Get Eclair fat JAR file, either by downloading it directly from a repository or by compiling from source:

git clone https://github.com/ACINQ/eclair.git  
cd eclair  
mvn package

Create an eclairdata directory and put an eclair.conf file there with the following lines:

eclair {
	chain = "test"
	spv = false

	server {
		public-ips = ["127.0.0.1"]
		binding-ip = "0.0.0.0"
		port = 9096
	}

	api {
		enabled = true
		binding-ip = "127.0.0.1"
		port = 8086
		password = "pass"
	}

	bitcoind {
		host = "localhost"
		rpcport = 18332
		rpcuser = "foo"
		rpcpassword = "bar"
		zmq = "tcp://127.0.0.1:29000"
	}
}

Run Ecliar instance by issuing java -Declair.datadir=eclairdata/ -jar eclair-node.jar
Get Olympus fat JAR file, either by downloading it directly from a repository or by compiling from source:

git clone https://github.com/btcontract/olympus.git  
cd olympus  
sbt  
assembly

Run Olympus instance by issuing:

$ java -jar olympus-assembly-1.0.jar production "{\"zmqApi\":\"tcp://127.0.0.1:29000\",\"ip\":\"127.0.0.1\",\"privKey\":\"17237641984433455757821928886025053286790003625266087739786982589470995742521\",\"btcApi\":\"http://foo:bar@127.0.0.1:18332\",\"eclairSockPort\":9735,\"rewindRange\":1,\"eclairSockIp\":\"127.0.0.1\",\"eclairNodeId\":\"03dc39d7f43720c2c0f86778dfd2a77049fa4a44b4f0a8afb62f3921567de41375\",\"paymentProvider\":{\"quantity\":50,\"priceMsat\":2000000,\"url\":\"http://127.0.0.1:8080\",\"description\":\"Storage tokens for backup Olympus server at 127.0.0.1\",\"tag\":\"EclairProvider\",\"pass\":\"pass\"}}"

Note: Olympus config is provided as a command line argument instead of a file because it contains private keys (the one for storage tokens and for Strike). Don't forget to use space before issuing a command (i.e. $ java -jar ..., NOT $java - jar ...) so it does not get recorded in history.
