Run Jetty Run

This repository has been decided to be the official successor of the original "Run Jetty Run" at

New feature and bug fix will be performed here.
  • Run web applications with Jetty and Eclipse in one click!

  • Full maven support , simply run maven J2EE project without any config.

  • GettingStarted explains it all. Please see FutureDirectionsDiscussion to participate in the evolution of Run Jetty Run.


update site list.

Due to the Java 8 lambda issue, the nightly build is recommended.

About Java 9

The official Java 9 support of Jetty is start from version 10 which has not been released yet, but Jetty has released a version 9.4.8 with earlier Java 9 support, which has been supported by RJR too.


To use RJR with jetty 9.4.8 Java 9 support, you need add the following vm args to your launch configuration or you will get error as "java.lang.NoClassDefFoundError: javax/xml/bind/JAXBException":

--add-modules java.xml.bind

Migrate Note

Directly upgrading from old version to the current nightly build is not supported. Uninstall the old version via eclipse's plugin manager at first, then follow the GettingStarted to install the newest nightly version.

The current 1.3.5 nightly build can be automatically updated.


  • Version 1.3.5 is under developing.
    • 2018/02/10 Jetty 9.4.8 support is added (for earlier Java 9 support)
    • 2017/08/01 Jetty 9.4.6 support is added
  • 2016/01/16 RJR is officially migrated to github now.
  • 2016/01/12 1.3.4 has been released, which includes all unreleased fixes at original

Why this plugin?

Because running a web application in Eclipse should be as simple as 'clicking run'. No additional setup required.

The difference with WTP Jetty Integration

We think there are some benefits to use Run-Jetty-Run instead of WTP:

  • Performance WTP always copy all the resources to a temp folder , that slow down the process and you have to stop server then clean the resource sometimes if the resource locked. WTP solution also takes more time to start and terminate a web application.

  • The maven support It's a annoying to run maven based web application in WTP. Since we use same project classpath with default Eclipse JDT , so we could support maven dependency management (M2Eclipse Plug-in) easily. (Note that RunJettyRun did not required to install a maven plug-in , it's optional.)

  • Less steps to setup and run For using WTP Jetty , you have to install Jetty_WTP_Plugin , then find a runtime for it , that took your time to download a runtime and config it. You still have 3-4 steps after you install WTP plugin.But if you use RunJettyRun , there's already a built-in Jetty lib in the plug-in , simply "run" a project with Jetty by one click.

  • Also support Java project. Easy to use Jetty for every Java project but also a Dynamic Web Project , if you are writing some web widget , it's easy to test it with RJR.

Other benefits

  • Working with Eclipse JDT debugging/ hot deploy When you running RJR in debug mode , you could modify the code and apply it directly. Of course, all the breakpoint/inspector for java resource is working fine.
