intellij flags properties set by maven-resources-plugin as "cannot resolve symbol"

Question

In my project's POM, I use maven-resources-plugin to set some properties from a file. However, Intellij flags these property references in the POM with the error "cannot resolve symbol", presumably because it cannot see them being defined anywhere. Is there a way to suppress this error?

If you hit alt-enter, is there an option where you can disable the inspection? — vikingsteve, Jul 02 '13 at 13:40
@vikingsteve no, the only options are "merge tags" and "split current tag" — Andy Dennie, Jul 02 '13 at 15:10
Wondering then if you are able to define them with blank values and then overwrite them with the maven-resources-plugin? — vikingsteve, Jul 02 '13 at 20:00

Warning: The solution to define the property blank as vikingsteve mentioned is very dangerous because in Maven 3 properties which are declared in pom.xml could not be changed by other plugins.

So if you have one plugin which sets a property and another plugin which reads the value of the property it will always get an empty string if you initialize it in the pom.xml.

In fact you can't define it in the pom.xml but i have no idea what i can do to eliminate the IntelliJ IDEA warning. For now i have to disable the "Maven model inspection". :-(

@ the user who have down-voted my answer (maybe @vikingsteve ?): can you please explain why you have down voted my answer? I can't see any error. – Josef Reichardt Aug 30 '16 at 13:39
probably because you were unfortunately also not able to provide a better solution, a final answer – avalancha Nov 22 '16 at 10:36

The best way I see to solve the issue is to use the following comment:

<!-- suppress UnresolvedMavenProperty -->

Empty properties are not overwritten or may be a risky operation as @Josef mentioned.

Yes, you can open Settings (spanner icon), go to Project Settings -> Inspections and then disable the inspection Maven -> Maven Model Inspection.

Alternatively, you might like to try defining "blank" values for the properties, and see if the plugin successfully overwrites them.

<properties>
     <myproperty></myproperty>
</properties>

Good luck!

The setting didn't have any effect for me, but the empty property worked. – Andy Dennie Nov 01 '13 at 18:09
Sry, but this solution isn't correct! Please see my Answer below. – Josef Reichardt Aug 30 '16 at 10:28

Error “cannot resolve symbol” can occur if you open a directory maven project, but intellij project has not yet been created. Why does the "Maven model inspection" there is such a relationship - is not clear, but it helped me.

Hey Stas, in either case you should edit this and clarify what you mean by the model inspection. I can't tell if you're asking a question or proposing a solution. Hope this helps! – jamesmortensen Nov 03 '13 at 00:15
I mean, that there is a project - "Inspection" is working correctly. There is no "idea"-project, the properties are highlighted as "cannot resolve symbol". – Stas Yak Nov 07 '13 at 07:08
