Xgboost: [jvm-package]How to build xgboost4j in win7-64bit system.

[baibaiw5]

I already built xgboost.exe and libxgboost.dll successfully in win7-b4bit system.
--But when I built xgboost4j using "mvn package",I got the following code check error:
$ mvn package

--Besides,In create_jni.bat ,it mentions xgboost4j.dll and "source library not found, please build it first from ..\windows\xgboost.sln";but in create_jni.sh,it mentions libxgboost4j.so.
I can not find xgboost.sln or xgboost4j.dll in git repository,How can I get them?

[CodingCat]

@baibaiw5 , I'm sorry that xgboost4j is not support for windows temporarily .....

[marcus-voss]

Any Plans on when this will be avail?

[lovetimil]

come arcross the same problem. where to get xgboost4j.dll,just xgboost4j.dll.

[alaeddinms]

Has xgboost4j.dll for windows been added? where to get it please?

Thanks

[syw2014]

I have the same errors, has it solved now?

[xmbipb]

Also have the same errors. Win 10 64 Bit.
Why is not it possible to provide a JAR somewhere?

[johnlevi]

Can support windows in 0.7?
I build it in eclipse(windows) still failed.

[sahil1421011]

Anyone get the solution for this issue ??? I hope now xgboost supported in windows.

[lujinyong168]

I hope now xgboost0.7 supported in windows.

[superbobry]

The JVM/Spark version does indeed support Windows. In fact, we test all incoming changes on Windows as well as Linux/OSX: https://ci.appveyor.com/project/tqchen/xgboost/
