I am a long time intellij user.
The company where I work is likely to introduce Rational Team Concert to our department shortly. I went to the RTC demo and it looks like a reasonable product, built around Eclipse, but I would rather not give up using IntelliJ.
Does anyone have experience of using non-eclipse IDEs with RTC?
Rational Team Concert's integration page says "Jazz Connect for IntelliJ IDEA enables developers using JetBrains to leverage the power of Rational Team Concert for source control, work item management, and collaboration services."
Also have a look at this page for other integrations of RTC.
I would say that it could, it looks like IntelliJ offers an version control integration point as does the Jazz SCM component, but I am not familiar enough with IntelliJ to say for sure(looks like ClearCase is already on the list so they are adding support for vendors), I would think that without a full fledged integration where your Work Items are integrated into your development RTC starts to loose it's flair but may be not for your management :)
