How to Use Maven with ZK

This chapter describes how to use the Maven repository hosted by ZK. (We assume you have known Maven) Here introduces you with a simple example of using ZK maven repository in your maven build environment.

Choosing ZK Edition

ZK has 3 editions:

  • CE (compact edition). Suits for personal use.
  • PE (professional edition)
  • EE (enterprise edition)

Please check the description about ZK Editions to know the differences among them and find the proper edition for you.

Add ZK Maven Repository to Your Projects

According to which ZK edition you use, add the corresponding repository to your project's pom.xml.

CE (Freely avaialable under LGPL)

 <repositories>
    <repository>
      <id>ZK CE</id>
      <url>https://mavensync.zkoss.org/maven2</url>
    </repository>
  </repositories>

PE-eval / EE-eval (60-days free evaluation)

The evaluation version has the exactly same features as the official (non-evaluation) ones. You use it to develop a POC and try ZK features before you adopt the official ones. This can eliminate the potential technical problems in advance. 


 <repositories>
    <repository>
      <id>ZK PE/EE Evaluation</id>
      <url>https://mavensync.zkoss.org/eval/</url>
    </repository>
  </repositories>
  • Note: Version number appending with -Eval has released since Jul. 18 2014. If you use it, please specify the version to *-Eval for all of ZK dependencies. For example:
<dependency>
    <groupId>org.zkoss.zk</groupId>
    <artifactId>zk</artifactId>
    <version>8.5.0-Eval</version>
</dependency>

PE / EE (premium users only)

If you are our customer or ZOL licensed user you can contact info@zkoss.org to apply for a premium maven account to use ZK PE/EE (or any other licensed ZK product) maven repository. 

 <repositories>
    <repository>
      <id>ZK EE</id>
      <url>https://maven.zkoss.org/repo/zk/ee</url>
    </repository>
  </repositories>

Login authentication

Licensed Professional and Enterprise customers will be given a set of user names and password upon your request. According to the official doc of Apache Maven, users can create global settings for maven.

  • Location (if not-existed, you can create it manually)
    • The Maven install: $M2_HOME/conf/settings.xml
    • A user's install: ${user.home}/.m2/settings.xml
  • Servers Element
  • If you add ZK PE or ZK EE as your repository, you need to add login authentication like following example
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
 		xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 		xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0
 		http://maven.apache.org/xsd/settings-1.0.0.xsd">
	<servers>
		<server>
			<id>ZK EE</id><!-- Same as your repository name -->
			<!-- Your premium user name and password -->
			<username>ryanwu</username> 
			<password>2k055ecret</password> 
		</server>
	</servers>
</settings>

Trouble Shooting

If you have problems switching from the evaluation repository to the licensed one, please check the followings:

Purge local repository evaluation cache

1. Add purge-local-repository plugin in pom.xml 

	<build>
		<plugins>
			<plugin>
				<groupId>org.apache.maven.plugins</groupId>
				<artifactId>maven-dependency-plugin</artifactId>
				<version>2.6</version>
				<executions>
					<execution>
						<id>purge-local-dependencies</id>
						<phase>clean</phase>
						<goals>
							<goal>purge-local-repository</goal>
						</goals>
						<configuration>
							<manualIncludes>
								<manualInclude>org.zkoss.zk:zkex</manualInclude>
								<manualInclude>org.zkoss.zk:zkmax</manualInclude>
							</manualIncludes>
						</configuration>
					</execution>
				</executions>
			</plugin>
		</plugins>
	</build>
  • line 16: ZK PE
  • line 17: ZK EE


2. Invoke maven clean to delete local zkex & zkmax repository 

mvn clean


Adding ZK library dependencies

Depending upon your project requirements your project might depend on different ZK edition. You can declare these dependencies in the pom.xml file, and Maven can resolve them by automatically connecting to ZK Maven repository. Here is how you can declare a dependency for the main ZK library and zul library for your project.

EE

<dependency>
	<groupId>org.zkoss.zk</groupId>
	<artifactId>zkmax</artifactId>
	<version>${zk.version}</version>
</dependency>

PE

<dependency>
	<groupId>org.zkoss.zk</groupId>
	<artifactId>zkex</artifactId>
	<version>${zk.version}</version>
</dependency>

CE

<dependency>
	<groupId>org.zkoss.zk</groupId>
	<artifactId>zul</artifactId>
	<version>${zk.version}</version>
</dependency>

Optional

<dependency>
	<groupId>org.zkoss.zk</groupId>
	<artifactId>zkplus</artifactId>
	<version>${zk.version}</version>
</dependency>
<dependency>
	<groupId>org.zkoss.zk</groupId>
	<artifactId>zhtml</artifactId>
	<version>${zk.version}</version>
</dependency>

For Maven to successfully resolve these dependencies groupid and artifactid must match with those published on ZK Maven repository as they constitute what is known as Maven repository coordinates. For a complete list of all ZK library groupid and artifactid combinations please take a look at a sample pom.xml file that lists dependencies for all publically available ZK libraries on ZK Maven repository.

Sample of pom.xml

Here is a sample pom.xml for a simple Java project that uses the ZK maven repository. 

<?xml version="1.0" encoding="UTF-8"?>

Check Available ZK Version

Please visit each edition's corresponding ZK Maven repository with a browser to check the available ZK versions. As of Oct. 2023, the latest version is 10.0.0-Beta.


Summary of JAR files

There's something you need to know about ZK's edition and package(s).

CE PE EE Description
zk.jar V V V ZK core functions, such as ZK Loader and Update Engine.
zul.jar V V V ZK XUL components (http://www.zkoss.org/2005/zul)
zhtml.jar V V V ZK XHTML components (http://www.w3c.org/1999/xhtml)
zcommon.jar V V V The common library that ZK depends on
zcommons-el.jar V V V ZK EL expressions (renamed as zel.jar since 6.0)
zel.jar V V V ZK EL expressions (since 6.0)
zkbind.jar V V V data binding, required when developing with MVVM
zweb.jar V V V The Web library that ZK depends on
zkplus.jar V V V ZK extra utilities integrated easily with other frameworks.
zkex.jar V V ZK additional components and features for PE
zkmax.jar V ZK additional components and features for EE
zuti.jar V shadow components for EE
client-bind.jar V Client MVVM for EE
stateless.jar V core of stateless components for EE
stateless-immutable.jar V immutables of stateless components for EE
zml.jar V
(only ZK 3) 		V V ZK XML components for generating XML output

This will be helpful when you modify your dependencies of projects.


BOM

ZK provides a "bill of materials" (BOM) which can be used by your projects simplify a pom.xml. You can use it as a parent POM or import it like: 

	<dependencyManagement>
		<dependencies>
			<dependency>
				<groupId>org.zkoss.zk</groupId>
				<artifactId>zk-bom</artifactId>
				<version>9.0.1-Eval</version>
				<type>pom</type>
				<scope>import</scope>
			</dependency>
		</dependencies>
	</dependencyManagement>

For a complete example, you can reference pom.xml of this project. You can also read a spring boot document to understand BOM usage.
