Uploading/Downloading Components on the Self-Hosted Repo Page

Uploading Components

1. Click a project card to access the project. (If no project is available, create one.)
2. Choose Artifact > Self-hosted Repos from the navigation pane.
3. In the left pane, click the target repository to which the private component is to be uploaded.
4. Click Upload on the right of the page.
5. In the Upload dialog box, specify parameters, select the file, and click Upload. Detailed configuration for each component type is described below.
   

   • The maximum file size for uploads is 100 MB for Maven, npm, PyPI, RPM, and Debian types, and 20 MB for NuGet.
   • You are advised not to upload files containing sensitive information such as plaintext accounts and passwords to self-hosted repos.

Maven Components

• Project Object Model (POM) is the basic working unit of a Maven project. It is an XML file that contains basic project information to describe how to build a project and declare project dependencies. When a build task is run, Maven searches for the POM in the current directory, reads its content, obtains the required configuration information, and builds the target component.
• Maven coordinates: X, Y, and Z are used to uniquely identify a point in the three-dimensional space. In Maven, GAV is used to identify a unique component package. It stands for Group ID, Artifact ID, and Version. Group ID indicates a company or organization. For example, Maven core components are in the org.apache.maven organization. Artifact ID indicates the name of the component package. Version indicates the version of the component package.
• Maven dependencies are crucial for POM files. The building and running of most projects depend on the dependency on other components. Add the dependency list to your POM file. If the App component depends on the App-Core and App-Data components, the configuration is as follows:

  <project xmlns="http://maven.apache.org/POM/4.0.0"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:schemaLocation="http://maven.apache.org/POM/4.0.0
     http://maven.apache.org/xsd/maven-4.0.0.xsd">
        <modelVersion>4.0.0</modelVersion>
        <groupId>com.companyname.groupname</groupId>
        <artifactId>App</artifactId>
        <version>1.0</version>
        <packaging>jar</packaging>
        <dependencies>
           <dependency>
              <groupId>com.companyname.groupname</groupId>
              <artifactId>App-Core</artifactId>
              <version>1.0</version>
           </dependency>
        </dependencies>  
        <dependencies>
           <dependency>
              <groupId>com.companyname.groupname</groupId>
              <artifactId>App-Data</artifactId>
              <version>1.0</version>
           </dependency>
        </dependencies>  
  </project>

Uploading a Maven Component

POM and GAV upload modes are supported.

• POM

  In POM mode, you can either upload just the POM file or both the POM file and its related components. The uploaded file must match the artifactId and version values specified in the POM. As shown in the following figure, if the artifactId value is demo and the version value is 1.0 in the POM, then the uploaded file must be named demo-1.0.jar.

  Figure 1 Uploading a component in POM mode
  

  The POM file structure is as follows:

  <project>
    <modelVersion>4.0.0</modelVersion>
    <groupId>demo</groupId>
    <artifactId>demo</artifactId>
    <version>1.0</version>
  </project>

  

  The modelVersion tag must exist and the value must be 4.0.0, indicating that Maven2 is used.

  If you upload files in both the POM and File area, the artifactId and version values in POM must match the file name in File. For example, if the artifactId value is demo and the version value is 1.0 in POM, then the uploaded file must be named demo-1.0 in File.

• GAV

  In the GAV mode, the Group ID, Artifact ID, and Version parameters must be manually specified and they determine the name of the file to upload. Extension indicates the packaging type and determines the file type to be uploaded.

  Classifier is used to differentiate artifacts that are built from the same POM but contain different contents. This field is optional. It can contain letters, digits, underscores (_), hyphens (-), and dots (.). If you specify this field, it will be appended to the file name.

  Common Usage Scenario

  • Differentiate versions by name, such as demo-1.0-jdk13.jar and demo-1.0-jdk15.jar.
  • Differentiate usage by name, such as demo-1.0-javadoc.jar and demo-1.0-sources.jar.

npm Components

Node Package Manager (npm) is a JavaScript package management tool. An npm component package is the item managed by npm, and the npm repository is used to store and manage these packages.

The npm component package consists of a structure and file description.

• Package structure: organizes various files in a package, such as source code files and resource files.
• Description file: describes package information. Example: package.json, bin, and lib files

The package.json file in the package is a description file of a project or module package. It contains information such as the name, description, version, and author. The npm install command downloads all dependent modules based on this file.

