gradle：如何从根项目运行子项目的JUnit测试？

Question

I have a root project called "myRootPrj" and several child projects (a EJB project, a UI project and so on). The EJB project "myEJBPrj" contains also JUnit testcases (under myEJBPrj/src/test/java/... ).

In the build.gradle of the "myRootPrj" I have add:

dependencies {
  ...
  testCompile project(':myEJBPrj')
}

But when I call the "test" task of the "myRootPrj" I get:

 Skipping task ':test' as it has no source files and no previous output files.

Seems that the "myRootPrj" don't find any test classes ... right? Why that?

2 things

First, about your question How to run JUnit tests of a child project from the root project?

Just run gradle :myEJBPrj:test

Then, setting testCompile project(':myEJBPrj') in myRootPrj project means that this one will use myEJBPrj sources to compile myRootPrj test sources but you don't have any test sources in your root project to the test task is ignored.
