config page error with java compile version

[tomasWade]

I get error when open the config page

com.intellij.diagnostic.PluginException: 
While loading class de.ax.powermode.power.ui.PowerModeConfigurableUI:
de/ax/powermode/power/ui/PowerModeConfigurableUI 
has been compiled by a more recent version of the Java Runtime (class file version 55.0),
this version of the Java Runtime only recognizes class file versions up to 52.0 [Plugin: de.ax.powermode]

I find https://github.com/axaluss/power-mode-intellij-plugin/issues/48 has same error, so try to down load latest jar from https://github.com/axaluss/power-mode-intellij-plugin/releases/tag/99.99

unluckly.. , It's not work. I extract the power-mode jar and check the real compile version :

[abc@abc-bladepro ui]$ javap -v PowerModeConfigurableUI|head

It's still 55, java 8 just support 52 for top. I am not very familiar with scala so can you compile it again?
