Using Child Process

To use Child Process, add the following dependency to the dependencies section of your build descriptor:

• Maven (in your pom.xml):

<dependency>
  <groupId>com.julienviet</groupId>
  <artifactId>childprocess-vertx-ext</artifactId>
  <version>2.0.0</version>
</dependency>

• Gradle (in your build.gradle file):

dependencies {
  compile 'com.julienviet:childprocess-vertx-ext:2.0.0'
}

Spawn child processes from Vert.x:

Process
  .create(vertx, "cat")
  .startHandler(process -> {
  process.exitHandler(code -> {
    System.out.println("Process exited: " + code);
  });
  process.stdout().handler(buf -> {
    System.out.println("Process wrote: " + buf);
  });
  StreamOutput stdin = process.stdin();
  stdin.write(Buffer.buffer("hello"));
  stdin.close();
}).start();
