我有一个Jenkins项目，对我的NodeJS项目进行SonarQube分析。我添加istanbul了对项目的依赖package.json。在Jenkins构建配置中，首先运行一个shell脚本：

cd ./project-name
npm install
node_modules/.bin/istanbul cover ./node_modules/.bin/_mocha path-to-unit-tests
node_modules/.bin/istanbul report cobertura
cd ..

这将安装依赖项，运行测试并生成代码覆盖率报告，并生成cobertura-coverage.xml文件。

在shell脚本之后，我运行Invoke Standalone SonarQube Analysis具有以下属性的代码覆盖：

sonar.java.coveragePlugin=cobertura
sonar.dynamicAnalysis=reuseReports
sonar.cobertura.reportPath=./project-name/coverage/cobertura-coverage.xml

Jenkins作业通过SonarQube仪表板成功运行，该仪表板描述了项目的各种内容，例如代码行，技术债务，问题等。但是，单元测试的代码覆盖率并未显示在SonarQube仪表板上。我确保仪表板具有“单元测试”小部件。

Version of SonarQube server: 5.2
Version of JavaScript plguin used on SonarQube: 2.9
Version of Cobertura plugin used on SonarQube: 1.6.3
Version of Cobertura plugin used on Jenkins: 1.9.7
Version of NodeJS plugin used on Jenkins: 0.2.1

我验证了工作区中是否包含该cobertura- coverage.xml文件。还检查了构建控制台日志，没有发现错误。我还尝试过使用LCOV格式来提高代码覆盖率：

sonar.dynamicAnalysis=reuseReports
sonar.javascript.lcov.reportPath=./project-name/coverage/lcov.info

即使在Jenkins工作区中生成了覆盖率报告，该报告也不会发布到SonarQube。我查看了工作区的内容并进行了验证。控制台日志显示生成的覆盖率报告。也试过了

sonar.dynamicAnalysis=reuseReports
sonar.javascript.lcov.reportPath=project-name/coverage/lcov.info

和

sonar.dynamicAnalysis=reuseReports
sonar.cobertura.reportPath=project-name/coverage/cobertura-coverage.xml

无济于事。我还分别重启了Jenkins和SonarQube服务器两次。在StackOverflow和其他地方查看了许多类似的问题，但没有找到任何有效的方法。

如果我添加一个构建后操作Publish Cobetura Coverage Report并在Cobertura xml report pattern字段中指定cobetura-coverage.xml文件的路径，则代码覆盖率报告确实会在Jenkins中发布。

查看了SonarQube中的后台任务日志，发现一个异常。

所以现在我将Shell脚本代码覆盖率生成行更新为

node_modules/.bin/istanbul cover -x node_modules ./node_modules/.bin/_mocha path-to-unit-tests

仍然有例外。基于max_allowed_pa​​cket，我没有MySQL，我需要提高MAX_ALLOWED_PACKET数据库设置中的值。刚完成此操作，然后重新触发了詹金斯的工作以进行SonarQube分析。异常消失了。SonarQube中的后台任务成功。但是我仍然没有在仪表板上看到单元测试代码的覆盖范围。没有其他例外。当我单击“配置小部件”按钮时，单元测试小部件上有“无数据”标签。当我回到仪表板时，“单元测试”小部件消失了。

知道我缺少什么吗？
