    If you intend to sink data to S3, you will need to download a missing JAR:
        wget -O #{libexec}/lib/jets3t-0.7.1.jar http://repo1.maven.org/maven2/net/java/dev/jets3t/jets3t/0.7.1/jets3t-0.7.1.jar

    system "mvn", "compile"
    libexec.install %w[bin conf lib]
    bin.mkpath
    (bin + "flume-ng").write flume_ng_script()
  end
  
  def test
    system "flume-ng"
  end
