必要时带上参数

1
clean cobertura:cobertura -Dcobertura.report.format=xml package -Dmaven.test.failure.ignore=true sonar:sonar -Dsonar.language=java

多模块项目通过Jenkins构建扫描上传到Sonar时,代码覆盖率很低,只覆盖了单模块的代码,这时可以通过配置JaCoCo解决该问题。

通过clean org.jacoco:jacoco-maven-plugin:prepare-agent jacoco:report-aggregate install 可在target下生成jacoco-aggregate覆盖相关报告

注：jacoco版本低于0.7.9 jacoco:report-aggregate参数可能不存在
多模块项目整合覆盖率还可以指定report目录
