Download Java packages using direct repository access

After you integrate Assured OSS with Security Command Center, Assured Open Source Software packages are hosted in an Artifact Registry repository that is created in a project that you control.

This page explains how you can connect to the Artifact Registry repository for Assured OSS to directly access and download the Java packages.

This document applies to the Assured OSS premium tier only. For the free tier, see Download Java packages using direct repository access for the free tier.

Before you begin

  1. Integrate Assured OSS with Security Command Center.

  2. Validate connectivity to Assured OSS for the requested service accounts.

  3. Install the latest version of the Google Cloud CLI.

  4. If you have installed the Google Cloud CLI previously, make sure you have the latest version by running the command:

    gcloud components update

Set up authentication

Artifact Registry supports the following authentication methods:

  • Authentication with a credential helper
  • Authentication with a password

The following sections describe how to set up these authentication methods.

Authenticate with a credential helper

Artifact Registry provides a Maven wagon and a Gradle plugin to use as credential helpers. This option provides the most flexibility.

To set up Application Default Credentials, see Set up authentication.

Set up your credential helpers

If you're using a credential helper to set up authentication, make the following changes based on the build tool.

Maven 

<project>
  <build>
    <extensions>
      <extension>
        <groupId>com.google.cloud.artifactregistry</groupId>
        <artifactId>artifactregistry-maven-wagon</artifactId>
        <version>2.2.0</version>
      </extension>
    </extensions>
  </build>
</project>

Gradle 

plugins {
  id "com.google.cloud.artifactregistry.gradle-plugin" version "2.2.0"
}

Authenticate using password

Authenticate using password when your Java application requires authentication with a specified username and password. Depending on your build tool, change settings according to the following instructions:

Maven

Add the following authentication settings in the settings section of the ~/.m2/settings.xml file. See the Maven Settings reference for more information. If the ~/.m2/settings.xml file doesn't exist, then create a new file.

<settings>
  <servers>
    <server>
      <id>artifact-registry</id>
      <configuration>
        <httpConfiguration>
          <get>
            <usePreemptive>true</usePreemptive>
          </get>
          <head>
            <usePreemptive>true</usePreemptive>
          </head>
          <put>
            <params>
              <property>
                <name>http.protocol.expect-continue</name>
                <value>false</value>
              </property>
            </params>
          </put>
        </httpConfiguration>
      </configuration>
      <username>_json_key_base64</username>
      <password>KEY</password>
    </server>
  </servers>
</settings>

Replace KEY with the base64-encoding of entire service account JSON key file. To do this, run the following command:

cat KEY_FILE_LOCATION  | base64

Replace KEY_FILE_LOCATION with the location of the service account JSON key file.

Gradle

Add the following line to your ~/.gradle/gradle.properties file so that the key is not visible in your builds or your source control repository.

artifactRegistryMavenSecret = KEY

Replace KEY with the private key from your service account JSON key file. For json_key_base64, the artifactRegistryMavenSecret contains the base64 encrypted password. For example, base64 -w 0 KEY.

In the build.gradle file, specify the repository settings using the following example:

repositories {
  maven {
    url "artifactregistry://us-maven.pkg.dev/PROJECT_ID/assuredoss-java"
    credentials {
      username = "_json_key_base64"
      password = "$artifactRegistryMavenSecret"
    }
    authentication {
      basic(BasicAuthentication)
    }
  }
}

Replace PROJECT_ID with the ID of the project that you selected when you set up Assured Open Source Software.

Update the project configuration file to point to the repository

Maven

Add the following settings to the appropriate section in the pom.xml file for your Maven project. Don't replace the authentication settings.

<project>
  <repositories>
    <repository>
      <id>artifact-registry</id>
      <url>artifactregistry://us-maven.pkg.dev/PROJECT_ID/assuredoss-java</url>
      <releases>
        <enabled>true</enabled>
      </releases>
      <snapshots>
        <enabled>false</enabled>
      </snapshots>
    </repository>
  </repositories>
</project>

Replace PROJECT_ID with the ID of the project that you selected when you set up Assured Open Source Software.

See the Maven POM reference for details about the structure of the file.

Gradle

Specify the following repository settings in your build.gradle file. Don't replace the authentication settings.

repositories {
  maven {
  url "artifactregistry://us-maven.pkg.dev/PROJECT_ID/assuredoss-java"
  }
}

Replace PROJECT_ID with the ID of the project that you selected when you set up Assured Open Source Software.

Update the project configuration file to add dependencies

To download an artifact as a part of your build, the artifact must be declared as a dependency.

Maven

Declare the packages that you want to download in the pom.xml file for your Maven project.

<dependency>
    <groupId>org.apache.logging.log4j</groupId>
    <artifactId>log4j-api</artifactId>
    <version>2.17.1</version>
</dependency>

Gradle

Declare the packages that you want to download in your build.gradle file.

dependencies {
    compile group: 'org.apache.logging.log4j', name: 'log4j-api', version: '2.17.1'
}
