設定Jenkins全域變數
Manage Jenkins -> Configure System -> Global properties ->  Environment variables 打勾 並且 add

androidTest :跑在機器上 or 模擬器上

test:跑上jvm上，純java unit test

build.gradle(Module:app):新增依賴

apply plugin: 'jacoco'

task jacocoAndroidTestReport(type:JacocoReport,dependsOn:"connectedAndroidTest"){
    group = "Reporting"
    description = "Generate Jacoco coverage reports after running tests."

//jacocoTestReport依賴於test task，所以在執行jacoco之前需要先執行test
