Project in multi project can't find specific project dependency

I have a Multi Project wich has the following structure:

Where "plugins" is just a directory.

Now I have a couple classes inside "globalOptions":

And one class inside "commandPlugin":

The "CommandPluginTest" class uses"OptionExtension" and "OptionHandlerExtension" from the other project:

import at.lyze.plugin.globalOptions.extensionpoint.OptionExtension;
import at.lyze.plugin.globalOptions.extensionpoint.OptionHandlerExtension;

List<OptionHandlerExtension> optionHandlers = wrapper.getPluginManager().getExtensions(OptionHandlerExtension.class);
        for (OptionHandlerExtension optionHandler : optionHandlers) {
            logger.warn(optionHandler.getOption(getClass(), "TestOption"));
        }

My gradle build files look like:

"globalOptions":

dependencies {
    compile project(':pluginApi')
}

"commandPlugin":

dependencies {
    compile project(':plugins/globalOptions')
    compile project(':pluginApi')
}

When trying to run the "jar" task on every project I get the following error:

Note: Extension found in at.lyze.plugin.globalOptions.GlobalOptions$TestExtension
:plugins/globalOptions:compileJava
:plugins/globalOptions:processResources UP-TO-DATE

FAILURE: Build failed with an exception.

Have I done something wrong here or why does this fail? I can provide additional information if needed.

Running gradle 2.9

Edit:

Settings.gradle (Global project with every include)

rootProject.name = 'DarkOwlBot'
include 'pluginApi'
include 'core'
include 'plugins/globalOptions'
include 'plugins/commandPlugin'
include 'plugins/guiFeederService'

In addition to what @ReneGroeschke said, you should leave out the into ('classes') line here. You're altering the structure of the produced artifact.

Most likely, gradle has problems with the '/' in project names. By default the project name is also used to create the jar for the project. This likely results in wrong file paths.

I think your best options to solve this are:

  1. Change the include statements in your settings.gradle file to be
    include ':plugins:globalOptions' and reference globalOptions by compile project(':plugins:globalOptions')

  2. Change the include statement in your settings.gradle file to be
    include ':globalOptions' and configure the project directory explicit via project(':globalOptions').projectDir = file('plugins/globalOptions') and reference it in your dependency block via compile project(':globalOptions')
