Filtering Source Files using the Templating Maven Plugin

Tue, 03 Sep 2013 00:00:00 +0200

The Templating Maven Plugin looks useful if one needs to copy and to filter source files in a project e.g. to add property values from the build environment to a class.

For a short demonstration I’ve added the following short snippet.

Dependencies

Only one dependency needed .. simply add the following snippet to your pom.xml

<build>
  <plugins>
    <plugin>
      <groupId>org.codehaus.mojo</groupId>
      <artifactId>templating-maven-plugin</artifactId>
      <version>1.0-alpha-3</version>
      <executions>
        <execution>
          <id>filter-src</id>
          <goals>
            <goal>filter-sources</goal>
          </goals>
        </execution>
      </executions>
    </plugin>
  </plugins>
</build>

It’s been a long way for Java FX from the days of the F3 project the current release 2.2. Today there are many options how to create a Java FX application .. you may be using Java, Scala, Groovy or Visage, you may create your application in a programmatic way using the comfortable integrated builders or you may create your views using XML layouts and easy data-bindings with a few annotations.

New Plugin released: Quick Subtasks for JIRA

Tue, 21 Aug 2012 00:00:00 +0200

Recently after a long sprint planning meeting I had the pleasure to spend some time writing down the results of the team’s task breakdown in JIRA.

In our process, each user story is documented as a JIRA issue and each task from the breakdown is saved as a subtask for the parent issue.

Because I am too lazy in this situation I wrote the following plugin that allowed me to quickly create multiple subtasks for a selected JIRA issue.

Creating a Windows Executable from a Jar using Maven

Tue, 07 Aug 2012 00:00:00 +0200

Often in the life of a developer there is the need to create a windows executable for a Java application that is build and packaged in a Jar file.

The following short example shows how to create an executable Jar first and a windows executable containing vendor information, a nice icon and other stuff afterwards by using a combination of the Maven Shade Plugin and the launch4j Plugin for Maven.

Integrating Groovy in your Maven builds using GMaven

Tue, 12 Jul 2011 00:00:00 +0200

Often ant tasks are used in Maven builds but wouldn’t it be more attractive to integrate the Groovy language into our build process?

GMaven is the answers to this problem and brings together Maven and Groovy. It allows us to execute Groovy scripts inline from our Maven configuration, from a local script or even from a remote location. In the following short examples I am going to show how to configure Maven to execute Groovy scripts from different locations.

You’re using the popular Confluence wiki? You’re using its RPC/SOAP API and missing a function you really need? Just extend the capabilities of the Confluence RPC API by programming a custom web service component – it is really easy and also well documented.

In this tutorial we’re going to take a look on how to quickly implement a SOAP service, securing it and putting its methods in a transactional context.

Prerequisites

Maven >=2
JDK >= 5
Confluence Wiki >= 3.0 (for a quick installation guide take a look at this article)
SoapUI for Testing

How to create a Template Bundle Plugin in Confluence

Mon, 12 Jul 2010 00:00:00 +0200

Since Confluence 3.2. there is a new plugin module type that allows you to deploy templates in a bundle via the plugin API.

In addition it is possible to assign these templates to specific spaces and preview available templates in the Confluence administration area.

So let’s build some sample templates..

Creating a Template Bundle Plugin

Creating a template bundle is easy – just create a class implementing TemplatePackage – there are two methods: one returns a list of bundled PageTemplate Objects the other the name for the template bundle.

Extending the Confluence Search Index

Sun, 23 May 2010 00:00:00 +0200

Developing plugins for the Confluence Wiki a developer sometimes needs to save additional metadata to a page object using Bandana or the ContentPropertyManager. Wouldn’t it be nice if this metadata was available in the built-in Lucene index?

That is were the Confluence Extractor Module comes into play..

Overview

An extractor allows the developer to add new fields to the lucene search index. Creating a new extractor is quite simple – just implement the interface com.atlassian.bonnie.search.Extractor or bucket.search.lucene.extractor.BaseAttachmentContentExtractor if you want to build a new file extractor.

Snippets: Getting License Information from the Confluence API

Thu, 06 May 2010 00:00:00 +0200

Sometimes one needs to look up license details of a running Confluence system .. perhaps for creating a commercial plugin or to display recommendations dependant from the license used. For this reason there are a few possibilities for receiving some license information from the Confluence API or the velocity context.

Note: This article is outdated since the Atlassian Marketplace was launched and a shiny new licensing API was added. Until this article is updated I strongly recommend to take a closer look at the detailed information that Atlassian is providing in the Developer Documentation.

Manage dependencies with the Maven Dependency Plugin

Sun, 04 Apr 2010 00:00:00 +0200

In a maven project there are lots of dependencies to handle – often one wants to know which version of a software comes from.

The solution to this problem is the Maven Dependency Plugin which helps you to find used/unused/declared/undeclared dependencies in your project.

In addition the plugin allows you to copy or unpack artifacts.

Maven Goals

dependency:copy – copies artifacts defined in the config to a specified location – details available here
dependency:resolve – resolves all dependencies and shows the versions
dependency:go-offline – resolves everything the project needs like dependencies, plugins and reports
dependency:analyze - parses the dependencies and shows if they are used/declared/unused/undeclared ..
dependency:analyze-dep-gmt - finds mismatches between resolved dependencies and those listed in the dependencyManagement section
dependency:tree – shows a nice dependency tree for the maven project

Linux Snippets

Mon, 01 Mar 2010 00:00:00 +0100

These are not only linux snippets but also bash snippets and snippets using tools that run under Linux, *nix or sometimes even MacOSX, I should reorder this article someday ;)

Settings for more reliable bash scripts

set -euo pipefail

this gives us …

-e: exit script if a single command fails
-u: exit script if an unset variable is used
-o pipefail: return value of a pipeline is the status of the last command to exit with a non-zero status, or zero if no command exited with a non-zero status

Maven Snippets

Mon, 01 Mar 2010 00:00:00 +0100

Extract Coordinates from the POM

Helpful for build and integration environments, pipelines etc.

Exctract the Project version from the pom.xml

mvn org.apache.maven.plugins:maven-help-plugin:3.1.0:evaluate -Dexpression=project.version -q -DforceStdout

Override a Property via local configuration

e.g. to override the property xxx from your project’s pom.xml

Create a directory .mvn in your project directory root
Create a file named maven.config in this directory
Insert -Dxxx=newvalue into the file to override this property

Don’t forget to add .mvn to your .gitignore!

Vim Snippets

Vim Plugin Manager

Installation

Download it from its GitHub repository or the risky but easy way using curl:

curl -fLo ~/.vim/autoload/plug.vim --create-dirs https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim

Adding Plugins

Add a plugin section to the .vimrc:

.vimrc

call plug#begin()
" The default plugin directory will be as follows:
"   - Vim (Linux/macOS): '~/.vim/plugged'
"   - Vim (Windows): '~/vimfiles/plugged'
"   - Neovim (Linux/macOS/Windows): stdpath('data') . '/plugged'
" You can specify a custom plugin directory by passing it as the argument
"   - e.g. `call plug#begin('~/.vim/plugged')`
"   - Avoid using standard Vim directory names like 'plugin'

" Make sure you use single quotes

" Gruvbox Theme
Plug 'sainnhe/gruvbox-material'

" Initialize plugin system
" - Automatically executes `filetype plugin indent on` and `syntax enable`.
call plug#end()
" You can revert the settings after the call like so:
"   filetype indent off   " Disable file-type-specific indentation
"   syntax off            " Disable syntax highlighting
