Deploying Java Projects

Zeabur supports deploying Java projects that use the Maven or Gradle build systems, with either native or Spring Boot frameworks.

Environment Setup

The available JDK versions are:

  • 19
  • 17 (default)
  • 11
  • 8
  • 7

Specifying JDK Version

You can specify the JDK version in pom.xml or build.gradle.

For example, if you're using Maven, add the following to pom.xml:


If you're using Gradle, add the following to build.gradle:

sourceCompatibility = 11

Specifying JVM Startup Parameters

You can override Zeabur's default JVM startup parameters with the javaArgs field in zbpack.json. You'll need to add the path to your jar file yourself.

  "javaArgs": "-Xms128m -Xmx512m -jar target/your-app.jar"
