I’m also experiencing a “beginner problem” after following the latest Eclipse IDE Setup
Note: I tried using multiple versions of Eclipse: the “latest release” 2019-12, 2019-09 and 2019-06 (as shown in the screenshots from the IDE Setup page). Switching versions didn’t solve my problem 
After importing my binding into Eclipse, I’m getting an error in pom.xml (on the opening <parent> tag):
| Description | Resource | Path | Location | Type |
|---|---|---|---|---|
| Plugin execution not covered by lifecycle configuration: com.diffplug.spotless:spotless-maven-plugin:1.24.3:check (execution: codestyle_check, phase: initialize) | pom.xml | /org.openhab.binding.unifi | line 5 | Maven Project Build Lifecycle Mapping Problem |
Searching the forums I found someone else had a similar problem:
However the steps in that thread didn’t resolve my issue
Maybe one of the Eclipse / IDE experts now what’s happening here?
Thanks in advance!