An example of the package.json file is as follows:

{
  "name": "third_use",			//Package name
  "version": "0.0.1",           //Version number
"description": "this is a test project", // Description
  "main": "index.js",			//Entry file
  "scripts": {					//Script command
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "keywords": [					//Keyword
    "show"
  ],
  "author": "f",				//Developer name
  "license": "ISC",				//License agreement
  "dependencies": {				//Project production dependencies
    "jquery": "^3.6.0",
    "mysql": "^2.18.1"
  },
  "devDependencies": {			//Project development dependencies
    "less": "^4.1.2",
    "sass": "^1.45.0"
  }
}

The name and version are the most important fields and must exist. Otherwise, the current package cannot be installed. The two attributes together form the unique identifier of an npm package.

name indicates the name of the package. The first part of the name, such as @scope, is used as the namespace. The other part is name. Generally, you can search with the name field to install and use the required package.

{
  "name": "@scope/name"
}

version indicates the version of the package, which is in the x.y.z format.

{
  "version": "1.0.0"
}

Uploading an npm Component

npm component packages in .tgz format can be uploaded to self-hosted repos. When uploading packages, you need to set the following parameters.

When uploading a component, ensure that the PackageName starts with a path in the path list added during repository creation. For details, see Configuring a Repository in the help guide.

Example:

The path @test is added when you create an npm repository.

When uploading components to the repository, make sure that the PackageName starts with @test. If a path outside the path list is used, for example, @npm, the upload will fail.

After the upload is successful, you can find the component in .tgz format in the repository list and the corresponding metadata is generated in the .npm directory.

Uploading a Go Component

Go, also known as Golang, is a programming language developed by Google. Golang 1.11 and later support modular package management. A module is a unit for source code exchange and versioning in Go. A MOD file identifies and manages a module. A ZIP file is a source code package. There are two types of Go modules: v2.0 and later and v2.0 and earlier. The management of the Go module is different between these two versions.

To upload a Go component, you need to upload both a ZIP file and a MOD file and set the following parameters.

Uploading a PyPI Component

You are advised to go to the project directory (which must contain the setup.py configuration file) and run the following command to compress the components to be uploaded into a wheel (.whl) installation package. By default, this package is generated in the dist directory of your project directory. Note that the Python package management tool pip supports only wheel installation packages.

python setup.py sdist bdist_wheel

You need to set the following parameters.

After the upload is successful, you can find the installation package in .whl format in the repository list. In addition, the corresponding metadata is generated in the .pypi directory, which can be used for pip installation.

Uploading an RPM Component

Introduction to RPM

• Red Hat Package Manager (RPM), developed by Red Hat, is used by many Linux distributions. It is a software management system that installs software on Linux in database recording mode.
• You are advised to package and name the RPM binary file according to the following rules:

Software name-Main version number of the software.Minor version number of the software.Software revision number-Number of software compilation times.Hardware platform suitable for the software.rpm

For example, hello-0.17.2-54.x86_64.rpm. hello is the software name, 0 is the major version number of the software, 17 is the minor version number, 2 is the revision number, 54 is the number of times that the software is compiled, and x86_64 is the hardware platform suitable for the software.

Note: You need to set the following parameters when uploading components.

1. Go to the self-hosted repo page. In the left pane, click the target repository to which the private component is to be uploaded.
2. Click Upload on the right of the page.
3. Set the component parameters, select the file, and click Upload.

   After the upload is successful, you can find the RPM binary package in the repository list and the corresponding metadata repodata directory is generated in the component name directory. You can use Yum to install the component.

Uploading a Debian Component

When uploading a Debian component, you need to set the following parameters:

After the upload is successful, you can find the installation package in .deb format in the repository list. In addition, the corresponding metadata is generated in the dists directory, which can be used for Debian installation.

Uploading a NuGet Component

A NuGet package is a single ZIP file with a .nupkg extension. As a shareable unit of code, developers can publish it to a dedicated server to share it with other team members.

CodeArts Artifact creates a NuGet repository to host and manage NuGet packages.

• You are advised to package and name the NuGet file according to the following rules:

  Software name-Major version number of the software.nupkg

  Example: automapper.12.0.0.nupkg

1. Go to the self-hosted repo page. In the left pane, click the target NuGet repository to which the private component is to be uploaded.
2. Click Upload, select the NuGet file to be uploaded from the local host, and click Upload.

   

3. View components that are successfully uploaded in the repository list.

   

   metadata stores metadata and is named after the component name. metadata cannot be deleted manually. It will be deleted or added automatically when the corresponding component is deleted or restored.

   package stores components.
