Explanation of the 2 modules, and what fails > I have a java 9 maven project with 2 modules: {{apimod}} and {{clientmod}}. > Module {{clientmod}} depends on module {{apimod}} (those modules are both > Maven modules and Java 9 modules). > Also, i want module {{clientmod}} to be able to reuse not only production > code from {{apimod}}, *but also test code*. This is a common pattern, that I > used many times with Java 8. With Java 9 (it's the same with Java 10) it also > works fine, as long as i don't declare module-info.java (that is, as long as > I don't run with the module system). > But as soon as I do, enabling the test dependency seems to disable the > production dependency: {{api.Base}} (an {{src/main}} class of module > {{apimod}}) is no longer visible from {{qux.DerivedTest}} (an {{src/test}} > class of module {{clientmod}}). The test doesn't compile anymore. (_Note that > every class is in a different package to eliminate split packages as a cause > of the problem_) > This is with: Java 9.0.4 (it's the same with Java 10), Maven 3.5.3, > maven-compiler-plugin 3.7.0 > > h1.
