Okay, what worked for me was adding all the sub-projects(libraries) that you plugin uses as main-libraries of yout cordova project.

Here what I did: Copy all the libraries to libs, go to eclipse>build path>order and export>Mark everything. After that, you have to create a build-extras.gradle file on your root/platforms/android folder. Put this code on your file:

ext.postBuildExtras = {
android {
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_7
        targetCompatibility JavaVersion.VERSION_1_7
    }
    allprojects {
        compileOptions {
            sourceCompatibility = JavaVersion.VERSION_1_7
            targetCompatibility = JavaVersion.VERSION_1_7
        }
    }
}
}

Keeping referencing in the subprojects, though. You have to make the reference from the project and the subproject (not sure why, but worked.).
