How do you force gradle to print or log all compil

问题:

I'm trying to see the exact compiler commands (in my case gcc) used by gradle during execution of all build tasks. Running with --debug doesn't output these commands, and output files in build/tmp don't have them either. I'm currently using Gradle 2.6

回答1:

See $projectDir/build/tmp

You should have a folder structure that looks something like:

├───compileMainSharedLibraryMainCpp
│       options.txt
│       output.txt
│
├───compileMainStaticLibraryMainCpp
│       options.txt
│       output.txt
│
├───createMainStaticLibrary
│       options.txt
│       output.txt
│
└───linkMainSharedLibrary
        options.txt
        output.txt

options.txt contains the options passed to the compiler/linker etc, and output.txt contains the output of the compiler/linker.

The following snippet in build.gradle prints options (not complete command line):

toolChains {
    gcc(Gcc) {
        eachPlatform { 
            cppCompiler.withArguments { args ->
                println "----> C++ args: " + args
            }
        }
    }
}
