testAAA(type: Test) {
    filter {
        includeTestsMatching "*AAA*"
    }
    finalizedBy jacocoTestReport
}

以及

task testBBB(type: Test) {
    filter {
        includeTestsMatching "*BBB*"
    }
    finalizedBy jacocoTestReport
}

这将在build/jacoco目录中生成两个.exec文件：

• testAAA.exec
• testBBB.exec

我希望生成一个汇总的覆盖率报告，该报告从所有.exec文件中获取输入。我尝试了以下方式：

jacocoTestReport {
    executionData fileTree(project.rootDir.absolutePath).include("**/build/jacoco/*.exec")
    reports {
        xml.enabled true
    }
}

但是当我尝试时，我得到了以下错误：

Execution failed for task ':Project1:jacocoTestReport'.
> Unable to read execution data file Project1/build/jacoco/test.exec
Project1/build/jacoco/test.exec (No such file or directory)

为什么jacocoTestReport在明确提供了executionData规范时还会寻找"test.exec"文件呢？

<summary>英文:</summary>

In my gradle build I have 2 test tasks like this:

task testAAA(type: Test) {
filter {

    includeTestsMatching "*AAA*"
}

finalizedBy jacocoTestReport

}

and

task testBBB(type: Test) {
filter {

    includeTestsMatching "*BBB*"
}

finalizedBy jacocoTestReport

}

This generates 2 .exec files in build/jacoco:

 - testAAA.exec

 - testBBB.exec

I want to generate a single coverage report that takes input from BOTH/ALL of the .exec files, I tried this:

jacocoTestReport {
executionData fileTree(project.rootDir.absolutePath).include("**/build/jacoco/*.exec")

reports {
    xml.enabled true
}

}

When I try that I get this error:

Execution failed for task ':Project1:jacocoTestReport'.
> Unable to read execution data file Project1/build/jacoco/test.exec

Project1/build/jacoco/test.exec (No such file or directory)

Why is jacocoTestReport looking for "test.exec" when I explicitly provided an executionData specification?

我曾经为此苦苦挣扎，甚至取得了一些成功。直到昨天我回头再次处理它。花了几个小时的时间进行搜索，发现了在 GH 上的这个解决方法。

    jacocoTestReport {
      getExecutionData().setFrom(fileTree(buildDir).include("/jacoco/*.exec")) 
    }

自 Gradle 6.0 起，这就是要走的路。我已经在一个包含两套测试的存储库上进行了测试，我可以分别运行它们，也可以同时运行两套测试，而 Jacoco 不会出问题。

我建议传入测试任务而不是文件树。这将允许插件确保正确查找文件，并解决一些可能出现的执行顺序问题，比如确保此报告任务在测试任务本身之后运行。

所以可以像这样：

jacocoTestReport {
    executionData tasks.withType(Test)

    reports {
        xml.enabled true
    }
}

jacocoTestReport {
    executionData tasks.withType(Test)

    reports {
        xml.enabled true
    }
}

以下是翻译好的内容：

"jacocoTestReport"任务是预定义的 JacocoReport 任务，它默认会设置一个执行数据文件，文件名为 "test.exec"。

因此，你可以尝试以下代码：

task testAAAReport(type: JacocoReport) {
    sourceSets sourceSets.main

    executionData fileTree(project.rootDir.absolutePath).include("**/build/jacoco/*.exec")

    reports {
        xml.enabled true
    }

}

task testAAAReport(type: JacocoReport) {
    sourceSets sourceSets.main

    executionData fileTree(project.rootDir.absolutePath).include("**/build/jacoco/*.exec")

    reports {
        xml.enabled true
    }

}
