User's guide

Installation

PIE is deployed as a set of Maven artifacts to the MetaBorg artifact server, which you can consume with Maven or Gradle. To be able to get artifacts from the MetaBorg artifact servers, add the following to your build.gradle file:

repositories {
  jcenter()
  maven { url "https://artifacts.metaborg.org/content/repositories/releases/" }
  maven { url "https://artifacts.metaborg.org/content/repositories/snapshots/" }
}

or build.gradle.kts file:

repositories {
  jcenter()
  maven { url = uri("https://artifacts.metaborg.org/content/repositories/releases/") }
  maven { url = uri("https://artifacts.metaborg.org/content/repositories/snapshots/") }
}

or add the following to your Maven pom.xml file:

<repositories>
  <repository>
    <id>metaborg-release-repo</id>
    <url>https://artifacts.metaborg.org/content/repositories/releases/</url>
    <releases>
      <enabled>true</enabled>
    </releases>
    <snapshots>
      <enabled>false</enabled>
    </snapshots>
  </repository>
  <repository>
    <id>metaborg-snapshot-repo</id>
    <url>https://artifacts.metaborg.org/content/repositories/snapshots/</url>
    <releases>
      <enabled>false</enabled>
    </releases>
    <snapshots>
      <enabled>true</enabled>
    </snapshots>
  </repository>
</repositories>

To depend on version 0.6.0 of the runtime to build and execute pipelines, add the following Gradle dependency to your build.gradle file:

implementation 'org.metaborg:pie.runtime:0.6.0'

or build.gradle.kts file:

implementation("org.metaborg:pie.runtime:0.6.0")

or add the following to your Maven pom.xml file:

<dependency>
  <groupId>org.metaborg</groupId>
  <artifactId>pie.runtime</artifactId>
  <version>0.6.0</version>
</dependency>

The latest version is listed at the top of this file.

Components

PIE consists of several components:

  • pie.api: The PIE API for developing reusable interactive pipelines or incremental build scripts
  • pie.runtime: The PIE runtime for incrementally executing pipelines developed with the API
  • pie.taskdefs.guice: Guice dependency injection support for task definitions
  • pie.dagger: Dagger dependency injection support
  • task.java: Java compilation tasks
  • task.archive: ZIP/Jar archiving and unarchiving tasks

Development

This section details the development of this project.

Building

The master branch of this repository can be built in isolation. However, the develop branch must be built via the devenv repository, due to it depending on development versions of other projects.

This repository is built with Gradle, which requires a JDK of at least version 8 to be installed. Higher versions may work depending on which version of Gradle is used.

To build this repository, run ./gradlew buildAll on Linux and macOS, or gradlew buildAll on Windows.

Automated Builds

This repository is built on:

Publishing

This repository is published via Gradle and Git with the Gitonium and Gradle Config plugins. It is published to our artifact server in the releases repository.

First update CHANGELOG.md with your changes, create a new release entry, and update the release links at the bottom of the file.

Then, commit your changes and merge them from the develop branch into the master branch, and ensure that you depend on only released versions of other projects (i.e., no SNAPSHOT or development versions). All dependencies are managed in the core/depconstraints/build.gradle.kts file.

To make a new release, create a tag in the form of release-* where * is the version of the release you'd like to make. Then first build the project with ./gradlew buildAll to check if building succeeds.

If you want our buildfarm to publish this release, just push the tag you just made, and our buildfarm will build the repository and publish the release.

If you want to publish this release locally, you will need an account with write access to our artifact server, and tell Gradle about this account. Create the ~/.gradle/gradle.properties file if it does not exist. Add the following lines to it, replacing <username> and <password> with those of your artifact server account:

publish.repository.metaborg.artifacts.username=<username>
publish.repository.metaborg.artifacts.password=<password>

Then run ./gradlew publishAll to publish all built artifacts. You should also push the release tag you made such that this release is reproducible by others.
