Properties editor reporting 'Unused property' for all entries

Arvind,

I use the Ultimate Edition, but assume this should work the same on both.  

1. Hover over the yellow lightbulb and click the drop down on it
2. Next, click on the "expand arrow" to the right of "Remove Property", this will bring up additional options (see screenshot below)

Thanks Stuart. I have hundreds of properties, and it's a shared project.

I'd prefer a way to have intellij recognize the way these properties are being used currently: ${key}

Thanks!
Arvind

Hello.

Is there some standard for such references? I've browsed the java API: http://docs.oracle.com/javase/7/docs/api/java/util/Properties.html and find nothing similar.

Thank you,
Alexander.

Hi Alexander, Just simple variable/parameter substitution: http://azkaban.github.io/azkaban2/documents/2.1/jobconf.html for example usage.
${key} is typically found to be an acceptable way to use (and re-use) variables within strings and have them expanded at run-time.


Thanks!

Thank you. If I get it correctly, this is not something widely adopted, but rather a particular tool's innovation. It's Ok, but implementing this would require to preserve other users from unexpected consequences. Typically such problems are solved with creating a custom IDEA plugin purposed to work with specific tool.

If you like, you can create a feature request in our tracker anyway: http://youtrack.jetbrains.com/issues/IDEA

Alexander.

Arvind,
I've been wanting to get my hands dirty & dive into the CE source. I checked it out yesterday & have started exploring how to implement a custom plugin. I'll reply to this thread if I'm able to figure it out. It's always easier to learn when you have a purpose. :)
I'd still recommend creating a feature request, per Alexander. I've had success with that path here. If you open RFE, can you add the link to it to this thread?
Cheers!

Hi All,

I have a similar kind of issue and I already wrote my own plugin to cover some specific needs in the company I'm working for.

I already have an own GotoDeclarationHandler that will show the references of a key if I do a CTRL + click 

but I guess that I missed something somewhere as the keys are still greyed out.

maybe I did it wrongly ? 

here is the source file of my handler

https://github.com/alain57/swissas-dev-tools/blob/master/src/main/java/com/swissas/handler/PropertiesKeyToUsage.java

basically what it does : 

it reads a java file that contains the real usages , if it found one it will return the usages of the _Message file.

Hi, I have similar problem. I use ultimate version.

I have common.properties like:

foo=FOO (yellow)

bar=BAR (grey: unused property)

the difference between the two is that foo is used in constructor-arg and bar is used in property:

<bean id="blabla" class="com.example.Moo">
    <constructor-arg name="foo" value="${foo}"/>
    <property name="bar" value="${bar}"/>
</bean>
