How to create ZK Component Maven project
Create Project of Maven
- [File] -> [New] -> [Other] --> [Maven Project]
- Make sure Create a simple project is not ticked in the first screen of the New Maven Project wizard and click Next >.
- From the Select an Archetype screen, we'll need to add the ZK archetype catalog. Click Configure....
- From the Maven archetypes catalogs setting, click Add Remote Catalog... and add the catalog file:
http://mavensync.zkoss.org/maven2/
- Click Verify... and then OK to add the catalog.
- Remote catalog is empty.[1]
- Click OK in the "Preferences" dialogue.
- Now you should be able to find zk in the Catalog dropdown list.
- Select the zk-archetype-component from the list. (At time of writing this is at version 0.8.0).
- Next, fill in details for group id, artifact id, version number and package name.
- Property zk-version-since is missing.[2]
- Click Finish and the Eclipse status bar should say ' Creating zk-archetype-component ' and ' Updating Maven Dependencies '. If this is the first time you deal with ZK libraries, Maven will download the necessary dependencies to compile and run this example, and would be stored in .m2/repository in your home directory.

If you receive the error message Remote catalog is empty, this is most likely due to a bug in the m2eclipse plugin in v0.12.x, MNGECLIPSE-2757.
Until m2eclipse 0.13.x or newer are released, there are two possible workarounds:
- Install the "Older version" 0.10.x from the Installing m2eclipse website. You'll need to first uninstall m2eclipse 0.12.x, restart and then install 0.10.x from these install sites:
- Create the plugin from the archetype using the Maven command line tool mvn, then use Import existing maven project to add the generated project to Eclipse. please refer to Use the command line version of Maven for creating the project.
- ↑
The first time you run this wizard, m2eclipse will not yet have downloaded the zk archetype, and might not populate the zk-version-since property correctly, leading to an error message like:
- Unable to create project from archetype [org.zkoss:zk-archetype-component:0.8.0 -> http://mavensync.zkoss.org/maven2/], Archetype org.zkoss:zk-archetype-component:0.8.0 is not configured Property zk-version-since is missing.
How to run Maven project on Run-Jetty-Run
- Goto Run Configurations
- Double click on Jetty Webapp
- It will auto fill Project / Port / Context / WebApp Dir
- Click Run and browse http://127.0.0.1:8080/mycomps/
Packing your component
- Goto Run As > Maven package
- Your project will be pack into a war file and a zip file with source code.
Use the command line version of Maven for creating the project
- Here describes how to set up Maven.
- Go to the folder for your Eclipse workspace, then run this command.
- Calling archetype:generate -DarchetypeCatalog=http://mavensync.zkoss.org/maven2/ the plugin will first ask to choose the archetype from the zk catalog. Just enter the number of the archetype.
- It then asks you to enter the values for the groupId, the artifactId and the version of the project to create and the base package for the sources.
- It then asks for confirmation of the configuration and performs the creation of the project.
- In the following example, we selected the component archetype (numbered 1) and set groupId to org.test, artifactId to mycomps, version to 1.0-SNAPSHOT and package to org.test.mycomps.
$ mvn archetype:generate -DarchetypeCatalog=http://mavensync.zkoss.org/maven2/
