由于没有 class 个文件，因此无法对项目覆盖率进行 JaCoCo 分析

Question

我正在使用 Bamboo、SonarQube 和 Maven 插件在 SonarQube 中生成 Jacoco 报告。它正在生成 jacoco.exec 文件，但如何在 SonarQube 中显示报告？以下插件我正在使用 '

Answer 1

build 08-Sep-2016 15:33:06 INFO: No JaCoCo analysis of project coverage can be done since there is no class files.

就像日志中所说的那样；检查您是否指定了以下内容：

sonar.java.binaries=classes directory, most likely target/classes

如果您还可以指定，效果会更好（这样就不会抱怨找不到某些 类）：

sonar.java.libraries=libraries directory, likely target/project/WEB-INF/lib
