Change your compiler to use the modern java syntax.

Got the same error. Using Java 1.8. What is the minimum version needed?

[blakgeek]

@Robertbaelde Make sure you're not only using running 1.8 but also that you have the -source flag set to 7 or higher. The source flag tells the compiler the version of the syntax to enforce regardless of the actual version of java being used.

@blakgeek Thanks for your really quick reply! Tried that allready but got the following error back: Error: The platform "8" does not appear to have been added to this project.

I'm not sure how you tried to set the value. Look at SO link https://stackoverflow.com/questions/29386152/override-java-version-when-building-a-cordova-project-with-gradle

You need to override it in your build-extras.gradle like this

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

Be aware this file will be lost if you remove the android platform. It's probably a good idea to keep a copy someplace other than in the platform/android directory. I have a hook that copies it from my project root into the platform directory. https://gist.github.com/blakgeek/f70f57910608764c65fd97abcacb63f7
