------------------------------------------------------------------
I encountered this on 12.2 and 12.3.
My development computer is not and never will be connected to the Internet.
The first exception is thrown immediately when the Gradle options panel is
displayed. The exception is {{java.net.UnknownHostException:
services.gradle.org}}
Clicking "Apply" or "OK" whether or not changes are made results in the
initially reported NPE.
The [offending line in 12.3 is 770|http://example.com/]. The code assumes
{{cbGradleVersion}} will always have a selected item but in my case the combo
box is empty.
*Workaround:* To set a custom Gradle Distribution edit or create
{{${HOME}/.netbeans/12.3/config/Preferences/org/netbeans/modules/gradle.properties}}
and set the following properties:
{code:none}
gradleHome=/my/custom/gradleHome
useCustomGradle=true
{code}
