process-warden

Build Status

process-warden provides a safer wrapper around the built in Java Process and ProcessBuilder classes for executing native subprocesses.

Usage

With Java 6:

FinalizedProcessBuilder pb = new FinalizedProcessBuilder("myCommand", "myArg");
FinalizedProcess process = pb.start();
try {
  int returnVal = process.waitFor(5000);
} finally {
  process.close();
}

With Java 7 and try-with-resources:

FinalizedProcessBuilder pb = new FinalizedProcessBuilder("myCommand", "myArg");
try (FinalizedProcess process = pb.start()) {
  int returnVal = process.waitFor(5000);
}

Now With Stream Gobbling. The StreamGobbler will gobble up the input stream, error stream, or both in a separate thread to prevent from blocking your thread.

FinalizedProcessBuilder pb = new FinalizedProcessBuilder("myCommand", "myArg");
pb.gobbleStreams(true);
try (FinalizedProcess process = pb.start()) {
  int returnVal = process.waitFor(5000);
}

Installation

Add it as a maven dependency:

<dependency>
  <groupId>com.leacox.process</groupId>
  <artifactId>process-warden</artifactId>
  <version>1.1.0</version>
</dependency>
