Author Archives: Hubert Ikkink

My name is Hubert A. Klein Ikkink also known as mrhaki. I work at the great IT company JDriven. Here I work on projects with Groovy & Grails, Gradle and Spring. At JDriven we focus on SpringSource technologies. All colleagues want to learn new technologies, support craftmanship and are very eager to learn. This is truly a great environment to work in.

Gradle Goodness: Using and Working with Gradle Version

To get the current Gradle version we can use the gradleVersion property of the Gradle object. This returns a string value we can use for displaying the values. If we want to compare Gradle versions we can use the GradleVersion object. With this class we can get the current version, but we can also compare Gradle versions. This can be ...

Groovy Goodness: Closure as a Class

When we write Groovy code there is a big chance we also write some closures. If we are working with collections for example and use the each, collect or find methods we use closures as arguments for these methods. We can assign closures to variables and use the variable name to reference to closure. But we can also create a ...

In most of our projects we have dependencies on other code, like libraries or other projects. Gradle has a nice DSL to define dependencies. Dependencies are grouped in dependency configurations. These configuration can be created by ourselves or added via a plugin. Once we have defined our dependencies we get a nice overview of all dependencies in our project with ...

Since Groovy 2.3 we can easily create a fluent API for our classes with the @Builder AST transformation. We can apply the annotation to our classes and the resulting class file will have all the necessary methods to support a fluent API. We can customize how the fluent API is generated with different annotation parameters. In Groovy code we already ...

Groovy Goodness: Define Compilation Customizers With Builder Syntax

Since Groovy 2.1 we can use a nice builder syntax to define customizers for a CompileConfiguration instance. We must use the static withConfig method of the class CompilerCustomizationBuilder in the package org.codehaus.groovy.control.customizers.builder. We pass a closure with the code to define and register the customizers. For all the different customizers like ImportCustomizer, SecureASTCustomizers and ASTTransformationCustomizer there is a nice compact ...

Grails Goodness: Extending IntegrateWith Command

We can extend the integrate-with command in Grails to generate files for a custom IDE or build system. We must add a _Events.groovy file to our Grails projects and then write an implementation for the eventIntegrateWithStart event. Inside the event we must define a new closure with our code to generate files. The name of the closure must have the ...

Coloring Different Data Sources in IntelliJ IDEA

The database plugin in IntelliJ IDEA is a useful tool to work with data in databases. As long as we got a JDBC driver to connect to the database we can configure a data source. And then we can run queries, inspect the contents of tables and change data with the database tool window. It is not uncommon to have ...
