Provided dependencies using Gradle (JetGradle) and Intellij Idea 13

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

Adding to the answer from Adrijardi, for Gadle 2.0 + not only did I have to change

scopes.PROVIDED.plus += configurations.provided

to

scopes.PROVIDED.plus += [configurations.provided]

I also had to change

provided project(":module-name") {
    transitive = false
}

to

provided (project(":module-name")) {
    transitive = false
}

Note the extra set of brackets on the second code sample

Answer 2

The best solution I found was to set the transitive "compile" dependencies from the jar module as provided using the following code in the Gradle configuration file:

apply plugin: 'idea'

configurations {
    provided
    provided.extendsFrom(compile)
}

idea {
    module {
        scopes.PROVIDED.plus += configurations.provided
    }
}

For Gradle 2.0+ modify the last bit to be like this:

idea {
    module {
        scopes.PROVIDED.plus += [configurations.provided]
    }
}

This solution works using the Intellij Gradle plugin and also the idea task in Gradle

I got this solution working based on the info on this urls: https://github.com/Netflix/RxJava/pull/145 http://www.gradle.org/docs/current/dsl/org.gradle.plugins.ide.idea.model.IdeaModule.html

I hope this helps someone else

Answer 3

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.

https://github.com/gradle/gradle/blob/ccddc438ce09293d84030ebe31668d739c8a228a/gradle/providedConfiguration.gradle

/**
 * 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 ]
}
