Short version
When I change resources in my app, then attempt to hot-deploy them, the files are deleted instead of updated from the target/ directory and I don't understand why.
Long version
I have a Java 8 + Tomcat 8 + Spring Boot + Thymeleaf project that I'm running out of IntelliJ. When I change files, such as CSS files from the src/main/resources/static/css directory, and run Update Resources or Update classes and resources, the file is deleted from target/classes/static/css instead of updated. Nothing is printed in the Tomcat logs about the file, nothing is printed in the IntelliJ logs (in ~/Library/Logs/IntelliJIdea13/idea.log) about deleting the file... it just disappears.
Tomcat 8 is set up as an external application server (not the built-in Spring Boot embedded server) with the following config. The only thing I've customized in the IntelliJ Run Configuration setup is to have specified CATALINA_BASE to the same value as the "Tomcat Base", like so:
Tomcat Home: /usr/local/tomcat8
Tomcat Base: /path/to/my/catalina/base
Java Env Vars: CATALINA_BASE=/path/to/my/catalina/base
... If I don't, CATALINA_BASE is set to /Users/me/Library/Caches/IntelliJIdea13/tomcat/Unnamed_demo_app, which seems to be a non-working clone of my real catalina base and I get 404's everywhere. This may be a red herring here, or the key to the mystery.
Extra, probably useless info
Here's the relevant (but uninteresting) output in idea.log:
INFO - ij.compiler.impl.CompileDriver - COMPILATION STARTED (BUILD PROCESS)
INFO - j.compiler.server.BuildManager - BUILDER_PROCESS [stdout]: Build process started. Classpath: /Applications/IntelliJ IDEA 13.app/lib/jps-launcher.jar:/Library/Java/JavaVirtualMachines/jdk1.8.0_31.jdk/Contents/Home/lib/tools.jar:/Applications/IntelliJ IDEA 13.app/lib/optimizedFileManager.jar:/Applications/IntelliJ IDEA 13.app/lib/ecj-4.3.2.jar
INFO - lij.compiler.impl.CompilerUtil - COMPILATION FINISHED (BUILD PROCESS); Errors: 0; warnings: 0 took 3709 ms: 0 min 3sec
The app is configured to do WAR deployments, with a custom catalina base containing a stock conf/server.xml and conf/web.xml, and various 3rd party libraries provided in lib.

I'm not sure really what is worth telling about this issue otherwise, though it doesn't feel like what I've provided is useful. Add a comment if there's any info I should add.
