推荐答案

我在build.gradle中缺少以下内容:

I was missing the following from my build.gradle:

jacoco {
    toolVersion = "0.8.6"
}

虽然很明显，build.gradle可以从其他gradle文件继承属性，并且由于我不知道的原因， jacoco 传递给一个子项目，但不能传递给另一个子项目.

While obvious, build.gradle can inherit properties from other gradle files and for reasons I can't figure out, jacoco was passing through in to one subproject but not to another.
