Re: Re: making the most of Groovy in Action 2nd edition
Thanks Paul and Erik!
My needs are to browse the code examples and run them to improve my
understanding. So I rather download the Groovy 2.4 or use
http://groovyconsole.appspot.com
My groovy experience so far is writing medium-difficulty declarative
pipelines for Jenkins. After seeing some peer inspirations how to write
shell scripts with groovy I decided to invest some time.
Hope this clears what I want to achieve.

Re: Re: making the most of Groovy in Action 2nd edition
Not sure if this is the best way to do this, but I wrap antbuilder in my own
class so that I can get ant event messages to my logger
package script.ant
import groovy.ant.AntBuilder as AB
import org.apache.tools.ant.BuildEvent
import org.apache.tools.ant.BuildLogger
@groovy.util.logging.Slf4j
class AntBuilder {
static AB newInstance () {
AB ab = new AB()
ab.project.buildListeners.each { ab.project.removeBuildListener(it) }
ab.antProject.addBuildListener(new BuildLogger() {
@Override public void buildStarted (BuildEvent event) { }
@Override public void buildFinished (BuildEvent event) { }
@Override public void targetStarted (BuildEvent event) { }
@Override public void targetFinished (BuildEvent event) { }
@Override public void taskStarted (BuildEvent event) { }
@Override public void taskFinished (BuildEvent event) { }
@Override public void messageLogged (BuildEvent event) {
if (event?.task) log.info("[{}] {}",
event.task.taskName, event.message)
}
@Override public void setMessageOutputLevel (int level) { }
@Override public void setOutputPrintStream (PrintStream
output) { }
@Override public void setEmacsMode (boolean emacsMode) { }
@Override public void setErrorPrintStream (PrintStream err)
{ }
})
ab
}
}

Hi Dimitar,
From Groovy 4, Groovy's "module" jars are fully-compliant with the
JPMS rule disallowing split packages. The Groovy 3 and 4 release notes
have more details.
But basically, for the example you are showing, AntBuilder is now in
the groovy.ant package, so if you add the appropriate import, you'll
be good to go. AntBuilder was in the groovy.util package in earlier
Groovy versions, and so didn't need the import. Mind you, there will
likely be numerous places where such changes are needed.
We haven't produced an updated version of those examples for Groovy 4.
Cheers, Paul.
