## [Java] Class JavaExec

- org.gradle.api.tasks.JavaExec

- All Implemented Interfaces and Traits:
    JavaExecSpec

      public class JavaExec
      extends org.gradle.api.internal.ConventionTask

  Executes a Java application in a child process.

  Similar to Exec, but starts a JVM with the given classpath and application class.

       apply plugin: 'java'

       task runApp(type: JavaExec) {
         classpath = sourceSets.main.runtimeClasspath

         main = 'package.Main'

         // arguments to pass to the application
         args 'appArg1'
       }

  The process can be started in debug mode (see getDebug()) in an ad-hoc manner by supplying the `--debug-jvm` switch when invoking the build.

       gradle someJavaExecTask --debug-jvm
