What's Trident-java

Trident-java is a lightweight SDK that includes libraries for working with TRON system contracts and smart contracts.Trident-java makes it easy to build TRON applications with java.

Functions include:

• Offline address generation

• Offline transaction construct

• Offline transaction signature

• java-tron full node API support

Building the source

Building trident-java requires git and 64-bit version of Oracle JDK 1.8 to be installed, other JDK versions are not supported yet.

Clone the repo and switch to the master branch

$ git clone https://github.com/tronprotocol/trident.git
$ cd trident
$ cd trident-java
$ git checkout -t origin/master

then run the following command to build trident-java, the trident-0.7.0.jar file can be found in build/libs/ after build successful.

$ ./gradlew clean build -x test

Install trident-java

trident-java has set compatibility for jdk8 and can be used as a dependency. You can also add compatibility settings before compiling, located in trident-java/build.gradle, 'subject' item:

java {
        sourceCompatibility = JavaVersion.VERSION_1_8
        targetCompatibility = JavaVersion.VERSION_1_8
        // Add any compatibility 
    }

1.Repository settings

Add Bintray to Gradle repositories:

repositories {
    mavenCentral()
}

2.Choose required packages

trident-java includes three packages:

• abi---This contains datatypes and ABI encoders/decoders.
• core---This contains the wrapping functions for easily interacting with TRON system and smart contracts.
• utils---This contains tools including encryption, conversion, Etc.

3.Gradle dependencies

trident-java interacts with the TRON network through GRPC, Protobuf & GRPC related packages are required.

dependencies {
    // protobuf & grpc
    implementation 'com.google.protobuf:protobuf-java:3.11.0'
  
    implementation 'io.grpc:grpc-netty-shaded:1.31.0'
    implementation 'io.grpc:grpc-netty:1.31.0'
    implementation 'io.grpc:grpc-protobuf:1.31.0'
    implementation 'io.grpc:grpc-stub:1.31.0'
  
    implementation "org.bouncycastle:bcprov-jdk15on:1.68"

    implementation fileTree(dir:'../core')
    implementation fileTree(dir:'../utils')
    implementation fileTree(dir:'../abi')
    //if you are using the *.jar files, ues the following line
    implementation fileTree(dir:'your path', include: '*.jar')

    implementation 'com.google.guava:guava:28.0-jre'
}
