To make automated tests work in Idea:

1. Download https://github.com/ACINQ/eclair/commit/98bb7be70a4fc96242409b90fbf1ec9c5ff470e6 (latest release).
2. Compile Eclair with $ '/home/anton/apache-maven-3.6.3/bin/mvn' install -DskipTests (things need to be done this way to get eclair-tests jar file which is not included in prebuilt download package).
3. Download https://github.com/btcontract/plugin-hosted-channels.
4. Create a folder <HC>/lib/
5. Go to <Eclair> folder with compiled stuff.
6. Copy <Eclair>/eclair-core/target/eclair-core_2.13-0.5.1-tests.jar to <HC>/lib/.
7. Unpack <Eclair>/eclair-node/target/eclair-node-0.5.1-98bb7be-bin.zip, copy all <UNPACKED>/lib/*.jar to <HC>/lib/.
8. Open HC in Idea, go to File -> Project structure -> Modules -> Dependencies.
