Oracle Developer Cloud Service – Use Maven Repository Artifacts in Build Jobs

Maven Repository

Oracle Developer Cloud Service (DevCs) includes a lot of great tools to help you build applications.  The Maven repository is useful for storing build dependencies and artifacts.

Maven artifacts can be uploaded to the repository after they are created by your build.  Dependencies can be manually uploaded ahead of time and pulled into the build jobs that need them.  Let’s take a look at how to work with dependency files in the Maven repository.

Upload Files

We’ll need to upload one or more files first.

  1. Click the Upload button.
  2. Drag and drop files into the box or click “select artifact files” and select the files.

My project uses Oracle JET version 4.1.0 so I’ll add it to my Maven repository.

Populate the file data.

  • GroupId: DinoDate
  • ArtifactId: oracleJet
  • Version 4.1.0
  • Packaging: zip

Click the Start Upload button.

Note: the file may be renamed in the repository.  For example, the oraclejet_4.1.0.zip file will be renamed to oraclejet-4.1.0.zip using the above data.

Now that we have a file in the repository let’s see use it in our build.

Use a Build Tool

If you’re using a build tool such as Maven or Gradle, you can get the dependency declaration for the Maven repository by clicking on the root of the project then copying it from the dependency declaration tab for your tool.

To get the file information:

  • Drill down into the folder.
  • Click on the file you need.
  • Copy the dependency declaration for the file.

At this point, you can run your build tool in a build job as normal.

But if you’re not using a build tool there is another way.

cURL

To use a tool such as cURL you need to get the URL for the file your after.

First, we’ll need the DevCs Maven repository URL for the project.

  1. Click /
  2. Copy URL from the dependency declaration panel

The repository URL will be similar to this:

Add file information to the URL:

This is the same data (plus the file name) we entered when we uploaded the file.

If you need to find the data for a file:

  • Drill down into the folder.
  • Click on the file you need.
  • Copy the information from the dependency declaration for the file.

Now fill out the rest of the URL:

Use cURL in the Build Job

The different components in DevCs already have the permissions to access each other in place so the build job can simply cURL from the Maven repository.

Add an “Execute Shell” build step and add the following (with your repository URL):

You can use any of the cURL features as you normally would, for example, to get multiple files in one call:

Why Store Dependencies in the Project?

Using the DevCs Maven Repository to store dependencies has many benefits, including:

  • It will be faster than pulling dependencies across the internet.
  • You won’t have to worry about a remote repository being offline or files being removed.
  •  Helps protect you from security problems if a remote repository is compromised.
