Smarthome: Eclipse compilation errors in core bundles - Annotations

[doandzhi]

Hello, I am facing compilation problems on org.eclipse.smarthome.core bundle. The compiler says

_"The annotation @NonNull is disallowed for this location"_.

I checked which version of org.eclipse.jdt.annotation and it is 1.1.0 which according to this this article is not compatible with Java 8. Tried to delete the whole bundle pool in case it uses cached jars from there but this didn't solve the problem. There is a newer version of the same .jar in the bundle pool but eclipse uses the older one.

Does anyone have this problem too, and how could it be solved?

I can confirm the problem with Eclipse Neon Build id: 20160613-1800 and the latest changes from the master branch.

@doandzhi Do you also have Eclipse Neon? Does it work in maven for you?

[doandzhi]

Yes it is built successfully in Maven.
I use Eclipse Version: Mars.2 Release (4.5.2)
Build id: 20160218-0600

@doandzhi: Oh, Mars is even older that Neon. By that time these annotations where not fully supported. We would kindly ask you to update to Eclipse Oxygen since this is our official development environment: https://www.eclipse.org/smarthome/documentation/development/ide.html

@svilenvul: Does ESH compile clean with maven for you? If not what is the error message? And if it does, would you also please update to Oxygen?

[svilenvul]

Yes, ESH compiles clean with maven. I will update to Oxygen.

After updating to Eclipse Oxygen the issue is resolved. Thanks a lot :)
