How to Build

Prepare dependencies

• JDK 1.8 (JDK 1.9+ are not supported yet)
• On Linux Ubuntu system (e.g. Ubuntu 16.04.4 LTS), ensure that the machine has Oracle JDK 8, instead of having Open JDK 8 in the system. If you are building the source code by using Open JDK 8, you will get Build Failed result.
• Open UDP ports for connection to the network
• MINIMUM 2 ENERGY Cores

Build and Deploy automatically using scripts

• Please take a look at the Tron Deployment Scripts repository.

Getting the code with git

• Use Git from the Terminal, see the Setting up Git and Fork a Repo articles.
• develop branch: the newest code
• master branch: more stable than develop. In the shell command, type:

git clone https://github.com/tronprotocol/java-tron.git
git checkout -t origin/master

• For Mac, you can also install GitHub for Mac then fork and clone our repository.

• If you'd rather not use Git, Download the ZIP

Including java-tron as dependency

• If you don't want to checkout the code and build the project, you can include it directly as a dependency

Using gradle:

repositories {
   maven { url 'https://jitpack.io' }
}
dependencies {
   implementation 'com.github.tronprotocol:java-tron:develop-SNAPSHOT'
}

Using maven:

...
<repositories>
  <repository>    
      <id>jitpack.io</id>
      <url>https://jitpack.io</url>
  </repository>
</repositories>
...
<dependency>
    <groupId>com.github.tronprotocol</groupId>
    <artifactId>java-tron</artifactId>
    <version>develop-SNAPSHOT</version><!--You can use any of the tag/branch name available-->
</dependency>

Building from source code

• Build in the Terminal

cd java-tron
./gradlew build

• Build in IntelliJ IDEA (community version is enough):

  Please run ./gradlew build once to build the protocol files

  1. Start IntelliJ. Select File -> Open, then locate to the java-tron folder which you have git cloned to your local drive. Then click Open button on the right bottom.
  2. Check on Use auto-import on the Import Project from Gradle dialog. Select JDK 1.8 in the Gradle JVM option. Then click OK.
  3. IntelliJ will open the project and start gradle syncing, which will take several minutes, depending on your network connection and your IntelliJ configuration
  4. Enable Annotations, Preferences -> Search annotations -> check Enable Annotation Processing.
  5. After the syncing finished, select Gradle -> Tasks -> build, and then double click build option.
