Running eclair

[valentinewallace]

Hi, I'm running into a NoSuchFileException error when trying to run eclair on an M1 Mac. Here are my steps:

• Download the eclair-node-0.7.0-a804905-bin.zip
• mv eclair-node/target/eclair-node-*.zip ./eclair-node.zip
• unzip eclair-node.zip && mv eclair-node-* eclair-node && chmod +x eclair-node/bin/eclair-node.sh
• Finally, run script_conf_file=/Users/valentine/.eclair/eclair.conf PATH="/opt/homebrew/opt/openjdk/bin:$PATH" ./eclair-node/bin/eclair-node.sh "-Declair.datadir=/Users/valentine/.eclair/"

Note that the script_conf_file argument was needed for eclair to see the conf file, couldn't find this documented anywhere 🤔

This results in this error in eclair.log:

Ohh, I think it's treating my conf file contents as plugin arguments? Sorry if this is noise, will keep digging...

[valentinewallace]

Got it working with

PATH="/opt/homebrew/opt/openjdk/bin:$PATH" ./eclair-node/bin/eclair-node.sh "-Declair.datadir=/Users/valentine/.eclair/" "-Declair.chain=regtest" "-Declair.bitcoind.rpcport=18443" "-Declair.bitcoind.auth=password" "-Declair.bitcoind.rpcuser=polaruser" "-Declair.bitcoind.rpcpassword=polarpass" "-Declair.bitcoind.zmqblock=tcp://127.0.0.1:28334" "-Declair.bitcoind.zmqtx=tcp://127.0.0.1:29335" "-Declair.server.port=9935" "-Declair.onion-messages.relay-policy=relay-all"

Marked as resolved

That's very surprising, the standard way of running eclair is to specify its data directory (default is ~/.eclair on linux/macOS). It there is an eclair.conf file in its data directory it will use it to load its configuration.
Can you check the first llines of eclair.log (in eclair's home dir) ? It should record which data directory was selected.

Just tried running PATH="/opt/homebrew/opt/openjdk/bin:$PATH" ./bin/eclair-node.sh "-Declair.datadir=/Users/valentine/src/test/" (which contains my eclair.conf) and I get these logs:

Hm, actually could be my conf file has a syntax error or something? Likely user error

[sstone]

Yes it looks like an error in the configuration file. We use lightbend's config library which is based kn HOCON (an extension of JSON). Default configuration is https://github.com/ACINQ/eclair/blob/master/eclair-core/src/main/resources/reference.conf but there are very few values that you need to override to get eclair to work. Can you share your eclair.conf file (which includes your local bitcoind's username and password which you may want to edit out)?

[valentinewallace]

Here's how my eclair.conf differs from the default: https://www.diffchecker.com/3920pbGm (you can hide the whitespace changes using "Tools" in the upper right). My conf is on the right! I'm using polar so didn't bother hiding passwords..
