There has been a possible solution for the Eclipse IDE setup years ago as the code base had been part of Eclipse SmartHome:
eclipse-archived:master ← maggu2810:external-null-annotations
opened 07:31AM - 08 Sep 17 UTC
This commit adds initial support for external annotations.
There is a new pro… ject "eclipse-external-annotations" that must be
imported in the Eclipse IDE.
If added already some annotations:
* JRE
* Object.toString() returns a `@NonNull` String
* Collections.empty... returns a `@NonNull` reference
* Collections.singleton... returns a `@NonNull` reference
* Collections.synchronized... returns a `@NonNull` reference
* Collections.unmodifiable... returns a `@NonNull` reference
* slf4j
* LoggerFactory.getLogger(...) returns a `@NonNull` reference
If a project should use external annotations this needs to be configured
for the Eclipse IDE in the project settings of each project.
See [Configuring a project to use external annotations]
Open the project settings and navigate to "Java Build Path", "Library"
tab. Set the external annotation reference for "JRE System Library" and
"Plug-in Dependencies".
This has been already applied for the core and the core.things project.
For the headless consumption a "dedicated path" is possible
("-annotationpath location").
See [Headless consumption]
This setting has been already added to the POM file.
Add new annotations is very easy as it is supported by the IDE.

IIRC after the migration from PDE to Pure Maven projects it should be enough to add the LastNPE plugin to the Eclipse IDE (as I written in the topic @wborn comment above).
I used the EEA in the Eclipse IDE for some other projects, so in general it should work.
