계측 클래스의 계단 오류

Question

Jacoco의 POC 및 GigaProject 용 gradle에 대해 작업 중이며 "테스트"작업 인 aka 계측 테스트 소스 코드 중에 jacoco에 도착하면이 오류가 발생합니다. 어떤 아이디어? 감사.

Answer 1

좋습니다. Gradle build.gradle 파일에서 다음과 같은 테스트 {...} 섹션을 사용했으며 classDumpPath 설정 (내 끝 부분에 맞춤 폴더 설정)을 사용하고있었습니다.

test { 
    maxParallelForks = 5 
    forkEvery = 50 
    ignoreFailures = true 

    testReportDir = file("$buildDir/reports/tests/UT") 
    testResultsDir = file("$buildDir/test-results/UT") 


    //Following Jacoco test section is required only in Jenkins instance extra common file 
    jacoco { 
     //The following vars works ONLY with 1.6 of Gradle 
     destPath = file("$buildDir/jacoco/UT/jacocoUT.exec") 
     classDumpPath = file("$buildDir/jacoco/UT/classpathdumps") 

     //Following vars works only with versions >= 1.7 version of Gradle 
     //destinationFile = file("$buildDir/jacoco/UT/jacocoUT.exec") 
     // classDumpFile = file("$buildDir/jacoco/UT/classpathdumps") 
    } 
    } 

다음 줄에 주석을 달았습니다. 나중에 문제를 해결하는 이유는 나중에 살펴 보겠습니다.

//--- classDumpPath = file("$buildDir/jacoco/UT/classpathdumps")
