## Gradle runtimes

Gradle is also made up of several different processes that work together to "run the build", such as the Gradle daemon and the `gradlew` command.

Each process, or "runtime", applies different constraints to the code that runs in that process.
For example, each process has different supported JVMs and a different set of services available for dependency injection.

        String stderr
        int returnCode
    }

    static ExecResult exec(String command) {
        Process process = command.execute()
        def stdoutFuture = readStreamAsync(process.inputStream)
        def stderrFuture = readStreamAsync(process.errorStream)

        int returnCode = process.waitFor()
        String stdout = stdoutFuture.get()
        String stderr = stderrFuture.get()

				]
			},
			{
				"parallelizationMethod":{
					"name":"TestDistribution"
				},
				"subprojects":[
					"testing-jvm",
					"worker-processes",
					"files",
					"java-language-extensions",
					"build-cache-packaging",

  
  project3["root project"]
  build2 --> project3
  
  project4["project"]
  build2 --> project4

```

### Build process state

The "build process state" holds the global state of the build process and manages all the other state.

The build process state also includes state that is tied to a particular Gradle user home directory.
