Hi, I created a grade project (Visual C++=>Cross Platform=>Android=>Basic Application (Android,Gradle) and upload to TFS. Or is it classes/groovy/resources? This avoids polluting other contexts, such as the compilation classpath for your production source code. It also displays information about dependency conflict resolution. You can programmatically access the task graph to inspect it within the build script using Gradle.getTaskGraph(). OK. This declares a dependency on version 12.3 of the "app-magic" library, inside the "com.example.android" namespace group. All in all, its about isolating things from each other and reducing the risks of breaking a build accidentally! A dependency resolution rule overruled the default selection process.

There is no dependency relationship between tasks, one can be executed without the other. Dependency is mandatory execution of both task, in the required order, so dependency implies order. For example, dependencies are used to compile the source code, and some will be available at runtime. So, what are the inputs of our docsFileJar? When we run ./gradlew jar we get this output. Why don't we get infinite energy from a continous emission spectrum? I made a custom plugin. The task graph can be nicely visualised using the taskinfo plugin, which helps us understand the task graph for a specific task.
