Jacoco Gradle jacocoTestReport任务失败生成报告时出错

我正在使用Gradle 1.6 .

我运行以下命令，它适用于所有项目
gradle clean build jacocoTestReport

今天，我看到其中一个项目在“jacocoTestReport”部分失败了 . PS附加错误日志 .

The main error lines are ：

12：35：45.920 [错误] [org.gradle.BuildExceptionReporter]引起::创建报告时出错
....
12：35：45.924 [错误] [org.gradle.BuildExceptionReporter]引起：java.io.FileNotFoundException：/ production / jenkinsAKS / workspace / MFUSvc / src / java-test / com / thc / ids / ws / mfu / msg / formulary（是一个目录）

Few points to note:

这个项目正在构建没有错误但是今天我看到了这个错误 .
我尝试使用两个/不同版本的jacoco（如下所示） - jacocoTestReport任务在使用这两个版本的所有其他项目中都能正常工作，但是对于这个版本失败了 .

jacoco {
// toolVersion = "0.6.2.201302030002"
toolVersion = "0.7.0.201403182114"
// reportsDir = file（"$buildDir/customJacocoReportDir"）
}

在给定的src / java-test / ... / ...路径下，我看到一个有效的.java文件，在我的工作区中（一旦compileJava等Gradle任务完成，我看到build / classes / {main，test， integrationTest} / ...文件夹包含一个有效的.class文件（对于该路径，该路径显示在错误中并说“是一个目录” .

知道我错过了什么 .

This is what I have for jacocoTestReport task in /init.d/common.gradle file:

jacocoTestReport {
      group = "Reporting"
      description = "Generate Jacoco coverage reports after running tests."
      ignoreFailures = true
      executionData = fileTree(dir: 'build/jacoco', include: '**/*.exec')

      reports {
             xml{
                 enabled true
                 //Following value is a file
                 destination "${buildDir}/reports/jacoco/xml/jacoco.xml"
             }
             csv.enabled false
             html{
                 enabled true
                 //Following value is a folder
                 destination "${buildDir}/reports/jacoco/html"
             }
      }

      sourceDirectories = files('src/java')
      classDirectories =  files('build/classes/main')
}

更新：我知道为什么！ - main / java，test / java等的sourceSet 部分 . 每个main，test等部分的srcDir设置为'not_valid_value' - >在我的全局init.d级别"common.gradle"文件中，它's applied to allprojects . I have mentioned global sourceSet section in global common.gradle file so that I dont have to include common tasks/configurations for test, integrationTest etc tasks in each project' s build.gradle文件 . 现在，因为每个srcDir在全局级别设置为'not_valid_value'，我的假设是，这个无效的srcDir值将被实际有效的srcDir值覆盖（当Gradle构建系统将从每个值读取sourceSets节时个别项目's build.gradle file' s sourceSet部分为main，test等，或者它们将作为列表条目聚集在一起，即主srcDir将成为['src/java'，'not_valid_value'] ---当我在common.gradle中打印并运行项目gradle构建时，打印有效的俱乐部 Value ：
```
println ""
  println "sourceSets.main.allJava.srcDirs is set to : " + sourceSets.main.allJava.srcDirs
  println ""
```
Value 打印，不知道Gradle打印好的时候是否需要'报价：
```
sourceSets.main.allJava.srcDirs is set to : [/production/jenkinsAKS/workspace/MFUSvc/src/main/java, /production/jenkinsAKS/workspace/MFUSvc/not_valid_value]
```
因此，当我在jacocoTestReport任务中使用sourceSets.main.allJava.srcDirs for sourceDirectories变量时，它的传递并没有给我一个错误（正如我在帖子中提到的那样），即使main / java的srcDir变量是：在BUILD TIME中有['src / java'，'not_valid_value']，一个来自common.gradle，另一个来自项目的build.gradle sourceSet部分 . 我现在没有得到错误，但它现在打破了生成的报告中的HTML链接，也就是index.html ...请参阅下面的快照图像 .

当我在"common.gradle"全局文件中使用main / java的实际值，test / java（即srcDir 'src/java'或srcDir 'test/java'或srcDir 'src/java-test'）时，在sourceSet部分内部 - 或者如果我是jacocoTestReport任务的硬编码sourceDirectories变量----它是给我一些我在帖子 BUT 中为其他项目提到的相同错误，它的成功和我看到HTML链接正在jacoco HTML报告index.html中工作 . 因此，无论在哪个地方都有测试/ java，src / java-test树，在构建期间，都不会生成build / jacoco文件夹，因为没有测试是否存在失败的项目 . So, it still remains, why "src/java" or "src/java-test" is failing jacocoTestReport task for this particular project.

