This plugin does not support incremental compilation

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Change one source file of the project
2. run 'mvn compile' 
3.

What is the expected output? What do you see instead?

One source file is compiled. What I saw is: all the unchanged files are 
compiled and it is time-consuming.

What version of the product are you using? On what operating system?

1.0.0-alpha8

Please provide any additional information below.

So please close this issue. Thanks.

Hi.

I don't understand your last comment.

Is this issue related to 
https://code.google.com/p/play2-maven-plugin/issues/detail?id=66?

We cannot say that Maven is or is not incremental. Maven uses 
maven-compiler-plugin for compilation. For Play! projects this plugin 
executions should be skipped and sbt-compiler-maven-plugin should be used for 
compilation. sbt-compiler-maven-plugin uses Zinc compiler 
(https://github.com/typesafehub/zinc) internally, provided by SBT team. It's 
incremental for sure.

Yes. That issue is related to issue 66. Our project is a Play2 project. So the 
compiling is incremental as Zinc is used. But for test-compile, it seems that 
the compilation is not incremental. I will provide the log in issue 66.
