Question

I have a multiproject build with multiple war modules that depends on one jar module.

Both war and jar modules have dependencies over libraries like Spring, Hibernate an

Answer 1

I tried the above solution but found a problem. In my scenario I had a sub-project that had the above configuration. The problem was that the transitive dependencies of the sub-project were not being exported in the IntelliJ configuration, which caused the base project to stop compiling.

I did some digging around and stumbled upon this little gem which fixed the problem.

/**
 * Adds a configuration named 'provided'. 'Provided' dependencies
 * are incoming compile dependencies that aren't outgoing
 * dependencies. In other words, they have no effect on transitive
 * dependency management.
 */

configurations {
    provided
    providedPlusCompile.extendsFrom(compile, provided)
    testCompile.extendsFrom(providedPlusCompile)
}

sourceSets.main {
    compileClasspath = configurations.providedPlusCompile
}

plugins.withType(IdeaPlugin) {
    idea.module.scopes.PROVIDED.plus = [ configurations.provided ]
}
