假定项目 sp1 和 sp2 是项目 p3 的个子项目，如果您想这样做：

Assuming project sp1 and sp2 are subprojects of project p3, if you want to do:

dependencies {
    compile project(':p3:sp1')
}

然后，您需要将 settings.gradle 更改为：

Then you need to change your settings.gradle to:

rootProject.name = root

include ':p1'
include ':p2'
include ':p3'    // Keep this if this folder contains a build.gradle
include ':p3:sp1'
include ':p3:sp2'
