Hi,

The plugin was built with Java 8 and you’re using Java 7. That is what the error means.

Actually the plugin does not require Java 8, so maybe it should be built using Java 7. Create an issue on github if you need it to work with Java 7. Otherwise just upgrade your jdk, now that Java 7 has been EOL since April 2015.

Regards, Mikael Brännström

Yes, I understood why that problem, but I don't understand why you're do not support the older JVM's. Is that difficult to fix? As myself, I have already a set of JVM's beginning from the 1.5 and to the 9-preview.

Sorry, I got confused about the github e-mail I got. I wasn't aware of the issue created.

Please use the version 2.2.1 released in April 13, which was actually rebuilt with Java 7.
