使用CPP插件編譯gradle中的C++代碼

Question

我正在編寫gradle腳本，我試圖編譯C++代碼，我的結構如下。我試圖在下面的機器上編譯我的代碼，它顯示了C++編譯器失敗，而我沒有得到與Maven的問題可以somel

我以下面的方式使用了Javah函數。

     stream -> buildProperties.load(stream) 
} 
//add the jenkins build version to the version 
def env = System.getenv() 
if (env["BUILD_NUMBER"]) buildProperties.ncdefBuildVersion += "_${env["BUILD_NUMBER"]}" 
version = buildProperties.anal 
println "${version}" 

//name is set in the settings.gradle file 
group = "com.rohit.singh" 
version = buildProperties.anal 
println "Building ${project.group}:${project.name}:${project.version}"
