Caused by: java.lang.NumberFormatException: For input string: "18-ea"Cause
During enabling of Plugins , when the java version is retrieved , instead of an integer value an alphanumeric value is returned.
The alphanumeric value (11-18-ea in this case) causes NumberFormatException
This error is related to a Debian Bug report - #982403
ℹ️ The bug is logged for Java -17 , however may occur for other versions too
Solution
Update the java version to similar version without options. Below KB assists with this requirement
