# Speed up Builds with Nexus

# Push JAR Package to Private Server

# Upload Maven settings.xml to the Platform

Go to My Application > Select Application > Settings > Pipelines > Variable Configuration > Select Environment.

Click Add Variable, select the type as File and enable encryption, then upload settings.xml and define the variable name as MAVEN_SETTING_FILE.

Warning

Encryption is required as the file includes sensitive information such as passwords.
To avoid XXE attacks, the platform prohibits uploading XML files. XML files can be changed to settings_xml files (Linux system does not distinguish file types).

An example of settings.xml is as follows:

<?xml version="1.0" encoding="UTF-8"?>

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">

  <servers>
    <server>
      <id>terminus</id>
      <username>deployment</username>
      <password>******</password>
    </server>
  </servers>
</settings>

# Configure Push Address of pom.xml

Add the following configuration to pom of the corresponding project, otherwise it cannot be pushed.

<distributionManagement>
    <repository>
        <id>terminus</id>    <!-- server.id configured in settings.xml -->
        <name>Releases</name>
        <url>http://private server address/repository/releases</url>  <!-- release private server address -->
    </repository>
    <snapshotRepository>
        <id>terminus</id>
        <name>Snapshots</name>
        <url>http://private server address/repository/releases</url>  <!-- snapshot private server address -->
    </snapshotRepository>
</distributionManagement>

# Configure Pipeline to Upload JAR Package

MAVEN_SETTING_FILE is the variable name configured above.

version: "1.1"

stages:
- stage:
  - git-checkout:
      alias: git-checkout
      params:
        depth: 1
- stage:
  - java-build:
      alias: java-build
      version: "1.0"
      params:
        build_cmd:
           - "rm -rf /usr/share/maven/conf/setting.xml"
           - "mvn clean deploy  -e -B -U --settings ((MAVEN_SETTING_FILE)) -Dmaven.test.skip"
        jdk_version: 8
        workdir: ${git-checkout}

Add configuration of continuous integration (CI) if automated building is required.

on:
  push:
    branches:
      - develop # Continuous integration

Tips

401 in Maven indicates incorrect password.

405 in Maven possibly indicates incorrect private server address, as some private server addresses cannot be pushed, such as public.

# Push JAR Package to Private Server (Gradle)

# Configure Password of Nexus Private Server

Go to My Application > Select Application > Settings > Pipelines > Variable Configuration > Select Environment.

Click Add Variable, select the type as Value and enable encryption, then configure the following variables:

NEXUS_USERNAME
NEXUS_PASSWORD

Warning

Encryption is required as the file includes sensitive information such as passwords.

# Configure Push Address of build.gradle

Add the following configuration to build.gradle of the corresponding project, otherwise it cannot be pushed. For more information, see Configuration of build.gradle (opens new window).
