启用覆盖时，为什么Android Instrumentation测试报告失败？

Question

我正在尝试生成jacoco报告，但当我将testCoverageEnabled属性设置为true时，我不断收到错误消息。

java.lang.NoSuchMethodError: No static method $jacocoInit()[Z in class L... 

卸下testCoverageEnabled财产我可以运行测试，但我不能生成报告。

我使用标准的Jacoco配置。单独运行时单元测试和集成测试运行正常。

对此问题的所有在线引用似乎都是项目中的特定配置问题。任何帮助表示赞赏。

更新

apply plugin: 'jacoco' 

task jacocoTestReport(type: JacocoReport, dependsOn: ['testDebugUnitTest', 'createDebugCoverageReport']) { 

    reports { 
     xml.enabled = true 
     html.enabled = true 
    } 

    def fileFilter = ['**/R.class', '**/R$*.class', '**/BuildConfig.*', '**/Manifest*.*', '**/*Test*.*', 'android/**/*.*'] 
    def debugTree = fileTree(dir: "${buildDir}/intermediates/classes/debug", excludes: fileFilter) 
    def mainSrc = "${project.projectDir}/src/main/java" 

    sourceDirectories = files([mainSrc]) 
    classDirectories = files([debugTree]) 
    executionData = fileTree(dir: "$buildDir", includes: [ 
      "jacoco/testDebugUnitTest.exec", 
      "outputs/code-coverage/connected/*coverage.ec" 
    ]) 
}

我的工作配置。可能它可以帮助你。

apply plugin: 'jacoco' 

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

     jacoco { 
      toolVersion = "0.7.6.+" 
     } 

     task jacocoTestReport(type: JacocoReport, dependsOn: "testDebugUnitTest") { 
      group = "Reporting" 
      description = "Generate Jacoco coverage reports" 

      classDirectories = fileTree(
        dir: '../app/build/intermediates/classes', 
        excludes: ['**/R.class', 
           '**/R$*.class', 
           '**/*$ViewInjector*.*', 
           '**/BuildConfig.*', 
           '**/Manifest*.*'] 
      ) 


      additionalSourceDirs = files(coverageSourceDirs) 
      sourceDirectories = files(coverageSourceDirs) 
      executionData = files('../app/build/jacoco/testDebugUnitTest.exec') 

      reports { 
       xml.enabled = true 
       html.enabled = true 
      } 
     } 

和buildTypes添加此

testCoverageEnabled = true
