Building a sub-project of a Gradle build, where another sub-project is Android

[dhoskins (Douglas Hoskins)]

I have a Gradle project with three sub-projects: an Android sub-project, a “core” sub-project and a non-Android sub-project.

Both the Android and non-Android projects depend on the Core project.

I would like to make the non-Android project buildable without having Android development tools installed on the machine. However this is currently not possible for me, because the Android SDK’s presence is required for the configuration phase. I get this error:

> failed to find target android-21 : /

How can I set up my project so that the non-Android component can be built without having these SDKs installed?

"Weak" dependencies in a multi-project setup

I have a simple multi-project setup. Project A is an Android client and Project B is a Tomcat-based backend that the Android client accesses. These two projects do not share any code. The Project A requires the Android plugin. Now here is the problem: when you cd into Project B (Tomcat) and run “gradle build”, gradle apparently includes Project A to compute the task graph (because it is referenced in settings.gradle). The unfortunate thing is that this requires a developer for Project B also to …
