# intellij

when working with kotlin sonatype projects release profiles in maven i have gone with jvm-target 16. IJFW!
however when im using intellij run/debug buttons i have constant headaches i had to make this release profile special to use 16 because "1.8<->16" cannot inline code compiled in the other.
And then, also "your project is using a later version of the plugin than 1.5.10 check for updates"

1. is 1.8 the irrefutable end-state of kotlin at this time?
2. is there an online repo of kotlin plugins i can sideload into intellij ?
