Powerful feature in Gretty 0.0.24 – full support of Spring Boot 1.1.0

Today is a wonderful day: Spring Boot 1.1.0 was released and I released Gretty version 0.0.24.

Gretty is a feature-rich gradle plugin for running web-apps on Jetty. It supports multiple Jetty versions (7, 8 and 9), multiple web-apps and many more. It wraps Jetty functions as convenient Gradle tasks and configuration DSL. A complete list of Gretty features is available in feature overview.

There is new powerful feature in Gretty 0.0.24: it supports running Spring Boot web-apps out-of-the-box. All Gretty features, including (but not limited to) debugging, code coverage and integration tests, also apply to spring-boot web-apps.

Simplest Gretty setup with Spring Boot:

You get Gretty as maven artifacts at jcenter and maven central under the group “org.akhikhl.gretty”.

Full Gretty sources and examples are available at https://github.com/akhikhl/gretty

Full Gretty documentation is available at http://akhikhl.github.io/gretty-doc/

 

Killer feature in Gretty version 0.0.18 – multiple web-apps support

Let’s assume, you are developing web-applications with JVM-based languages and technologies and are looking for the solution of the following problem:

You have a bunch of web-apps, that must run all at the same time, because they call each other. You also want to debug multiple web-apps and even run integration tests – on the complete bunch.

Here is the solution to this problem: use Gretty. This is gradle plugin, capable of exactly this: running multiple web-apps, debugging, integration tests. Of course, it is open-source and available at jcenter and maven central.

Gretty can start arbitrary number of web-apps of various types: gradle projects, WAR-files in the file system and even WAR-files from maven dependencies.
Multiple web-apps feature works out-of-the-box in configureless mode, although it is fully configurable/customizable.

The central concept of Multiple web-apps feature is farm – a collection of web-apps, that should run together.

There are two ways to define and use farms:

  • Default farm is automatically created for you by Gretty. You may add artbitrary web-apps to it and then invoke farm-specific tasks: farmRun, farmRunDebug, etc. Note that farm-specific tasks are not using gretty tasks (jettyRun, jettyRunDebug, etc.), but they understand and use gretty configurations.
  • Named farms, which you create yourself in gradle script. You can add as many named farms as you want, and you can add web-apps to farms in arbitrary constellations. Each named farm provides a specific set of farm tasks. For example, if you define farm with name “XYZ”, there will be new tasks farmRunXYZ, farmRunDebugXYZ, etc. available.

You can start using multiple web-apps support right away, using the following scenario as a starting point:

Create three empty folders: ProjectA, ProjectB and ProjectC, so that folder tree looks like this:

ProjectA
|-- ProjectB
\-- ProjectC

Create file “ProjectA/settings.gradle”, insert code:

include 'ProjectA', 'ProjectB'

Explanation: we organize multi-project setup, so that multiple web-apps can be started/stopped by gretty-farm plugin.

Create file “ProjectA/build.gradle”, insert code:

buildscript {
  repositories {
    jcenter()
  }

  dependencies {
    classpath 'org.akhikhl.gretty:gretty-plugin:+'
  }
}

apply plugin: 'gretty-farm'

Create file “ProjectA/ProjectB/build.gradle”, insert code:

apply plugin: 'gretty'

Create file “ProjectA/ProjectC/build.gradle”, insert code:

apply plugin: 'gretty'

Done! Now you can run multiple web-apps by running the following command in ProjectA:

gradle farmRun

Expected output:

Jetty server 9.1.0.v20131115 started.
:ProjectB runs at the address http://localhost:8080/ProjectB
:ProjectC runs at the address http://localhost:8080/ProjectC
servicePort: 9900, statusPort: 9901
Press any key to stop the jetty server.

Of course, you’ll get 404 in the browser, because web-apps don’t contain any pages. But, as soon as you add pages or/and servlets to the web-apps, things will get real.

By default farm automatically adds all subprojects of the farm project, which are facilitated with gretty plugin, to web-apps list. You can also explicitly add web-apps to the given farm.

Gretty-farm plugin defines new, distinct set of tasks for running farms: farmRun, farmRunDebug, farmRunWar, farmRunWarDebug, etc.

GVM – tool for managing groovy/gradle versions

Just discovered GVM – Groovy enVironment Manager ( http://gvmtool.net/ )
First impression: it’s like apt-get, but for groovy-based frameworks. Second impression: support of multiple versions is very useful thing.
Will use it at home and in office to automate installation of groovy-related stuff.

Gretty Plugin is now on Maven Central

I published Gretty Plugin to maven central, coordinates: org.akhikhl.gretty:gretty-plugin:0.0.4.
Project home: https://github.com/akhikhl/gretty
scm: https://github.com/akhikhl/gretty.git, git@github.com:akhikhl/gretty.git

Gretty Plugin is actually gradle plugin for running web-applications under jetty 8.1.8 and servlet API 3.0.1.

gradle snippet: sources and javadoc jar for every subproject of given project

gradle snippet: sources and javadoc jar for every subproject of given project

Add this to the parent “build.gradle” to enable xyz-sources.jar and xyz-javadoc.jar generation for every java and groovy subproject of the given parent project. The script tolerates non-java subprojects.
