Compile error after pub add cronet_http (missing: Java_JAVAH_EXECUTABLE)

[desmond1121]

Platform: Windows

After flutter pub add cronet_http, my project compiles error with:

CMake Error at C:/Program Files/Microsoft Visual Studio/2022/Community/Common7/IDE/CommonExtensions/Microsoft/CMake/CMake/share/cmake-3.28/Modules/FindPackageHandleStandardArgs.cmake:230 (message):

  flutter/ephemeral/.plugin_symlinks/jni/src/CMakeLists.txt:31 (find_package)

Error: Unable to generate build files

I double check this issue by removing cronet_http dependency and then the project runs successfully.

This doesn't make sense, javah already deprecated (javah) and we can use javac -h now.

@desmond1121 I assume that you are trying to run your application on Windows (not that you are targeting Android on your Windows machine).

Same problem. I add cronet_http to app, (support windows and android both), when RUN flutter build windows, I got this error.

CMake Error at C:/Program Files/Microsoft Visual Studio/2022/Community/Common7/IDE/CommonExtensions/Microsoft/CMake/CMake/share/cmake-3.29/Modules/FindPackageHandleStandardArgs.cmake:230 (message):

is there any way to solve this.

I got a workaround：

1. add jdk and maven
   choco install openjdk --version=17.0.2
   choco install maven
2. add JAVA_HOME to WINDOWS env
