Gretty 1.2.3 is out!
May 18, 2015Posted by on
I’m happy to announce that Gretty version 1.2.3 is out!
What’s new: I finally fixed bugs with classpath isolation. Now all web-applications (including SpringBoot applications) run on their classloader and are isolated from one another. That means: no more spring beans conflicts, no more problems configuring logback.
You don’t know what is Gretty? It’s a Gradle plugin for running web-applications on Tomcat and Jetty. Full documentation and sources: https://github.com/akhikhl/gretty
Concurrent Kitties Using GPars
May 18, 2015Posted by on
Stuff I've learned recently...
On today’s Groovy Podcast, I mentioned that I was teaching a Groovy training class this week at Research Now in Plano, TX. That’s not how I said it, though. I said that I was broadcasting live in front of a studio audience and that they were the most amazingly awesome group I’ve ever encountered.
(Yeah, okay, sometimes I shamelessly pander for good evals. I’ll let you know if it worked after the class ends. Unless it doesn’t, in which case I probably won’t.)
During the podcast, I told my inestimable co-host, Peter Ledbrook, that we got a chance to use GPars in class. The app we used it on was all about the primary goal of the internet, which is to display cat pictures.
Peter then shamed me into writing a blog post about it, which you’re reading now.
I’ve actually written about this app before, for another client…

Gretty 1.1.9 is out!
March 3, 2015Posted by on
Gretty version 1.1.9 is out and immediately available at github, bintray, maven central and gradle plugin portal!
Gretty version 1.1.9 introduces full isolation of it’s own logging system (slf4j/logback) from the constituent web-applications. Now web-applications are free to use any logging system – Gretty does not interfere and does not force logback to be used.
Also Gretty 1.1.9 solves problems with farm configuration when farm is defined in the parent project and web-applications are defined in child projects.
At last Gretty 1.1.9 includes upgrades of the following components to their latest versions:
- jetty7: 7.6.15.v20140411 -> 7.6.16.v20140903
- jetty9: 9.2.3.v20140905 -> 9.2.7.v20150116
- selenium: 2.44.0 -> 2.45.0
- spock: 0.7-groovy-2.0 -> 1.0-groovy-2.4
- tomcat7: 7.0.55 -> 7.0.59
- tomcat8: 8.0.15 -> 8.0.20
Gretty is a feature-rich gradle plugin for running web-apps on embedded servlet containers. It supports Jetty versions 7, 8 and 9, Tomcat versions 7 and 8, multiple web-apps and many more. It wraps servlet container functions as convenient Gradle tasks and configuration DSL.
A complete list of Gretty features is available in feature overview.

Now Co-Hosting the Groovy Podcast…

Stuff I've learned recently...
When I first starting learning Groovy in a serious way, one tool I enjoyed was listening to the Grails Podcast. Glen Smith and Sven Haiges led a discussion about Grails-related issues on a regular basis. Of course, since they talked about new developments in Grails, they also had to cover new developments in Groovy, so the podcast was a valuable resource for both.
At the beginning of each podcast, Glen would say that he was podcasting from Canberra, Australia, and Sven was podcasting from San Jose, California. Of course, Sven might have been in CA, but Sven is actually a European and eventually moved back to Munich. That led me to contact Glen and ask to be the third person in the booth, arguing (a) that they needed an American, too, and (b) together we’d be Glen, Sven, and Ken, and how cool was that?
(To be honest, I…

Gretty 1.1.4 is out!
October 7, 2014Posted by on
I’m glad to announce release 1.1.4 of Gretty – advanced Gradle plugin for running web-apps on Jetty and Tomcat!
What’s new in Gretty 1.1.4:
- New feature: inplaceMode property, when assigned to “hard”, instructs Gretty to serve files directly from src/main/webapp, bypassing file copy on change.
- New feature: runner arguments for Gretty products.
- New feature: interactiveMode property allows to fine-tune Gretty’s reaction on keypresses.
- New feature: archiveProduct task, archives the generated product to zip-file.
- New feature: gretty.springBootVersion property allows to specify spring boot version (the default is 1.1.7.RELEASE) (issue #88, “Set Spring / SpringBoot version doesn’t work”).
- New feature: gretty.enableNaming property allows to enable JNDI naming on Tomcat (issue #64, “JNDI – NoInitialContextException with Tomcat (tried in 7x and 8x)”).
- Enhancement: now gretty.jvmArgs property is automatically passed to Gretty products.
- Enhancement in Jetty/Windows-specific lifecycle: useFileMappedBuffer is set to false for all Gretty tasks, so that Jetty does not lock css/js files.
- Enhancement in buildProduct task: now it automatically generates VERSION.txt file with the version and creation date information.
- Resolved issue #89, “How to configure fastReload?”.
- gradle wrapper to version 2.1
- Groovy to version 2.3.7
- SpringBoot to version 1.1.7.RELEASE
- Embedded Tomcat 7 to version 7.0.55
- Embedded Tomcat 8 to version 8.0.14
- Embedded Jetty 9 to version 9.2.3.v20140905
- asm to version 5.0.3
- Implemented support of Gradle 1.10 (still, using Gradle 2.1 is highly recommended!).
- fixed issues with groovy-all versions and logback versions in the webapp classpath
I highly appreciate your feedback!
Gretty 1.1.3 is out!
September 16, 2014Posted by on
I’m happy to announce that Gretty 1.1.3 is out!
New in Gretty 1.1.3: virtual mapping of gradle dependencies (of the web-application) to “WEB-INF/lib” directory. This feature is needed by some web frameworks accessing jar files in “WEB-INF/lib” (e.g. Freemarker).
Special thanks to @saladinkzn (Timur Shakurov) for introducing this nice feature.
Up-to-date Gretty sources are always available at:
All Gretty releases are also available as maven artifacts at jcenter and maven central.
