maven-plugin - Clover 0% Coverage with multiple source directories + build-helper-maven-plugin

Question

我们的 java 应用程序有多个源文件夹，并使用 build-helper-maven-plugin 从所有文件夹中读取源文件，但是在这里，当我在应用程序上运行三叶草时，它会生成 clover.xml

coveredelements = 0
coveredconditionals = 0 
coveredmethods = 0
coveredstatements = 0

所有其他指标都有数字

为什么很少有指标为 0，是我在插件设置中遗漏了什么吗？

Answer 1

它可能会影响您配置中的设置 includesAllSourceRoots: false

参见文档:http://openclover.org/doc/maven/latest/instrumentInternal-mojo.html#includesAllSourceRoots

根据文档，如果设置为 false，则仅 ma​​in 源根 src/main/java 将被使用。
