Task 'make' not found in root project

[Mehmet Emre Aydinli]

Hi,

I have a java library that is part of a larger app project. It uses JNI to use a .cpp.

I am using Android Studio, and Gradle. When I do "gradle build" everything works beautifully and I can see everything built. However, when I do "gradle make" (same as Menu --> Build --> Make Project), I get "Task 'make' not found in root project" Somehow "gradle make" cannot find "make" to use for ndk-build. I am using Android.mk and Application.mk . 

What do you think?

BTW, my native code is in C++

Try "gradle build".

Yes, as I said in the original post, "gradle build" works. I am trying to understand why "gradle build" works and "gradle make" doesn't.

To use Android.mk with Gradle, you had to modify your build.gradle files. What changes did you introduce?

I have a few parts in my build.gradle:

- task ndkBuild

task ndkBuild(type: Exec) {
    if (Os.isFamily(Os.FAMILY_WINDOWS)) {
        commandLine 'ndk-build.cmd', '-C', file('src/main/').absolutePath
    } else {
        commandLine 'ndk-build clean', '-C', file('src/main/').absolutePath
        commandLine 'ndk-build', '-C', file('src/main/').absolutePath
    }
}

- dependsOn block to make sure ndkBuild happens before javac

 tasks.withType(JavaCompile) {
    compileTask -> compileTask.dependsOn ndkBuild
}

Then there are misc parts which builds the version text, creating and zipping the deliverables folder.

This really looks strange. I don't have a gradle task make, but for me Menu --> Build --> Make Project performs gradle build.

Best luck,

In case anybody stumbles upon this thread, here is how I worked around it. I created a separate project my jni library from which I build the shared object and the jar. Then I include those in the main app project.
