Any idea how can this be fixed?

[emccorson]

This is caused by a plugin using Java features that aren’t supported by your Java version. It looks like you are using Java 6. Is this on Monaca’s remote build service? Remote builds use an recent enough version of Java that this shouldn’t be a problem, unless you have specifically configured to use Java 6.

[shubhanan]

Thanks @emccorson. Yes this is on Monaca’s remote build service via Localkit. I’m not sure there’s specified a version of Java set to be used while on remote build… how do I check this?

[emccorson]

Actually, more likely is that this is a problem with OneSignal than the Java version, since I’ve seen this error in other places.

What’s the specific name of the plugin you are using?

[shubhanan]

Oh, okay. I’m using the plugin from “https://github.com/OneSignal/OneSignal-Cordova-SDK”, it is named as “onesignal-cordova-plugin”.

What’re my options out from here? Any suggestions from the past encounters of this error?

[emccorson]

@shubhanan I think it is the same problem as here: https://community.onsen.io/topic/3833/urgent-error-when-build-for-release-of-an-ios-app

See that link for a solution.

Thank you, @emccorson! The build succeeded once I set the version to 2.7.0.

Hopefully OneSignal team figures this out in the near future!
