Source files getting compiled multiple times #7

Closed matthewtsmith closed 8 years ago

matthewtsmith commented 8 years ago

I am using this plugin as part of a Play! Framework project. My source root is app. My application contains 53 Kotlin source files. When my application compiles it seems that everything gets compiled twice. Upon starting a build I see the following message: [info] Compiling 106 Kotlin sources Followed by: [warn] Duplicate source root: /Users/matthew/ActiveProjects/AppTree/Server/AppTreeCore2/app/Actions/APIKeyCheckAction.kt

For every kotlin source in my project. Once the compilation completes, it then starts over and compiles everything again.

I tried changing the kotlinSource to app in the build.sbt. When I do that it then outputs Compiling 159 Kotlin sources.

Prior to adding the plugin and using pure Java I did not have this problem. Here is my full output of a single build. Notice about half way through everything seems to start over:

can you reproduce this in and/or provide a minimal test case? there's no reason this should occur, unless play! does something weird.

matthewtsmith commented 8 years ago

Here is a sample project using the Play starter project: https://dl.dropboxusercontent.com/u/1451028/kotlin-play-sample.zip

I converted one source file to Kotlin. Just like in my project, it says its compiling two files. It then recompiles a second time before running.

Another interesting note, it seems that if I remove the 1 Kotlin source file the project does not compile twice. As soon as I add a Kotlin source file back into the project it begins noting the duplicate source root and compiling twice.

I can't compile the starter project
