Android 项目进行了模块化，手工运行完测试用例之后，jacoco 只统计一个模块下面的代码覆盖，其它模块的统计出来的数据都是为 0。

build.gradle：

apply plugin: "jacoco"

def coverageSourceDirs = ['../app/src/']

task jacocoTestReport(type: JacocoReport) {

group = "Reporting"

description = "Generate Jacoco coverage reports after running tests."

reports {

xml.enabled true

html.enabled true

}

classDirectories = fileTree(

dir: './build/intermediates/classes/product/debug',

excludes: ['/R*.class',

'/$InjectAdapter.class',

'/$ModuleAdapter.class',

'*/$ViewInjector*.class'

])

sourceDirectories = files(coverageSourceDirs)

executionData = files("$buildDir/outputs/code-coverage/connected/coverage.ec")

doFirst {

new File("$buildDir/intermediates/classes/").eachFileRecurse { file ->

if (file.name.contains('$$')) {

file.renameTo(file.path.replace('$$', '$'))

}

}

}

}

统计代码如下：

OnCreate：

String SDCARD_PATH = Environment.getExternalStorageDirectory().getPath();

String DEFAULT_COVERAGE_FILE_PATH = SDCARD_PATH + "/coverage.ec";

File file = new File(DEFAULT_COVERAGE_FILE_PATH);

if (! file.exists()) {

try {

file.createNewFile();

} catch (IOException e) {

e.printStackTrace();

}

}

OnDestroy：

public void generateCoverageReport() {

String SDCARD_PATH = Environment.getExternalStorageDirectory().getPath();

String DEFAULT_COVERAGE_FILE_PATH = SDCARD_PATH + "/coverage.ec";

Log.d("generateCoverageReport", "generateCoverageReport():" + DEFAULT_COVERAGE_FILE_PATH);

OutputStream out = null;

try {

out = new FileOutputStream(DEFAULT_COVERAGE_FILE_PATH, false);

Object agent = Class.forName("org.jacoco.agent.rt.RT").getMethod("getAgent").invoke(null);

out.write((byte[]) agent.getClass().getMethod("getExecutionData", boolean.class).invoke(agent, false));

} catch (Exception e) {

Log.d("generateCoverageReport", e.toString(), e);

} finally {

if (out != null) {

try {

out.close();

} catch (IOException e) {

e.printStackTrace();

}

}

}

}

覆盖数据都有，只是 HTML 文件显示代码都未运行，可以确认 MainActivity 是有运行的，但并未统计出来。求大神解答
