I’m using the IntelliJ Ultimate IDE. I won a one year license at a PhillyJUG meetup raffle. The Ultimate edition provides server integration, a significant amount of framework support as well as a team of support people to resolve your issues that the community edition does not have. You can view a comparison. The server support is a mere convenience and isn’t required. It does create a more pleasant experience over the verbose Tomcat command line server arguments or the gradle configuration.

I keep getting burned every time I create a new Java webapp project in IntelliJ. When deploying the war file to the server, IntelliJ can not find it. I forget this issue exists because I don’t create Java webapps that often. I’m using Spring Boot or Dropwizard mostly with a built in server. I end up wasting an hour or so trying to understand the problem until I remember the issue. It is a documented issue with the default gradle build process. The issue can be found here, as well as a work around, but it hasn’t been integrated into updated releases for some reason. The comments on the issue page echo this. The first time this happened, I dug for hours before I ended up opening a support ticket. The team resolved my issue within a few hours. Below is an illustration of the steps.

Adding Tomcat configuration with the exploded war artifact. server setup

The war file can not be found with the default gradle build setting.