如果我在定义实际值时使用以下内容 src/java
```
sourceDirectories = files(sourceSets.main.allJava.srcDirs)
```
对于JacocoTestReport任务，它适用于正确显示覆盖率％信息，上面帖子中显示的错误消息现在显示为 NOT （可能是srcDir无效值 - 但我打印了sourceSets.main.allJava.srcDirs的值并且它在构建时显示['src/java'，'not_valid_value']，但它打破了源文件的HTML链接，即当您浏览jacoco HTML报告元素列时，您可以看到覆盖百分比，但在深度，当您单击该功能时/ class level，你看不到文件的源代码（你可以看到绿色/黄色/红色覆盖的行） .

如果我在sourceSets {.. main {java {srcDir'src / java'}}}中使用“src / java”或者在jacocoTestReport任务中使用sourceDirectories = files（'src，java'），那么我'我收到以下错误：
```
Caused by: java.io.FileNotFoundException: /production/jenkinsAKS/workspace/MFUSvc/src/java/com/thc/ids/biz/mfusvc/dto (Is a directory)
```
我在源代码控制中看到了其他类似的错误消息，其中包含路径“src / java-test”包含测试的src / java-test .
```
//The following works for showing coverage %, but can't see file content at func/class level in HTML report
  sourceDirectories = files(sourceSets.main.allJava.srcDirs)

  // Enabling/uncommenting The following line for sourceDirectories - shows both coverage % and at the deep level if you click func/class Element link in jacoco HTML report, you'll see file content with colored coverage per line BUT, it gives error in few projects not in all (as for some, jacocoTestReport is successful)
  //sourceDirectories = files('src/java')


  //classDirectories =  files('build/classes/main')


  //------------------------------------------
  // If I play with uncommenting the following, I see that jacocoTestReport task generating (is a directory) error message either for src/java-test or test/java -- in some projects.. NOTE: not in all projects.
  //additionalSourceDirs = files('test/java')
  //additionalSourceDirs += files('src/java-test')

  //additionalClassDirs = files('build/classes/test')
  //additionalClassDirs += files('build/classes/integrationTest')
  //additionalClassDirs += files('build/classes/acceptanceTest')
  //------------------------------------------
```
ATLEAST，有一点我很清楚，我现在正在寻找一些时间 . "Element"函数或类级别的列链接正在工作时我没有选择（sourceSets.main.allJava.srcDirs）或（sourceSets.main.java.srcDirs）这是我在一些博客中看到的 .

FINAL ANSWER ：1）最近有人对这个项目进行了渐变并进行了一些JIBX处理，并且很少有JIBX CLASS文件最终用于构建/ classes / main或其他/ ....文件夹树（它出现在我的错误消息中）后） . 结论：jacocoTestReport设置对于"html"部分是正确的，因为我们在build / classes /.../树中构建时插入了一些新的.class文件失败了，jacoco找不到源代码，因此它在哭for无法创建报告 .

我所做的一切..
```
build.doLast {
      delete fileTree (dir: "${buildDir}/classes", include: "**/JiBX_bindings*.class")
}
```
现在一切都很开心 .

2）现在，我在前面的评论中说过sourceSets.main.allJava.srcDirs正在工作......是的，就在那时，我在common.gradle文件中设置了srcDir的'src / java' . 后来，我决定将'not_valid_value'放在common.gradle文件中，就像GLOBAL级文件一样，你不知道项目源代码java是在src / java还是src / somefunkyfolder / java中 . 如果在项目的build.gradle文件/级别定义了相同的sourceSet定义，那么它将覆盖或实际上我应该从项目build.gradle和common的'not_valid_value'中说出srcDir'src / java'的实际有效值 . 一起吃 . 如果文件夹/文件不存在，Gradle就会忽略一些东西，所以我很好 . 为什么我们在common.gradle中定义了sourceSets..section - 因为，我们在common.gradle中定义了test 和integrationTest 以及jacocoTestReport任务...而不是在每个项目中放置那些80-100行的build.gradle .

3）现在，删除那些时髦的JiBx _ * ...类文件之后，它们被包含在项目的结果.jar构建工件中但是在jacocoTestReport任务之前 - 事情又回到了正常状态我学会了如何获取jacoco HTML报告元素链接工作 .
