DSM analysis fails with "No class files were found"
Answered
I have a project which is building fine and has a number of classes. I can perform all the different types of analysis but when I try to generate a DSM I get the "No class files were found". I see some references to this from 2007 but that was for Ant builds which doesn't apply here.
Any ideas?
This can be easily reproduced with, for example, this project: https://github.com/alibaba/fastjson

Can't reproduce in IntelliJ IDEA 2017.3.4:
Can you give the details of exactly what you did? I.e. what scope you used, whether you included test sources, etc, so I can try the exact same way? I've tried several ways so far and all failed.
I'm using the same version.
Scopes that fail: whole project, directory fastjson, custom scope "all places"
Used all the defaults:
Okay, but I assume you're experienced enough to know that "works on my machine" is not a solution.

Does Build | Rebuild complete without errors? Any errors in idea.log: https://intellij-support.jetbrains.com/hc/articles/207241085?
What IntelliJ IDEA version is used?
Can you delete .idea directory, reimport the project from pom.xml and rebuild, then try again?
Version 2017.3.4
Rebuilding has no errors in the IDE:

The log shows:

I quit IntelliJ, deleted the .idea directory, restarted, rebuilt, and tried again, but get the same error.
If I change the Java version to 1.8 (in Project Structure - Project SDK) then it works.
For some reason no classes are compiled on your system. Notice that target/classes directory is empty. Also the messages says 0 warnings, while this project produces a plenty of compiler warnings.
Enable debug logging for build.log file and share the complete build.log file with debug info after performing rebuild: https://intellij-support.jetbrains.com/hc/articles/206869619.
See also https://intellij-support.jetbrains.com/hc/articles/207241085 for the info how to enable debug logging for build.log.
Thanks for the info, I've reported a bug at https://youtrack.jetbrains.com/v2/issue/IDEA-186575, please follow for updates. See https://intellij-support.jetbrains.com/hc/articles/207241135 if you are not familiar with YouTrack.
Did you manage to get a repro using Java 1.7? Or do you still need me to get build log files files?
Yes, I did reproduce it with 1.7.
Ok, thanks! I'm unblocked for now too.
Quick question, is this feature only available for java in that it's searching for java compiled *.class files?
I tried running on a kotlin project whole project directory scoped and got this message
It should work with kotlin classes as well. I could test it with a sample kotlin project. Do you see your compiled classes in the projects view? Do you see the same issue when trying with the whole project ?
It would help if you could share a reproducer project and a screencast of the issue. You can upload it to https://uploads.jetbrains.com/.
