Setup - HeroDevs Never‑Ending Support

Setup Instructions

NES for H2 Database 2.1.x requires Java 8.

Configure Registry

Create or update your registry configuration:

Maven (~/.m2/settings.xml)

<settings>
  <servers>
    <server>
      <id>herodevs-nes-registry</id>
      <username>any_text_here_not_used</username>
      <password>YOUR_NES_ACCESS_TOKEN</password>
    </server>
  </servers>
</settings>

Gradle (~/.gradle/gradle.properties)

herodevs_nes_registry_url=https://registry.nes.herodevs.com/maven
herodevs_nes_registry_user=any_text_here_not_used
herodevs_nes_registry_token=NES_TOKEN_HERE

See the guides for Sonatype Nexus or JFrog Artifactory for setup to the HeroDevs NES registry.

Update Build Configuration

Add the NES repository and dependencies to your build configuration:

Look up the latest artifact version in the "H2 Release Notes".

Maven (pom.xml)

<!-- Update H2 dependency version. Other option is using NES version for each H2 import -->
<dependencyManagement>
  <dependencies>
    <dependency>
      <groupId>com.h2database</groupId>
      <artifactId>h2</artifactId>
      <version>2.1.214-h2-2.1.215</version><!-- Updated Version -->
      <type>pom</type>
      <scope>import</scope>
    </dependency>
  </dependencies>
</dependencyManagement>

<!-- Add NES repository -->
<repositories>
  <repository>
    <id>herodevs-nes-registry</id>
    <url>https://registry.nes.herodevs.com/maven</url>
  </repository>
</repositories>

Gradle

buildscript {
  repositories {
    maven {
      url = uri("${herodevs_nes_registry_url}")
      credentials {
        username = "${herodevs_nes_registry_user}"
      }
    }
    mavenCentral()
  }
}

apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'idea'
apply plugin: 'application'

dependencies {
  implementation(platform("com.h2database:h2:2.1.214-h2-2.1.215")) // Updated Version
}

// Add NES Repository
repositories {
  maven {
    url = uri("${herodevs_nes_registry_url}")
    credentials {
      username = "${herodevs_nes_registry_user}"
      password = "${herodevs_nes_registry_token}"
    }
  }
  mavenCentral()
}

Build

In order to remove potential obstacles before building your project, make sure the following domains are whitelisted by your firewall/networking team:

registry.nes.herodevs.com
assets.nes.herodevs.com

This will ensure that your network/firewall allows connection to our registry.

Run your build tool:

Maven

mvn clean install

Gradle

gradle clean build

Verification

To verify your installation, check that:

Dependencies are downloaded successfully
No version conflicts are reported in your build
Your application starts without errors
