WarpFleet Gradle Plugin

Discover the WarpFleet Gradle plugin that allows you to interact with WarpFleet and generate macros documentation

We have launched a brand new tool to interact with WarpFleet.

You already know (I hope so) the WarpFleet Cli that relies on NodeJS. We decided to refactor it as a Gradle plugin that only relies on Java.

For now, both tools are working and supported.

WarpFleet is the Warp 10 artifact repository. Read more about it here.

Prerequisites

You need:

Java >= 1.8 (18 supported)
Gradle

That's all.

Setup

Create a directory and init a Gradle project:

$ mkdir my-warpfleet-project
$ cd my-warpfleet-project
$ gradle init

Select type of project to generate:
  1: basic
  2: application
  3: library
  4: Gradle plugin
Enter selection (default: basic) [1..4] 1

Select build script DSL:
  1: Groovy
  2: Kotlin
Enter selection (default: Groovy) [1..2] 1

Project name (default: my-warpfleet-project):

BUILD SUCCESSFUL in 6s
2 actionable tasks: 2 executed

Now edit the build.gradle file (which should be empty):

buildscript{
  repositories {
      mavenCentral()
      mavenLocal() 
      dependencies{
        classpath 'io.warp10:warpfleet-gradle-plugin:0.0.3'
      }
  }  
}

apply plugin: 'io.warp10.warpfleet-gradle-plugin'

You should now be able to invoke new Gradle tasks:

$ ./gradlew -q tasks --group WarpFleet

To see all tasks and more detail, run gradlew tasks --all

To see more detail about a task, run gradlew help --task <task>

Browsing the WarpFleet Repository

The WarpFleet repository is organized like a Maven repository. We expose artifacts as jar files.

These jars contain either:

extensions (new functions added to the WarpScript language)
plugins (new features added to the Warp 10 platform)

They are defined by a group (e.g. io.warp10), an artifact name (e.g. warp10-ext-s3 or warp10-plugin-kafka), a version number (e.g. 1.2.3), and an optional classifier.

So, you can define an artifact with a selector like this:

group:artifact's name:version:classifier

Browse available plugins and extensions

You can use the Gradle plugin to browse our repositories.

wfGetGroups – Get the list of available groups:

$ ./gradlew -q wfGetGroups 
- io.senx
- io.warp10
...

wfGetArtifacts – Get the list of available artifacts:

$ ./gradlew -q wfGetArtifacts --group=io.warp10
- io.warp10:warp10-ext-arrow:2.0.3-uberjar (Conversions to and from Apache Arrow streaming format)
- io.warp10:warp10-ext-barcode:1.0.2-uberjar (WarpScript™ Barcode Extension)
- io.warp10:warp10-ext-flows:0.1.1-uberjar (FLoWS WarpScript Extension)
- io.warp10:warp10-ext-forecasting:2.0.0 (Forecast extension)
- io.warp10:warp10-ext-geotransform:0.2.3-uberjar (Extension to transform coordinates from one geographic coordinate system to another. Based on Proj4J.)
- io.warp10:warp10-ext-git:1.0.1-uberjar (WarpScript Git Extension)
...

wfGetVersions – Get the list of available artifact versions:

$ ./gradlew -q wfGetVersions --group=io.warp10 --artifact=warp10-plugin-warpstudio
- Name:            io.warp10:warp10-plugin-warpstudio
- Description:     WarpStudio, the WarpScript editor
- Latest version:  2.0.6
- Available:
    - 2.0.6
    - 2.0.5
    - 2.0.4
    - 2.0.3
    - 2.0.2

Warp 10 Extension/Plugin Installation

You can use this Gradle plugin to add new features and functionality to your Warp 10 platform.

Single Artifact Installation

$ ./gradlew -q wfInstall \
    --group=io.warp10 \
    --artifact=warp10-plugin-warpstudio \
    --vers=2.0.3 \
    --dest=/path/to/warp10

The vers field is not mandatory and can be set to latest. In either case, WarpFleet will fetch the latest available version.

You can also use this syntax:

$ ./gradlew -q wfInstall \
    --packages=io.warp10:warp10-plugin-warpstudio:2.0.3:jar \
    --dest=/path/to/warp10

Multiple Artifacts Installation

Install many plugins and extensions at once with a comma-separated list of artifact selectors:

$ ./gradlew -q wfInstall \
    --packages=io.warp10:warp10-plugin-warpstudio:latest,io.warp10:warp10-ext-barcode \
    --dest=/path/to/warp10

Generate Documentation

Maybe you have developed macros that are deployed on your Warp 10 platform and you would like to generate documentation about them? No problem, this Gradle plugin can actually parse the INFO structure of your macros and generate documentation in various formats:

default: json
json: JSON files
md or markdown: Markdown files with an index
html: HTML pages with an index.

For instance for @path/to/macro and /path/to/root/folder/path/to/macro.mc2

$ ./gradlew -q wfDoc \
        --url=https://warp10.server/api/v0/exec \ 
        --source=/path/to/root/folder \  # where your Warpscripts are located  
        --dest=./doc \                   # documentation destination
        --macroDir=path \                # root path of your macros
        --format=json                    # json by default (could be html or md)

Artifact publication

You may have authored a Warp 10 plugin or a WarpScript extension and would like to share it with the rest of the Warp 10 community? Follow the steps below:

First Step: Contact SenX

You can also send an email with your GPG key attached.

Second Step: Publish it

Once your GPG key has been accepted and installed on our servers, you can publish your extension/plugin:

$ ./gradlew -q wfPublish \
        --gpgKeyId=BDxxx0A \        # Optional GPG Key Id
        --vers=1.2.3                # Optional version overrides version in wf.json
        --wfJson=/path/to/wf.json   # where wf.json is located

Build.gradle

Yes, you do not have to use the command line to pass all your parameters, you can benefit from your build.gradle (the one described at the top of this article).

Documentation sample

apply plugin: 'io.warp10.warpfleet-gradle-plugin'
 
buildscript{
  repositories {
      mavenCentral()
      mavenLocal() 
      dependencies{
        classpath 'io.warp10:warpfleet-gradle-plugin:0.0.3'
      }
  }  
}

warpfleet {
    url = "https://warp10.server/api/v0/exec" 
    source = "/path/to/root/folder" 
    dest = "./doc" 
    macroDir = "path"
    format = "html"
}

And just run:

$ ./gradlew -q wfDoc

Artifact publication sample

Of course, the same applies to artifact publication. Just edit the build.gradle file of your extension (or plugin) by adding this:

apply plugin: 'io.warp10.warpfleet-gradle-plugin'
 
buildscript{
  repositories {
      mavenCentral()
      mavenLocal() 
      dependencies{
        classpath 'io.warp10:warpfleet-gradle-plugin:0.0.3'
      }
  }  
}

..... // rest of your file

warpfleet {
    gpgKeyId = "BDxxxxx0A" 
    vers = "1.2.3" 
    wfJson = "./wf.json" 
}

And just run:

$ ./gradlew build shadowJar wfPublish
