Compile Exchange¶

To compile Exchange, follow these steps:

1. Clone source code from the nebula-java repository.

   git clone -b v1.0 https://github.com/vesoft-inc/nebula-java.git
   

2. Change to the nebula-java directory and package Nebula Java 1.x.

   cd nebula-java
   mvn clean install -Dgpg.skip -Dmaven.javadoc.skip=true -Dmaven.test.skip=true
   

3. Change to the tools/exchange directory and compile Exchange.

   cd tools/exchange
   mvn clean package -Dgpg.skip -Dmaven.javadoc.skip=true -Dmaven.test.skip=true
   

After compiling, you can see the structure of the Exchange directory as follows.
