how to build demo with javac

[fzwqq]

Thanks for the tutorial.

Well, could you pls write a guide start from javac for the users who are not familiar with Gradle.

Thanks again.

when running the app, I had always got this.

Make sure you're using the same version of libtorch as the Java wrapper.

Thanks for replying.
I try to compile with javac and java command.
Specifically, the version of JDK and Libtorch are 1.8 and 1.5(stable Pre-cxx11 ABI) separately.
The dependence packages that I download are "pytorch_java_only-1.4.0.1.jar", "fbjni-java-only-0.0.3.jar" and "nativeloader-0.8.2.jar".

More details are shown below.

• libtorch
  
• jdk & LIBRARY_PATH
  
• the dependence package I download

1. Then, when I follow the tutorial step by step, it actually works.
   
2. However, when I use the command line, it output like this.

I am not sure what the version of the packages is definitely correct.
Thanks again.

Try running ./gradlew --info run. It will show you the exact command that it is running.

Thanks for the help.
After trying running ./gradlew --info run, I think I found the problem. Specifically, it is the version of pytorch-java-only. The detail is shown below.

However, I am really curious why the Gradle could work. In the tutorial, it indicates that only when using the "NIGHTLY" Libtorch, the code should invoke org.pytorch:pytorch_java_only:1.5.0-SNAPSHOT.

But I am pretty sure that my Libtorch is a 1.5 ""stable"" version. So, I have been always used the pytorch-java-only 1.4 instead of 1.5.
After changing the version of pytorch-java-only from 1.4 to 1.5, java executes normally.

Or, that's to say, I shouldn't install "stable". By default, it is only supporting "nightly", right?
