[FIXED] Gradle DSL - Eclipse Equivalent for IDEA Module Property

Issue

Good localtime,

I am in the process of updating legacy (4.8.1) Gradle build files for a big-McLarge-huge, multimodule project. We utilize an intellij.gradle file which has the following line (marked by comment):

idea {
    module {
        inheritOutputDirs = true // <-- HOW DO I DO THIS
        downloadJavadoc = true
        downloadSources = true
    }

    workspace.iws.withXml { provider ->
        def node = provider.asNode()
        def dynamicClasspath = node.component.find { it."@name" == "dynamic.classpath" }
        if (dynamicClasspath != null) {
            dynamicClasspath."@value" = "true"
    }
}

From the 4.8.1 DSL docs:

If true, output directories for this module will be located below the output directory for the project; otherwise, they will be set to the directories specified by IdeaModule.getOutputDir() and IdeaModule.getTestOutputDir().

Any ideas on what the Eclipse DSL equivalent of inheritOutputDirs? Should this be handled using the eclipseClasspath API? Right now everything is building fine, but the Eclipse Java builder is is flagging things.

Solution

Usually this would have been picked up through sourceSets but I can't see what your project looks like...

If your subproject uses Gradle to generate sources into /build/cxf/generated-sources directory, then you can tell Eclipse via Gradle DSL to include that as a source folder like this:

plugins { id 'eclipse' }

eclipse.classpath.file.whenMerged {
  // this is the brute-force approach; there is likely a better way to add a source folder
  entries << new org.gradle.plugins.ide.eclipse.model.SourceFolder('build/cxf/generated-sources', null)
}

Once this is run (via gradle eclipseClasspath) you should see a build/cxf/generated-sources folder under your project node in the Package Explorer or Project Explorer. Sort of like this:

NOTE: This is untested because I don not have a sample project to work with.
