InteliJ IDEA - https://www.jetbrains.com/idea/ Startup Setup - Application and be sure to select the native Java SDK 1.8, you can not use the built-in IDEA! Otherwise you will get an error when committing the database.
https://www.oracle.com/technetwork/java/javase/downloads/index-jsp-138363.html#javasejdk

1. Use InteliJ IDEA - New > Project from Version Control...
2. Choose ERA github
3. After load project - import Gradle project
4. Install Lombok (Settings - Plugins)

1. select Application, set org.erachain.Start
2. Set Working Directory for new Application to \ERA
3. select ERA_main module

1. Select Gradle build
2. Set Task: build
3. Set Arguments: --exclude-task test

Make in folder file startARGS.txt (see example in z_START_EXAMPLES folder)

The description of the application launch keys is in the file:
ERA\z_START_EXAMPLES\readme.txt

You can also specify startup keys in startARGS.txt file - see example in startARGS_example.txt

For set version in JAR application set String versionEra = in file build.gradle.
For set version in running from IDEA application set controller.Controller.version

For MapDB to work correctly Java 1.8 (vers 8) is required and the project is built and tested with this version. Otherwise it will cause an error when you commit and close the database:

DCSet.close:1674 - java.io.IOException: The requested operation cannot be performed on a file with a user opened mapped section

The node can be built and installed wherever Java can run. To build and test this project, you will have to follow these steps:

sudo apt-get update
sudo apt-get install openjdk-8-jre                     # Ubuntu
# or
# brew cask install adoptopenjdk/openjdk/adoptopenjdk8 # Mac

git clone https://github.com/erachain/Erachain

sbt checkPR

sbt node-it/testOnly *.TestClassName
# or 
# bash node-it/testOnly full.package.TestClassName

sbt packageAll                   # Mainnet

sudo dpkg -i node/target/*.deb

Connect to server via SSH.
Install the necessary packages to run a full node.

sudo apt install screen

sudo apt install unzip

sudo apt -y install openjdk-8-jre

Download the full node archive

wget https://github.com/erachain/Erachain/releases/latest/download/Erachain.zip

Unzip the archive and navigate to the folder.

unzip Erachain

cd Erachain

Use the screen program to create a new session

screen -S erachain

Run a full Erachain node. Use the specified parameters:

java -jar erachain.jar -pass=123456789 -seed=1:new:123456789 -nogui -rpc=on -rpcallowed=127.0.0.1

If necessary, the values of the following parameters can be changed:

• The -pass parameter contains the password required to unlock the wallet. Replace 123456789 with the value you wish.
• The -seed parameter contains information about the seed and is divided into sub-parameters:
  • The first sub-parameter is responsible for the number of accounts to be created.
  • The second sub-parameter is responsible for the seed itself. Valid values for this parameter are any existing seed or "new" to create a new seed.
  • The third sub-parameter is responsible for the password. Here it's necessary to duplicate the password from the -pass parameter

Collapse the erachain session: Ctrl+A+D

Run a full Erachain node in command line mode:

java -jar erachain.jar -cli

Use this command to unlock the wallet:

post wallet/unlock 123456789

To find out the received address, enter the following:

get addresses

Also, be sure to save seed. You can use it to log in to your web wallet:

get wallet/seed

If you need to restart the machine and then go to the already created wallet, change the startup line a little, because the account information is already saved.

java -jar erachain.jar -pass=123456789 -nogui -rpc=on -rpcallowed=127.0.0.1
