Configure the IntelliJ IDEA IDE

For Java development, in order to reduce development difficulty and improve development efficiency, developers should first select and configure a Java integrated development environment, such as IntelliJ IDEA, NetBeans or Eclipse, etc. This article will take InteliJ IDEA as an example to introduce how to configure Java-tron integration development environment.

This article describes the configuration of the Java-tron integrated development environment in InteliJ IDEA. Java-tron nodes support to be deployed on Linux or MacOS operating systems, and rely on Oracle JDK 1.8, other versions of JDK are not supported. Before configuring the InteliJ IDE development environment, please ensure the following prerequisites:

  • Configure the development environment on Linux or MacOS operating system
  • Oracle JDK 1.8, git, InteliJ IDEA are installed

Configure InteliJ IDEA

The IntelliJ IDEA configuration steps are as follows:

  • Install Lombok plugin

    Search for lombok in [IDEA]->[Preferences]->[Plugins] to install Lombok plugin, Lombok makes Java-tron code more concise by adding annotations.

  • Enable Enable annotation processing configuration item image

  • Check the JDK version and make sure that Oracle JDK 1.8 is used in IntelliJ IDEA image

  • Download Java-tron source code

    Clone the Java-tron source code locally and switch to the develop branch.

    $ git clone
    $ git checkout -t origin/develop

Configure the code style check plugin

The Java-tron code style needs to meet the Google check style specification. In IDEA, you can use the Checkstyle plugin to check whether the code conforms to the Google check style specification. The installation and configuration process of the plugin is as follows:

  • Search for checkstyle in [IDEA]->[Preferences]->[Plugins] to install the plugin image

  • Code style configuration

    First, download the Java-tron code style check configuration file, then in the Checkstyle configuration page, click "+ ", choose to use the "checkStyleAll.xml" just downloaded, after adding that, you can see this file in the "Configuration Files" list, and finally click "Apply" to complete the configuration. image

    After configuring the Checkstyle plugin, you can use Checkstyle to check the code. Checkstyle can check a module or the whole project, and can also check a single file. Select "Check Current File" in the right-click menu of the file editor, and Checkstyle will check the file. If a code problem is detected, you need to modify it according to the prompts. Code can only be submitted when there are no code problems. image

Compile Java-tron

You can use the terminal to compile Java-tron with the following command in the Java-tron project directory:

$ ./gradlew clean build
The above compile command will execute all test cases, you can use -x test to skip the execution of test cases:
$ ./gradlew clean build -x test

You can also compile Java-tron in IDEA: Open the Java-tron project in IDEA and click "Build" -> "Build Project" to compile the project.

Run and Debug

Before running Java-tron, you need to create a working directory to store the database files and log files generated when the node is running.

$ mkdir /Users/javatrondeploy

In the "Run/Debug Configurations" configuration panel, specify the JDK version running Java-tron as java 8, and then configure the command parameters for running Java-tron, for example, specify the node configuration file through the -c parameter as config.conf.

"Working directory" is configured as the working directory of Java-tron created earlier. When Java-tron starts, it will look for the config.conf configuration file in this directory. Please make sure that config.conf has already been in this directory.


After the setting, click the "Apply" button to complete the configuration. Then you can click "Run"->"Run FullNode" in IDEA to start the Java-tron node or click "Run"->"Debug FullNode" to start the node in debug mode. After the node is started, Java-tron logs are stored in the working directory. image

If you want to debug the Java-tron code, you can set breakpoints in the Java-tron code and start it in debug mode, so that you can trace the debug code line by line. image
