ysb33r / SumSquaresNumbersDiv7SmallerThan100.groovy
Created Apr 15, 2013
Russel Winder did a lightning talk at ACCU 2013 titled "Who needs C++ when you have D and Go": http://www.slideshare.net/Russel_Winder/who-needscwhenyouhaved-andgo I decided to address the same problem using a one-liner in Groovy
View SumSquaresNumbersDiv7SmallerThan100.groovy
println ((0..<100).step(7).collect{it*it}.sum())

I am trying to wrapper a Task class in Gradle to wrap some legacy build tools i.e. GNU Make, SCons etc. This is to help migrating legacy builds to Gradle. The idea is to still call parts of the old build systems and just to collect the artifacts from them. So instead of inheriting from DefaultTask I thought it would be easier to just to extend s…

ysb33r / XsltUnitToJUnitXml.xsl
Last active Dec 18, 2015
I do not know if anyone still uses for XSLTUnit (http://xsltunit.org/) for new development, but I recently had the requirement to convert the XML created by this framework to a JUnit XML format so that it can be read by other tools such as JUnit that understands this format.

ysb33r / RelativePath.groovy
Last active Nov 29, 2020
The Groovy way to obtain a relative path given two paths.
View RelativePath.groovy
def root= new File('/usr/share')
def full= new File('/usr/share/docs/rpm-4.4')
// Print the relative path of 'full' in relation to 'root'
// Notice that the full path is passed as a parameter to the root.
def relPath= new File( root.toURI().relativize( full.toURI() ).toString() )

ysb33r / Download+Unpack.groovy
Created Jun 19, 2013
groovy-vfs makes downloading & unpacking very simple. The following works well for smaller archives. Once the archive contains thousands of files, it is better to download first and then unpack. (This is due to a performance issue inside VFS2, not groovy-vfs).
View Download+Unpack.groovy
@Grapes([
@GrabResolver( name='grysb33r', root='http://dl.bintray.com/ysb33r/grysb33r' ),

@Grab( 'commons-httpclient:commons-httpclient:3.1')

import org.ysb33r.groovy.dsl.vfs.VFS
// This will download the compressed archive from Sourceforge and unpack it to a local directory

If you are working with Jenkins BuildFlow plugin you can get some useful information of the returned build() call.
View JenkinsBuildFlowObjects.groovy
// Given that you have kicked off a build according to the DSL syntax
def results = build('RUN_THIS_JOB')
// Get out the name of the job again
println results.name
// Get the build ID
println results.id
// Get the build URL
